Office 2010 Pro

[EvanDavis]

I use Office 2010 Pro for my e-mail client. Never have I had any problems with it, but in the last couple of days I have had this pop up come up at least 5 times a day. I have logged in to my TalkTalk account and changed my password various times but have had no joy. Does anybody have any ideas ?

Do you think that the TalkTalk email server updated it's authentication protocol in a way that's messing with your app? I'm guessing you did not update the email app, so I'm assuming it was an update to the TalkTalk server that is causing this problem.
