I just recently installed Exchange 2010 that coexists with Exchange 2003. Exchange Servers are as such:
Server 1 - Client Access/Hub Transport
Server 2 - Mailbox
Server 3 - Exchange 2003 (will be decommissioned shortly)
When I try to create a new mailbox on Server 1 the mailbox is created successfully. But on Server 2, the Exchange Management console does not show this mailbox in Recipient Configuration > Mailbox. If I create a mailbox in Server 2, the same thing happens, it doesn't show up in Server 1.
If I try to connect to the new mailbox using OWA, after logging in, I get an error page stating somewhere on the page that the mailbox cannot be found.
Any suggestions?
