I am having issues where my users keeps disconnecting from the exchange server. I dont know why it keeps doing it but I did try my best to figure out the issues. The exchange server is just eating lots of bandwidth and I dont experience this before it just started after I setup the sonicwall and branch network setup. I use windows server 2008 and exchange 2007.

How can I prevent Exchange from continually disconnecting users?
