Hey Abhi,How long did you wait? it takes little bit of time to access mailbox through OWA and takes even more time to access through Outlook client due to replication and AD updation. Suggest you to wait for sometime and check...Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
