The June 2012 Release (build 220.127.116.114) is live: http://mfcmapi.codeplex.com.
This month we ship some pretty cool additions to MrMAPI: the –store flag gets a turbo boost, allowing you to open a store by Entry ID, which helps some of the automated diagnostics out there that use MrMAPI for data gathering. Also new is the ability to look up a specific property for a store, also by request of the diagnostics authors. For the troubleshooters out there who use MrMAPI for property lookup, check out the –flag switch, which allows you to look up flags on the fly.
Here's a change list - see the Issue Tracker on Codeplex for more details, or look at the code:
Finally – Surface!
