Exchange 2010 SP2 RU7
We are preparing to decommission one of our mailbox servers in a DAG and it currently contains no mailboxes or database copies. However, when we run get-mailbox -server OLDSERVER there seems to be a few mailboxes that still reflect this server in their ServerName and ServerLegacyDN attributes. The Database value for every one points to the correct database, which does not have a copy on OLDSERVER (but used to as of last week).
We haven't gotten any reports of user issues, and all databases have the CAS array as the RPC Client Access Server. Should these values eventually update on their own? Exchange is still running on OLDSERVER - should these values be manually updated prior to decommission?
Running an Update-Recipient on a few of these mailboxes had no effect. All Exchange services have been restarted on OLDSERVER.
