Exchange stops working on one of my SBS 2008 servers every 7 to 10 days. The users say that their outlook is disconnected. If I reboot, everything returns to normal for about 7 to 10 days, then it happens again. During these crashes, they can surf the net, work on their files etc..., I've tried to just restart the exchange services (even though they says they are all started and OK), but nothing get exchange back up and running unless I reboot. I can't see anything in the event viewer that would cause this, and I have another server that does not have those issues. I've read somewhere that others were having the same issues.

Hi, Since it is a SBS environment, I recommend you to post the issue in SBS newsgroup to get better help. http://www.microsoft.com/communities/newsgroups/list/en-us/default.aspx?dg=microsoft.public.windows.server.sbs Personally, I recommend you to monitor the event log and the performance of the SBS server.
