Issue: I am migrating from one Exchange 2003 SP2 server to another (retiring hardware on "old" server as it is at the end of it's support life - this server is "EXCH1"). I have built a new mailbox server ("EXCH2" - exchange 2003 Sp2) and have migrated a few test user's mailboxes over. To ease the transition, I have installed an Exchange 2003 Sp2 Front End server ("EXCH-FE") to allow for users to continue to hit OWA during the migration.
When I log into OWA on the EXCH-FE server, any user that is on the "EXCH2" server works fine. Any user that is on the EXCH1 (the old one) gets a partially loaded OWA page - that looks a little like OWA in a basic browser (like Safari or Firefox) - it is ugly and doesn't load. Please see screenshot below.
I am running two Windows 2003 R2 Sp2 domain controllers. The EXCH1 server is Windows 2003 Sp2 and the other two Exchange servers are 2003 R2 Sp2.
all are at the same patch level.
Also- for the mailbox that is not loading correctly, i have this in the event viewer: thanks
