I have a problem with an mixed environment of Exchange 2007 and Exchange 2003.
Actually, some users, which mailboxes are stored on exchange 2003, have troubles accessing OWA.
They authenticate on the OWA of exchange 2007, but just after, they had an 404 error page “404 – File or directory not found The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.” (left and right of the OWA page).
If i migrate their mailboxes to Exchange 2007, the problem don”t exist anymore.
These users that have the problem are exch 2003 users, but not all of 2003 users have the problem.
I think the trouble is located on my hubs servers, because we have other hub server on other sites, and when the problematic users try to connect to OWA of other sites, their mailboxes works fine … :???:
