I have noticed recently that the same 3-4 users are disconnected from exchange most mornings when they start up their outlook. <br />
All users running Outlook 2007 &amp;&nbsp;Exchange 2003 <br />
Basically it prompts for their UN/PW so we enter that and it does not accept it <br />
So I reset the password and it works for a day maybe 2 <br />
Then the same thing happens again. This time I enter the administrator UN/PW and this works no problem. <br />
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 <br />
<br />
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<br />
<br />
Any suggestions?<br />

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
