[***Ingo Gegenwarth has published an better version of this script that handles the changes made recently to ActiveSync on Exchange Online see  https://ingogegenwarth.wordpress.com/2018/01/03/eas-folder-mapping/ ] I came across an interesting Blog post this week from Jim Martin http://blogs.technet.com/b/tips_from_the_inside/archive/2013/06/17/activesync-mapping-a-collection-id-to-a-mailbox-folder.aspx which explains how the ActiveSync Folders located under the device folder in ExchangeSyncData folder tree map back to the real Mailbox folder that is being synchronized or accessed via ActiveSync.
