Hi all, I had a strange issue that came up after I reconfigured our receive connector in exch2013.
I have Exch2013 with Cu5 and a 2010 sp3. In order to fight spam I needed to reconfigure a new connector that's a bit locked down compared to the default frontend that's open to all remote networks, so in the new connector under the scope settings I put our internal network ip and disabled the default frontend connector that was created during install. Since our exch2010 box is the main server that sends in and out, and has better antispam features, this is where all emails went through and got routed to the 2013 box.
After restarting services, all was working including iphones and androids, except for Macs with outlook 2011, they were suddenly not able to connect to the exch2013 box after the changes. I looked at the transport logs but I couldn't see anything showing why these users were not connecting, event viewer as well. It did block a lot of spam from getting through, but I had to revert back to the default front end connector just to get the Mac outlook users working again, has anyone seen this before, or any other settings I might have missed. If anyone can get me some ideas or pointers, I'd greatly appreciate.
Thanks in advanced.
