The problem:
Using outlook for mac 2011 v14.2.5 I consistently get calendar sync errors with office 365 approximately every 30 minutes. The error message is formatted as follows:
Description:
Could not synchronize record: <calendar-entry-name>
Error:
Could not synchronize record: Discussion to Exchange Server: <account-name>
Details:
Set Action is invalid for property
Error Code: -19847
The facts are as follows:
-If I delete the calendar entry it obviously solves the problem
-If I use outlook for windows these errors do not happen
-Contacted MS tech support for outlook and paid their fee, rebuilt identity, etc... no change other than I am poorer
-Outlook has other email accounts configured, gmail, icloud, etc.. as imap no issues, they are not used for calendaring
-I use outlook for all calendaring, I sync to ical only so i can see calendar on my iphone
-Followed these steps no issues found: http://support.microsoft.com/kb/2409331
So at this point I am stuck, I am out cash for tech support that says its not the client its exchange. Well its your exchange server microsoft.... oh umm well we errr... yeah. Any ideas welcome and appreciated.
