Pop3 Outlook to Exchange 2007 keeps prompting for username and password on certain clients
Posted on 2010-08-18
We have a uk based Exchange 2007 server that is connected to by Outlook clients globally using Pop3 (Their choice of connection, not mine) and although the majority are fine we have a few users in another country that it keeps asking for the username and password every five minutes. I have setup a laptop with one of the users accounts in the UK and this works fine so i would say it's a location specific issue however they say that their Internet connection is stable unless they're connecting to anything on the UK server. Also it appears that OWA seems to work fine.
Any ideas on what to check on this ?
