Custom Presence in Communicator 2007 R2

I recently completed a deployment of Office Communications Server 2007 R2 and in my search for many technical articles, I stumbled across the ability to create custom presence in Office Communicator 2007 R2. (Microsoft TechNet article here) Obviously, for most people, myself included, there isn't a real business need for this so I kind of tucked it away in my "This would be kinda cool to try out some day" pile.

Well, eventually I was looking for a distraction and turned to the pile, finding this little nugget and gave it a try....to no avail. It didn't work! Oh well, stick it back in the pile.... I revisited this occasionally here and there over the next couple months, never able to get it working, never caring about it enough to invest any real amount of time in it. Well, tonight I ran across this article while looking up some security information for OCS that answered why this wasn't working.

In OCS 2007 R2, High Security SIP is enabled by default. (awesome!) so, it expects all transmissions to be secure. Well, had tried having the presence.xml file out on a network share, on my local hard drive, and in a SharePoint document library. None of which are considered secure transmissions. However, just slap an 's' at the end of the http for my SharePoint document library and voila! My custom presence works!

So, moral of the story is, if you want to use custom presence in OCS 2007 R2 and you haven't disabled secure SIP (and hopefully you haven't....) then you have to store the file in an https enabled location. So, something like, https://server.domain.com/folder/presence.xml

Now, I wonder how long it will take before someone notices that my presence is "out of my mind, be back later"...
