Having some issues around integration CRM Online with Exchange Online by using Server Side Sync.
When Testing/Enabling user profile for synchronization I receive "Unknown" errors on Outgoing/Incoming test, however Appointments/Contacts/Tasks test works fine.
I've setup an O365 "CRMSync" service account using a K2 license and gave it AplicationInpersonation rights on Exchange Online. And using "Credential Specified in Email Profile" for Authentication method. The exact error is:
"An unexpected error occurred while receiving email. The mailbox ****** has been disabled for receiving email and the owner of the associated email server profile Microsoft Exchange Online has been notified."
I understand there is very little technical info available for CRM Online server side sync specifically with Exchange Online, but maybe someone has encountered this before? Also are there any other way to get a more descriptive error reporting besides looking at alerts?
