Exchange 2007 outlook anywhere limited to 2 connections

I have an Exchange 2007 server. However only 2 connections are allowed simultaneously externally using Outlook Anywhere. If users A&B are connected then user C can't connect. If either A or B disconnects then user C can connect. OWA is working fine. Internal users are having no issues. Does anyone have any idea what's going on?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Do you have a Throttling policy enabled?

please inform me how you know that only 2 connections are allowed? are you receiving an automatic reply informing that? or only during troubleshooting you noticed that if A and B are connected C couldn't connect unless A and B are disconnected?

Thanks for the replies. I found the problem. This client has installed Exchange 2007 on a Windows 2008R2 foundation server. It has a 15 user license limit. I will work on a transition and migration solution to this problem.
