Recently I have received several e-mails asking for help and advice for building OCS applications.  While I normally do try to take the time to answer these to the best of my ability, with coding speeding up and more deadlines to make it seems unlikely that I will have a lot of spare time in the next several weeks.

Probably the best place to post these questions anyways is at http://forums.microsoft.com/ocs2007/default.aspx?siteid=57.  This site is monitored by members of the OCS team here at Microsoft as well as by OCS MVPs.  Therefore, you have a very high chance of finding the answer to your problem there.
