Is IMAP and POP fully supported in my setup? I have all Exchange 2003 backend mail store servers with a new Exchange 2007 CAS (Client Access Server). OWA works fine however when I try enable IMAP access for users on the CAS I get this error. Set-CASMailbox -Identity user@domain.com -IMAPEnabled $true An Exchange 2007 server on which an address list service is active cannot be found. At line:1 char:1+ S <<<< et-CASMailbox -Identity user@domain.com -IMAPEnabled $true Firstly should need to do this if the user already has IMAP permissions set in AD/Exchange 2003? When I look at the properties of the mailboxes listed on the CAS (under Recipient Configuration/Mailbox) and choose "Mailbox Features" I do not see IMAP listed. I just see OWA, ActiveSync, Unified Messaging and MAPI When I hit the 2003 exchange servers directly using IMAP it works just fine. Any ideas? Thank you
