We have to remove an Exchange 2007 from schema because the server is no longer available. The SAN where it was crashed. It was a hub server we have to remove a CAS and mailbox too. Exchange 2010 has been installed to replace the servers and all mailboxes have been moved to Exchange 2010.
But I keep receiving messages such as
Some Exchange ActiveSync traffic to the External URL https://mail.mydomain.com/Microsoft-Server-ActiveSync is being blocked due to a misconfiguration of the virtual directory S1-EXCAS01\Microsoft-Server-ActiveSync (Default Web Site). Please make sure that the External URL is stamped correctly using the Set-ActiveSyncVirtualDirectory cmdlet.
S1-EXCAS01 is the Exchange 2007 client access server we've lost.
