When using Outlook 2007 to connect to sbs 08 w/ exchange 07 via "rpc over http" remotely I seem to have reached some limitation on the number of clients that can connect. I have one client that can not connect until another client disconnects from the server via the same type connection.
If this is performed locally inside the firewall, outlook uses a tcp/ip connection type and does it correctly. If you change the connection type to the "http" type when inside the firewall, you get the same results as remote users.
I can not find anything that details this type of limitation or how to increase the number of users connecting.
Any ideas?
