I have been using Outlook anywhere feature of Outlook 2010 to connect my remote clients to the Exchange server. It has been working fine.
On a remote site everything has been working fine for a particular user for a couple of years. All of a sudden Outlook has been coming up with a screen in the last 2 days saying "Enter username and password". It will not accept the password at all. So I reset the user's password and even that won't work. I deleted the Outlook profile and created a new one but again it won't take the password. Then I tried to add a different email account and it works straightaway. The strange thing is that the questionable email account which does not work in Outlook works fine when I use OWA.
A couple of days back I have been experimenting with VPN on SBS 2008 and I might have changed something for that particular user. It might be related or not. I am not sure.
It has completely baffled me. WHere do I start looking?
