Thank you much sir. You should not have to remember what version I am on no matter how young you are. I am on Exch. 2010. Yea, that is a lot of connections, I will dig in on it.

It is optimized to provide no more than "that many" connections. If you exceed that number, it will have a negative performance impact. How much is somewhat debatable. You don't mention your version of Exchange (and perhaps you have done so here many times before, but I'm over 50 and suffer from CRS syndrome). If you are on 2010 or 2007, I'd spend some time with Exmon figuring out how the user exceeds 16 connections. That's a lot of connections.

Now I know I can increase that limit with a regedit but we have never had this before. Thoughts on what could be causing this on his end? I know nothing about the machine yet, other than he was using Firefox. Downside to regediting this limit upwards...suggestions on a reasonable number?
