Hello, all: I've got a WS03-functional domain, 3xWS03 DCs/GCs (one is an Exch03 Server). I've installed a WS08R2 member and prepped AD for MSExch2010, installed MSExch2010 and moved 1 mailbox to it. It sends and receives, coexisting with MSEx03. I can use an internal URL to get to OWA. However, after making necessary changes in the firewall and anti-spam hardware, I'm unable to reach OWA from the Web, and smartphones no longer sync (of course). I'm attempting to determine methods of testing how/why this failure is occurring. Any suggestions are greatly appreciated. If I have left out pertinent information, please let me know and I'm glad to provide. Thanks in advance for any help.

Can't connect to OWA/ActiveSync from Internet
