  1. You are great! Thanks a lot. This is the only free working system to Sync it all!

  2. Worked like a charm.
    Thanks a ton Svetlana.

  3. Thanks for sharing this. Well done!

  4. Thanks Svetlana for the wonderful piece of information. It helps a lot.

  5. Hi, Svetlana. After reading your post and all the published Q and A's, I'm still having trouble. I use Outlook to pull my yahoo (sbcglobal.net) email from the server and into the software. I have used the Google Calendar Sync software for years to sync (2-ways) between Outlook and my gmail account so the calendar events in my Outlook populate on my (Android) cell phone, and vice versa. While no changes were made to software / settings, this stopped working recently: calendar events do not copy from Outlook into my phone, nor do events added on my phone populate into the Outlook calendar on my laptop. I have triple-checked the settings on GCS, including to be sure "2-way sync" is selected. I tried the suggestion from a previous poster to set up Google's 2-step verification + app-specific passwords, to no avail. Any thoughts?

    1. (Also tried uninstalling and reinstalling GCS software using your supplied links, with the same results.)

      1. Hi Chris,
        Can you recall any other recent changes, such as installing new antivirus software or Outlook add-ins? Also, did you install SP 1 for Outlook 2013?

  6. OMG thanks Svetlana, total lifesaver, one of the most helpful posts I've ever encountered.
    Thank you!!!

  7. The link to phpnuke.org only brings up version 0.9.4.0 of Google Calendar Sync and the description says that there are "limitations" and that you should purchase the it to remove the limitations.

    1. Hello Jim,
      Thank you for pointing this out. When I posted the link, it opened the correct file. Please use this direct link instead: http://goo.gl/xAeU3V

  8. Regarding 2 step authentication, just wanted to note that Wayne's comment in 31 above works perfectly.

    Thanks Svetlana for the best description of this process and options anywhere!

  9. Svetlana,

    Great post - synchronization of google calendar and Outlook is configured and working.

    Thanks for your help!

  10. Hi Svetlana,

    I have been doing more test and now it is not working with my cellular or google. I have try some try found on the web (because it looks like I am not the only with this problem) and one test work but then it didn't.

    Whatever I schedule in my cellular or google are ok on both platform it just that it is 1 hr off in Outlook.

    I found this http://suefrantz.com/2011/11/01/appointments-off-by-an-hour/

    What do you think of this program. Is it worth it?

    Regards,

    Chantal

    1. Hi Chantal,

      As far as I understand, they recommend switching to a paid version of gSync. I cannot say anything about it because I tried only a free version of this tool when writing this article. It worked fine for me, but on the other hand I’ve never had this 1 h. late problem, so I do not know whether gSync will really be able to solve the issue.

      Anyway, I believe it's worth trying free means first : ) BTW, the link you found also says the problem is related to DST "It all started when they changed the dates for daylight savings time. Apparently Google Calendar Sync is coded in such a way that it recognizes the old dates for daylight savings time."

      I've found Microsoft's recommendations for Outlook and time zones that do not observe daylight saving here, probably this will be helpful: https://support.microsoft.com/kb/982987/en-us

      1. Hi Svetlana,

        Thank you, I will wait and see when GMT change to DST on March 26 if this get resolve otherwise I will check the paid option.

        I am in EST and we change DST on March 09.

        Thank you again and have a great day,

        Chantal

  11. Hi Svetlana,

    I have a problem with my Outlook since I have change for the 2010 version on Monday. If I set up an appointment in my cel phone or in Google calender it appear 1 hr earlier in Outlook.

    Do you know what I need to do. I had a technician work on this most of the afternoon and couldn't resolve it.

    Regards,

    Chantal

    1. Hi Chantal,
      There's only one thought that comes to mind - check whether you have the same time zones and DST (Daylight saving time) set in your cell phone, Google Calendar and Outlook.

      1. Hi Svetlana,

        For some reason it is working with my cellular but still not working with Google Calender and Outlook. As for the setting they are both set for Eastern time but I don't see anything about DST.

        Should I try to reinstall Google Sync?

        Regards,
        Chantal

  12. Hello,
    I followed your directions (very helpful) but then found a download that syncs my Outlook & Google calendars actively, rather than statically. Now I have duplicates of everything in my calendar! How do I get rid of the static calendar sync??

    Thank you!

    1. Hello Jen,
      For me to be able to help better, can you please specify which exactly method of static syncing you used? And what tool for dynamic syncing you downloaded?

      1. Hello!
        I followed your instructions in the section above called "Import / export calendars between Outlook and Google" because I wanted Outlook items to appear on Google, not the other way around. I then used Sync2 to get Outlook to supposedly sync on the hour with Google, but I am finding that it has not been doing so. Advice?

        Jen

        1. update: the sync finally kicked in and I'm seeing new Outlook items in Google.

          1. Alrighty, now I know that my version of Office is 64 bit - so is there a different tool I can use to get rid of the duplicates? ODIR doesn't run on 64 bit versions of Office.

          2. ok, last one: Windows is 64-bit but I can't figure out how to find if Office is 32 or 64...

          3. To be more specific, the error message says: "Unable to register the DLL/OCX: DllRegisterServer failed: code 0x80004005."

          4. Actually, the ODIR page says that my Windows and Office versions being 64 bit or 32 bit make a difference - how do I find out what mine are? I have Windows 7 and Office 2010 Professional Plus.

          5. Hi Svetlana,

            Thank you for reminding me that I could remove the other sync tool - but now the ODIR won't install - there's an "unspecified error" :( IDEAS?

          6. but (fyi) the duplicates are still there from the static calendar import.

            1. Hi Jen,

              Thank you for the update. You can remove duplicate items from your Outlook using this free tool: Outlook Duplicate Items Remover.

              If you also set one-way syncing from Google to Outlook, described in "How to synch Google Calendar with Outlook 2010 and 2013 (read-only)", you can turn it off in this way: in your Outlook, switch to the File tab > Account settings > Account Settings... > Internet Calendars. Select your Google calendar and click the Remove button.

              I am really sorry that my post has caused these troubles to you. I'm doing to add a note that only one synching method should be used to avoid duplicates. Don't hesitate to contact me again if I can help any further.

  13. Hi Svetlana, Thank you for your article. I have followed the directions using the old application of google sync and deleting the 9.5 file. However when I arrived at the {00062FFF-0000-0000-C000-000000000046}\ file there was only a 9.3 file? Help.
    Thanks

  15. Hi Svetlana,

    I tried to download the old application but it does not exist anymore.
    Can you help me in anyway in getting the old Google Calendar Sync?

    Pietro

  16. Hi Svetlana,
    many thanks for generous aid. tried couple of solutions, neither of which worked for two way sync btw outlook and google cal and made google cal editable in outlook. Your post solved the issue.

    1. Hi Svetlana, the google calendar sync workaround is fully functional, however the data generated in outlook is only pushed to google cal, and in magical way does not appear in android (that is synced with google cal).
      If event is generated in google cal, then both outlook and android update accordingly. Kind of tricky, and I don't understand the way outlook generated entries are pushed to google cal but do not reach the mobile.

      1. Hi Alibek,
        Thank you for your feedback! Regrettably, I am totally unfamiliar with android syncing issues since I am an iphone user : ) Really sorry for not being able to help you with this.

  17. Hi Svetlana, I am using the old Google Sync with Outlook 2010. Works fine except when Outlook is not running I get a dialogue box asking which Outlook profile to use. 'Outlook' is my only profile and I have checked the dialogue box to make it the default profile to no avail. Is it a requirement that Outlook be running for Google Sync to do its thing or is there a registry setting I could use to force the Outlook profile to default? Thank you!

  18. Hi Will,

    Thank you very much for your kind words. Regrettably, I don't know any syncing tool for Outlook that would not require admin rights :( The only alternative that comes to mind is using some third-party online service like SynqYa.

  19. Svetlana - You are a tremendous help with this article and follow-up posts. I did not find the help I need and thought I would ask. My company was using Lotus Notes and I was using a sync software called calsync to sync my Lotus Notes calendar one way to my Google calendar. It did not require Admin. Rights and so I could install it on my work computer. My company now went to Outlook and I can find no equivalent to Calsync... everything I've found, including all your recommendations require Admin Rights and I am not able to use them. Do you have any suggestions? By the way, here is the link to Calsync (I really want to find an equivalent for Outlook). http://sourceforge.net/projects/lntogoogle/

  20. Hi Svetlana

    I would like to import and update ics file from google to Microsoft Outlook existing Calender. I tried but it shows me as separate Internet Calender.

    Can you please guide.

    Thanks.

    1. Hi Chintesh,

      After you choose the location where to save the .ics iCalendar and click OK, Outlook will display a dialog asking you to choose whether you want to open the new calendar as a new calendar or import it into the existing one. And you click the "Import" button.
      Importing iCalendar (.ics) file

  21. Svetlana,

    I managed to get my e-mails synced between my gmail account and Outlook 2013. (I guess that's a feature that works just by adding the gmail account to Outlook.) I need to sync my calendar and my contacts, with the calendar being the priority. I installed the old Google Calendar Sync and it looked like it installed properly, but then I read the note above in the instructions that said, "Note: Google Calendar Sync only works with your default calendars in both Google and Outlook." I have several other calendars that I created and that I share with others. Am I correct in assuming that these calendars can NOT be synced using GCS? Before I start downloading other 3rd-party tools, which of the other alternatives allow for 2-way syncing of ALL calendars under my gmail account? Thank you for your help!

    Paul

    1. Hi Paul,
      This is true, the old Google Sync works with the default calendars only. I'm afraid there are only 2 possible ways to get it to work with several calendars and neither is free. You can upgrade to a paid Google Apps account (a trial version is available, so you can use it first to make sure it works right for you) or use a commercial third party tool. As far as I know all free versions, at least those I tested when writing this article, work with one account only. I personally would go with the Google App account, because the fee is not very high, it provides other useful features and is sort of official.

  22. Hi Svetlana - I synched my gmail calendar with Outlook, and am now able to view my google calendar in my Outlook calendar. However, I would like my google calendar appointments to appear as "Busy" in Outlook when others are trying to scheduled appointments with me (in Outlook). Is g-Syncit the best option for this?

    1. Hi ASM,
      It would be quite logical if it worked that way. But I've never tested this myself, so I cannot say with certainty whether the Busy status will appear in Outlook. Sorry for not being able to help you with this question : (

  23. I've been looking for this link for the old Google Calendar Sync for about 2 years to no avail. I've literally had no calender sync for 2 years. THANK YOU!

  24. hello guys,

    i want to setup group calendar for imap/smtp mail server can anyone tell me the procedure that i will follow to setup group calendar in outlook 2010.
    so that it will sync automatically.

  25. On a slightly different issue, I am having trouble syncing up my outlook email on Windows 8.1 with gmail. Even when I try send and receive or update the gmail folder in outlook I dont see the latest emails that I see in the web based gmail. I use IMAP. I removed gmail and added it again. It did fine the first time and then I stopped getting new email.

  26. Hi Bob,

    If you have the 2-step verification enabled, you should see the "Turn off 2-Step Verification" button on this page; if not then you will see "Start setup".

    You can find the detailed instructions on how to turn off the 2-step verification on the following page (from Google support): https://support.google.com/accounts/answer/1064203?hl=en

    Also, you may try Wayne's solution first (please see comment 31 above). He seems to have found a way to make it work with 2 step authentication as well. I personally did not try this solution because I've never turned on 2 steps on my google account. If it works for you, please take a minute and post the result here for other users to know. Thank you in advance : )

  27. I have read some more of the comments but they do not tell how (what steps) to determine if you have 2 step authentication. I don't recall ever setting it up, but how do I determine if I have 2 step and how do I change it to one step.

    BTW. I still get the Username and password don't match error message.

  28. My calendar sync stopped working. It would sync 30% and give error code 2016 (or something like that). I uninstalled it.

    Then I followed your instructions and used the backup link to re-install calendar sync. Now when I try to sync I get this message: Username and password do not match. You provided xxxxxx@gmail.com. Please enter your full email address (including@domain.com).

    How do I fix this?

    Thank you.

  29. Great write-up, but I have to say that I gave up on SynqYa - the set-up is anything but intuitive and, after three hours of cross-eyed concentration, I have achieved nothing...

    But, good news that the Google Calendar Sync can still be found. I was afraid that a new laptop would mean the end of Gmail/Outlook calendar sync.

  30. Hi Karin,

    I think you can try to use the old Google Sync tool. If this does not work for you for some reason, then check out third party tools, as an alternative. For example, gSyncit works with Vista SP2, though the free version provides syncing for calendars only.

  31. I am using Windows Vista and Outlook 2010. Until recently I was able to sync with my Iphone 4S with no trouble. Now I cant and Apple support has not been able to resolve. I guess my option is to sync with Google. Is there a way to sync Outlook 2010 and Google Calendar from Vista SP2? (I also need to sync contacts and notes) Thank you

  32. You can set up a password specifically for Outlook, you don't need to disable the 2 step process. Go to the 2-step options from your Google security settings page. Go to "App Specific Passwords". Name your new password, ("Outlook work, Outlook Laptop" etc) and it will generate a random set of letters/numbers. Copy that, then paste it into the password line for your Google Calendar Sync program... you will now be able to sync and keep the 2-step process.

    1. This is extremely valuable info. Thank you Wayne!

      1. Thank you! This works.

  33. I have my Google calendar and Outlook 2010 synced(one way only: Google to Outlook) but have a few appointments (three right now and they were all reoccuring)that have not/will not clear out of my Outlook although I've deleted them on BOTH.

    They should go away from, my Outlook calendar once I've deleted from Google and they 'appear to' as they no longer show up on the Outlook calendar but the Outlook reminders keep showing up in my Outlook deleted email every TWO hours (refresh time as set) even though the appointments have been deleted from BOTH calendars

    Any idea how to actually get rid of them? Not a HUGE problem but its starting to bug me!

    Thanks!

    1. Hi Chuck,

      This might probably happen if you have several devices connected to your Outlook and Google accounts and those two appointments somehow got stuck on one of the devices. I am not sure it's really the case, but this is the only explanation that comes to mind.

      1. Hi,

        Events are not synced if its reoccurring/one time event send from someone else (not yourself).

  34. I used MS-Outlook 2013 but the calendar sync between Google and Outlook became such a nightmare that I looked for alternatives and eM Client is the answer. for a single email account it is free. It does automatic calendar sync, read and write from eM Client to Google Calendar.

  35. Are there any privacy concerns with SynqYa? Could they use the information I give them to hack my gmail, install bots, steal my calendar information or anything like that? I like this idea but the company seems a little suspicious.

    1. Hi Matt,

      I've never heard of them doing anything like that. But if you have such concerns, you'd better not use SynqYa and try some other solution instead.

  36. We are a gaggle of volunteers and opening a new scheme in our community. Your website offered us with valuable info to work on. You have performed a formidable job and our entire group can be thankful to you.

  37. Hi Thomas,

    It's great that your Google Sync is up and running again! And thank you for posting this information, I think it might be very helpful for others who've run into the same problem.

  38. FYI, it worked. I am back to in service. Turning off the two step verification corrected the problem...Thank You so much...

    1. This is coming 6 months late, but for anyone else you can keep two-step verification by getting an app-specific password. Go to https://security.google.com/settings/security/apppasswords and generate a one-time password for the Google Calendar Sync app.

  39. I did activate the two-step authentication. I believe I need to get to my trusted computer (home) to deactivate it. Will let you know if it corrects the problem...Thanks

  40. I have never faced error 2016 myself, but a quick search in google shows this is a common problem. You can try the solution published on this blog, the fix is described in Update 4/27/09b. Hope this helps.

  41. Hi! So glad to have found this webpage... such GREAT info! I tried loading the Google Ap Sync as I had used it in the past with ho issues, but I randomly (about 85% of time) get an error message #2016... do you know what this is for or how I can resolve it? It is so frustrating that Google stopped supporting this sync ap. Thanks again!

    1. Hi Svetlana,

      Thank you, I finally got to install the Google Calendar Sync and it work. Thank you very much I really appreciate your support.

      Chantal

  43. Hi,

    I just had a technician sync my gmail addresses and calender with Outlook. I want to use Outlook for everything. The problem I have is I can't make any changes or add appointments in the Google calender while I am working in Outlook.

    What is my best option to be able to have Outlook & Google sync both way. I have Outlook 2007 and windows 8.

    Thank you,

  44. Hi Thomas,

    This issue may turn out to be a side effect of 2-step authentication, as reported by Robmmichaels (see comment 16 above). Do you happen to use (PW + PIN code) authentication on your Google account too or a usual 1-step authentication?

  45. Great articles, I thought it would fix my problem. I used the old sync to keep my Google calendar updated from my work Outlook. It no longer connects giving me a message of wrong password. I tried re-entering time and time but nothing. I deleted the program and reinstalled using your link but same problem. Error states:User name and password do not match. You provided XXX@gmail.com. Please enter your full email address (including@domain.com). I am using Outlook 2010, any help would be appreciated...Thanks

  46. Hi Robmmichaels,

    I have never tested the 2-step authentication on my Google account and cannot state with certainty whether this can cause the issue. Anyway, you can try to switch back to 1 step authentication and see if this gets Google Calendar Sync to work.

    1. Works with 2-step verification. You will have to use the application based password generated by google.

  47. Hi, thanks for the advice how to install the old, un-supported Google Calendar Sync. It installed fine but claims my Google account and password are not correct (which they are). I am wondering if it is because I activated the 2-step authentication feature on my Google account (PW + PIN code). Do you think that is the problem?

  48. I must have deleted the calendar sync when I was deleting and uninstalling some old programs. Thank you very much! I used the download link above and reinstalled Calendar sync on my win 7 pro machine and I am using it fine with office 2010 pro. (outlook 2010) as well as with office 365 (outlook 2013)

    Thank you for taking the time to produce such a helpful article.

  49. Hi Russ,

    To my best knowledge, the old Google Calendar Sync worked for calendar items only. The new version of Google Apps Sync (available in paid accounts) definitely works for contacts too.

    As a free alternative, you can check out the following third party tools: gSyncit (described in this article), GO Contact Sync Mod (open source tool to synchronize Outlook contacts with Google Mail), Local Sync, Contacts Sync (paid and free versions are available). I personally tried only gSyncit and it worked just fine on my Outlook 2010 / Win7.

  50. Thanks for the great info. I am using the good old gmail sync option for calendar. Does this work for contacts? If not, is there a free sync for outlook to gmail contacts?
