Definitely a step backwards in usability and functionality.

  1. I have to do a hold before I can do a search. I've done searches for a dozen or more years and NEVER needed to place a hold. Why that requirement now? If I need a Hold I'm quite capable of placing it. We don't want pointless Holds all over our data.
  2. Deduplication is gone. The biggest failure with this "update." We could be search 50 mailboxes and each may have a copy of an email, what possessed Microsoft to think that having 50 copies vs. 1 copy of an email was somehow better.

Sorry, but these "improvements" make my job harder, not easier.

BIG FAIL!

The Deduplication function has been removed.  This is a hugely regressive.  As part of a large organisation, this was a key function in identifying and obtaining a copy of relevant emails.  We could have the same email in many thousands of mailboxes.    Why was it removed?  Are there any plans to  re-instate this function?
