I have a user who has just been upgraded to XP. All of a sudden they can't connect to their mailbox on exchange 2000. Outlook says they don't have permissions.
I've disabled the NT password authentication, but this will prompt the user for a password everytime they log on.
OWA works fine.
I've logged on as the user from my machine (windows 2000) and can read emails fine.
The temporary resolution has been to give everyone full access to the mailbox (active directory - exchange advanced - mailbox rights). While I was there I checked that the 'self' user had full rights - they do.
I'm stumped and I know my solution isn't secure or correct.
