Hi,
Recently we are having a problem where most outlook connections display the message " Connection to microsoft exchange has been resotred" . i rememeber i was palnning to make a change on the cas server for one of the *.exe.config file, but not sure whether i really made the change.

Does any one know of .exe.config file which would cause such a issue?

My Exchange is running on E2010 SP1. It was migrated directly from E2k7 SP3 to E2010 SP1.

My server at the moment has close to 2800 Mailboxes with 24 GB RAM on the mbx server with 8 duo core processors and the CAS with 12 GB and 2 processors.

I am not sure what you are trying to configure in a config file to solve this issue.
What version of Outlook are you using? Are you running in Cached or Online mode? Does this happen to everyone or just a subset of users? When it does happen, does it affect everyone for the exact same time period? How long does the outage last? Are you have network issues with your CAS server? Can you run a constant ping on your CAS and see if you are losing any pings at any time?

Hi,

Please answer Tim"s question and let us know whether the issue occurs in Cached Mode or Online Mode.

To troubleshoot the issue, I suggest you access the following website to run Office Outlook Connection test.

Meanwhile, please open Application log in Event Viewer and check whether there is any error message on the client machine. If so, please upload the Event log to the Skydrive ( www.skydrive.live.com ) for research.

Run Outlook and collect the Netmon trace

=========================

a. Download NetMon 3.4 from the following website and install it on the computer

http://www.microsoft.com/downloads/details.aspx?displayFamilyID=983b941d-06cb-4658-b7f6-3088333d062f

b. Launch NetMon3.4.

c. In the Microsoft Network Monitor 3.4 window, click Create a new capture tab …

d. In the new tab, select all the Network Adapters in the Select Networks window.

e. Then, switch to Network Monitor, press F5 to start NetMon.

f. Try to launch Outlook again. When the error occurs, go to step 7.

g. Go back to the NetMon window and press F7 to stop the NetMon.

h. Press Ctrl+S to save the Netmon file named test.

i. Then please upload to SkyDrive (www.skydrive.live.com ) and share the link to me.

Thanks.

Novak Wu
