Strange log entries

["Mike Heitz" <mikeheitz () upshotmail com>]

I've run across a couple log entries on my OWA server. I'm pretty new to
security (about a decade as a network admin, now taking on more and more
responsibility) and have Googled the Propfind command... only a handful
of results (including a MS Whitepaper I am currently reading).

Does anyone know what this is exactly? We do not have Instant Messaging
enabled on the server... my main concern is that the Username that was
listed was my own!!! I've used Visual Route to trace the IP addresses
back with marginal success (one got lost after a bunch of hops and the
other ended up in Pittsburgh, PA).

Any ideas or info would be greatly appreciated. Thanks!
