I took over the IT department here and I am not great at troubleshooting Exchange.
We have a Exchange 2010 server running on Server 2008 behind a SonicWall TZ205.
We cannot get Active sync nor OWA to work outside. The OWA works internally. I have run the connectivity test for active sync internally and externally and it fails.
I am not sure if it's something within the settings of Exchange or the firewall.
Need help with some troubleshooting steps to pinpoint which one it may be.
