I kept getting MSExchange ActiveSync 1040 warning events on many client’s Exchange servers (2003 and 2007).  The event itself sent me to http://support.microsoft.com/kb/905013 (thanks Microsoft, that does help!) which pointed to a firewall issue.

Since we are using Cisco routers at these sites, I did a quick Google and turned up nothing.  Darn, time to hit the books

I threw the following command in to modify the timeout in the CBAC inspect of HTTPS.  I set the timeout to 10 minutes.

ip inspect name <inspectname> https timeout 600

So far the warning event hasn’t shown back up…
