    In our office, we have 8 PCs running Windows 7 and Outlook 2007. There is also a server running Small Business Server 2003 and Exchange Server 2003.

    Previously, we had old PCs running Windows XP and Outlook 2007, and did not have any problems connecting, but at the moment, Outlook running on three of the PCs displays its status as "Disconnected from Microsoft Exchange" randomly at least once a day. Restarting the PC sometimes fixes the problem, but not always.

    There were a number of issues I addressed on the server by using Microsoft Exchange Best Practises Analysis Tool, but the problem with these PCs still exists.

    I have searched through the application and system event logs, and the only corralation I have found is that around the times of the disconnections, the following error is displayed -


    The following fatal alert was generated: 10. The internal error state is 10.

    Can someone help me trace and resolve the issue ?

    Any help would be appreciated.
