I have noticed recently that the same 3-4 users are disconnected from exchange most mornings when they start up their outlook.
All users running Outlook 2007 & Exchange 2003
Basically it prompts for their UN/PW so we enter that and it does not accept it
So I reset the password and it works for a day maybe 2
Then the same thing happens again. This time I enter the administrator UN/PW and this works no problem.
Also getting a pop-up saying that the certificate has expired and we install the certificate and again it works for a day or 2. The only thing is that the Certificate has been expired since June 2012. PLease see the file attached
We thought it may have been an issue with the database size so we done an offline defrag which cleared up around 25GB of space on the exchange database
