Server side synchronisation was working prior to rollup#2 except for Appointments, contacts and tasks. I upgraded to rollup#2 in the hope that this would correct the issue. However after applying and running "Test & Enable Mailbox" it
all fails with "The mailbox xxxxx has been disabled for synchronizing appointment, contact and tasks due to unknown error. The owner or the associated email server profile yyyyyyyy has been notified" also " An unexpected error occurred while
receiving email. the mailbox xxxxxx has been disabled for receiving........." and a similar message for sending. The equivalent set of messages are produced for all users. Dynamics CRM is running on a virtualised Windows Server 2012 R2 whilst Exchange
2007 is running on an SBS 2008.
