We have a fairly simple email setup. A single SBS2003 box running Exchange 2003 and ActiveSync out to several iPhones, no SSL whatsoever. Has never been a problem before like this. Last night, power was out long enough for our battery to die, and server went down. Upon rebooting this AM, activesync will not work out to any iphones or other activesync enabled mobile devices (Droid, etc..). Checked that all services are running, IIS settings are unchanged and IIS is running, also confirmed it's not a router issue because the devices don't work behind the firewall either pointing directly to the local IP of the mail server. Beyond what I've already looked at, I do not know how to further troubleshoot the problem. Any ideas?
