Problem: Exchange 5.5 on Windows 2000

I have had this same problem with Exch 5.5 on wink2. I am assuming your in an Active Directory domain already?

In our environment there was an authentication issue between exch 5.5 and windows 2000 activedirectory. We were told by microsoft to update to the latest srvpck which we did. The problem was not resolved. We reverted back to NT4 and have since then migrated to windows 2000 and exchange 2000 successfully. But check out the two articles below which may be of help.

1) All users should have the rights to log on locally
2) There might be problems if you are going through a proxy server.
3) Depending on the authentication the browser might need to be IE instead of anything

go to technet or deja

I have that same problem right now and I have a fix for it: Several months ago we migrated exchange servers (5.5 to 5.5 changing org name) and ever since the migration some users have had this problem. I searched the microsoft technet db and foundnothing that would help. The only solution is to export the mailbox, delete it, re-create it and then import the mail back into it for the users that have the problem. I dont know exactly what has caused only a few of my 400 users to experience the problem but this has fixed it for all so far.
