Android calendar not syncing with Exchange server

My boyfriend is using an Android (HTC Desire with Android 2.2) phone because he’s strictly against the current Apple mainstream movement. He has a Small Business Server 2008 in his office and his phone syncs email, contacts and calendars using Active Sync – at least, it should sync.

A few days ago he complained about calendar items not syncing from the phone to his Outlook client. As there are similar problems with the iPhone (see my article “New contacts created on iPhone do not sync with Outlook/Exchange”), I tried to figure out to which database the Android phone stores new calendar items. I noticed that I can only select “Google” and “PC Sync” – but no “Exchange”.

Some deeper digging in the internet showed that other users have the same problem. They describe that the sequence in how the accounts are added to the phone influence if Exchange is showing up in the calendar app or not. Many users solved the problem by completely reseting the phone and to set up the Exchange account before setting up the Google account.

This is not necessary! Here is a solution which works without completely reseting your phone:

  1. Delete the Exchange account under “Settings > Accounts and Sync”
  2. Delete the calendar data by going into Settings, Applications, and selecting both Calendar and Calendar Storage, then “Delete data”
  3. Re-add the exchange account.

Please note that your Exchange calendar won’t be deleted; but if you have items in your local calendar they will be gone after these steps!

  1. Thank you! After a week of pulling my hair out over this, surfing forum after forum, I found this on a Friday night after midnight. I should get out more I know.
    Finally, I can post calendar events from my EVO.

  2. I also had this issue where it would not sync. I rebooted the phone and all synced fine.

  7. This fixed worked for me. I will have to say that if you boyfriend had an iPhone he would not of had this issue since the article you reference above is about contacts and not calendar issues!!! Also the fix you provide for the iPhones contacts is just a settings issue and not a problem with the iPhone. When you have to start to delete data like the for Droid calendar issue that is a problem. Well i support a number of users and over the past couple of years I have little problems like this with the Androids I support and zero problems with the iPhones.

  8. I am having the same problem in my environment…the only difference is we have Androids, iPhones, Blackberries, Windows Mobile, and iPads and they are all experiencing this problem. Any ideas as to what would cause this calendar sync problem across phone platforms?

  9. THANK-YOU!! It worked!! This is the first article that I have found that gives me a fix for the Exchange calendar sync problem on my Samsung Captivate that started over 6 months ago (when I upgraded to Froyo?). Samsung and AT&T sites have been useless for this. I tried Touchdown, but it slowed my phone and turned it into a pocket heater.

  10. YOU RULE!

  11. Finally!!!
    Search everywhere for solution, even working with server administrators for solutions from their end. Thanks.

  12. Thank you very much … You’re a genius! My Exchange calendar would sync new appointments, but changes would creat a duplicate entry and deleted appointments would just stay put on the phone. Now, all is well on my HTC Incredible.

  16. Good idea but not functional in all cases. Unfortunatelly my Samsung Galaxy Note blocks calendar sychronization even after deleting all posible databases and accounts. All other elements (contacts, tasks, emails) work and even posting a new calendar event passed trough

  17. This worked brilliantly! Thanks for the post! I haven’t been able to update my outlook calendar from my HTC Evo for about yr. Woohoo!

  18. This worked for me too on Galaxy S3.

    Problem was that new calender events created in the phone did not sync to exhcange. Events created in Outlook synchronized just fine even before re-creating the account.

  23. OK, now that I have the Android calendar synced up, is it safe to re-add the Google Calendar?
