This past weekend I installed SP3 on our Exchange 2010 server (it was on SP2). We are using retention policy tags and policies and have been for 14 months at least. After a user reported some missing Tasks, I started doing some digging to find out if Tasks were somehow included in RPT's that were of the "All other folders in the mailbox" type. I came across an article that mentioned Calendar and Tasks were included in the default RPTs (http://blogs.technet.com/b/exchange/archive/2012/08/14/calendar-and-tasks-retention-tag-support-in-exchange-2010-sp2-ru4.aspx
) with SP2 RU4. I assume SP3 includes whatever changes the RUs for SP2 included, so this 'feature' came with SP3 too.
So, I am wondering if there is a way to create an RPT (within the EMC) that will either exclude Tasks and Calendar items or allow setting a time period for them to remain in the user's mailbox. I found an article (same one as in the above link) that provided a registry setting on the Exchange server that would disable this feature, but I was wondering if there might be a way to create an RPT instead.
