I have migrated an exchange server from 2010 to 2013 using the coexist setup sometime ago. Sine then.. that 2007 server has been decommissioned.
I wanted to modify the default email address policy (lowest) and I am greeted with this warning: This email address policy is corrupted or was created in an earlier version of Exchange. Use the Exchange Management Shell to change the filter.
When I try to remove or add a new address format I receive the following:
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.
I create a new policy and I wasn't able to delete the default or change the priority
