Hi All, Iam running a service which reads mails from mailbox via IMAP from exchange server 2003. But recently its been migrated to exchange 2010, and iam getting error from my service as "cannot connect to the server".It was working fine with exchange 2003. I have verified the IMAP connectivity from the following link: http://support.microsoft.com/kb/189326.IMAP connectitivity was successfull and then restarted the services but still no luck. Service writing logs in the eventviewer as "can not connect". Kindly help me on the same Thanks, Ramram
