We have a journal account on exchange and it was connected to Barracuda Message Archiver. Now the archiver complains it cannot connect to exchange. "Invalid Username or Password". I checked the password on our OWA and its working fine. Check the IMAP settings on exchange and they are all according to Barracuda KB. I called Barracuda and they said its something to do with the exchange authentication. I have no clue what to do next. Authentication on Exchange is configured as Plain text basic authentication.
