IT happened many months ago where a few users can't login to their POP3 account, via Outlook, mobile phone, tabletPC, etc. The issue was never resolved, those users switched to RPC/HTTPs/OWA

And more and more users are having the problem.

If I create a new user, the new users will not have this problem

 Error on Outlook
There is no event error logged on the Exchange server, AD server or the PC.

I have no clue what is going on.

Please help.
