Exchange 2010 server clients randomly loose connection

[jimmy_2k]

Hi all

 

I have been having intermittent problems with my Exchange 2010 server which is on Server 2008 R2. The Exchange server will suddenly refuse Outlook 2010 connections from some users. On the Outlook client it comes up saying that The connection to the Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action. Outlook then pops up a box headed Microsoft Exchange, under the Microsoft Exchange Server, the schools webmail address is listed which is incorrect and the mailbox does have the correct AD login in the box. A reboot of the Exchange server usually cures this. However its happened a couple of times in a short space of time, its happening today after the server rebooted overnight following an auto-update via WSUS.

 

I have gone though the error logs and I can't find anything obvious, although it is a bit strange that users are getting a prompt listing the exchange server as the webmail address.

 

I am currently trying to persuade the school to go towards Cloud based email.
