In Exchange 2010 SP2 RU4, we’ve added support for Calendar and Tasks folders to Retention Policies.
If you currently use or plan to use Retention Policies, this has important implications for your messaging environment.
- Beginning with Exchange 2010 SP2 RU4, administrators can create retention tags via the cmdline for use with the Calendar and Tasks default folders. The supported retention actions are: DeleteAndAllowRecovery, PermantlyDelete, MarkAsPastRetentionLimit and MovetoArchive.
- Default Policy Tags (DPTs) used to move or delete items will now apply to Calendar and Tasks folders.
