Hello Everyone! I have just recently implemented a Exchange 2003 Server into our environment, that?s co-exiting with a Exchange 2000 Server. What I?m planning to do in move all the mailboxes from the Exchange 2k server, to the Exchange 2k3 server, and decommission the Exchange 2k server. I have ran into something weird, we access our OWA from www.company.com/exchange; I can access mailboxes that reside on our exchange 2k through OWA with no problems; Internally and remotely. When attempting to access a mailbox on the Exchange 2k3 remotely, the user name/password box appears, I enter the credentials and it just sits there, the mailbox does not appear. When accessing the mail box internally that?s on the exchange 2k3 server it works. Any ideas? Thanks in advanced! Bilal
