We have a few servers that are backend servers to the organization's front end server. The existing backend servers handle OWA requests with no problems.
We have created 3 new Exchange 2003 Enterprise Edition servers to do some mailbox migrations, however no users are able to access OWA or Activesync. This is happening on all 3 servers. The servers are all (FE and BE) on the same Exch2003 SP2. If I create a new mailbox on one of the new servers, I can access the mailbox fine from Outlook, but via OWA it gives me a 500 error.
If I take a working mailbox from one of the working BE and move it to one of the new ones it doesn't work, throws the 500 error and gives errors for Activesync as well and won't connect to the servers.
I've re-installed exchange on one of them, rebuilt the Exchange Virtual Directories, etc. And nothing seems to work.
Does anyone have any ideas that can help as we are stuck!
Is there some special procedure needed on the Front Ends or Backends so they are aware of each other with regards to OWA or Activesync? It's bizarre as regular mailflow works fine.
