Since my Droid Turbo updated to Android 5.1 my corporate calendar and contacts constantly sync and then un-sync! Everything worked fine before the update. I have deleted and rebuilt the account multiple times but this does not fix the problem. If I select "calendars to display" the calendar list will only show my device and gmail calendars. I then select "calendars to sync" from that screen and it will show the device calendar and gmail calendars but the corporate calendar is not listed. Shortly after I hit return to go back to the "calendars to display" screen, my corporate calendar appears. The phone calendar will then start populating with the corporate calendar appointments. Sometimes they stay on the calendar for awhile, sometimes they start disappearing while I am viewing the calendar. My contacts do the same when I can get them to sync. I am an administrator on our corporate productivity suite server so I have gone through this process watching my phone log on to the server while syncing. No errors occur on the server.
Another problem that occurred with the update is new appointments added on the phone under my corporate account will not sync back to my corporate calendar.
I have been using an Android since they were introduced and this is the first time I have ever had these problems. I have tried all the canned fixes that I have found on various web sits but nothing has worked so please do not repeat all the regular "check you settings" advice because I have been through all of them many times.
Thank you -
