New Bug not on this list: when installing a fresh SP1 installation for a client to migrate to (have some clients specifically waiting on SP1 before considering an upgrade) I've notice a very annoying little bug:
If you wait until SP1 is installed to upgrade your default policy then it will be unable to do so, instead dumping out the same error you normally get form trying to edit it from the EMC.
Exact Syntax:
Set-EmailAddressPolicy "Default Policy" -IncludedRecipients AllRecipients
Exact error Dump:
The recipient policy "Default Policy" with mailbox manager settings cannot be managed by the current version of Exchange Management Console. Please use a management console with the same version as the object.
