Outlook 2010 - Some users being constantly prompted to enter details
For the last few days, we have had a couple of users report pop-ups asking for them to enter usernames and passwords to use email. If they cancel the box or ignore it, everything still works as it should. If they enter the details, its still pops back up at random intervals. The users are not doing anything specific to trigger this although it does seem to happen more often when using the Send and Save feature in office applications.
Any suggestions? Proxy exceptions are in IE for our domain, Hotfix KB2553248 & KB 2553406 have been removed (google search suggests this) without luck.
