Installed a new Active Forums Enterprise, and we're working on setup.  When we try to enable email connector under a forum and save the settings, it initially appears to save.  But if we leave that screen and come back to it, nothing has been saved - it's back to being all blank / not enabled.  How can we troubleshoot?

That usually means that your settings are incorrect. The mail connector will validate your settings before saving. Make sure you have entered the correct site url, username and password.

Looks like Site URL and POP Server need to be correct or it does not save (even though it says it did save successfully).

Thanks Will.
