A curious issue has arisen, and I cannot find anything on the subject. We have a few users that just started receiving a popup in Outlook Professional 2010 SP1 that says "Windows Security Microsoft Outlook Connecting to "firstname.lastname@example.org" INSERT A SMART CARD. We do not use Smart Cards and we have not made any changes to the Exchange 2010 server. I cannot find anything to point me in the right direction.
From time to time, it also asks for a password again, but the user never actually needs to key it in. I've tried re-naming the folder in the c:\Users\username\AppData\Roaming\Protect folder. Same results.
Does anyone have any advice?
