          Here's a 2016 issue which needs a registry change tofix....

When you use double quotation marks to search a restrictive phrase in an online archived mailbox, a mailbox in online mode, or a mailbox in hybrid mode in Outlook, you receive unexpected search results.

Since it was patched in 2010 and 2013, but 2016 needs a registry change to fix it (why would they not just change the registry value in 2016 with an update?). This is something that may never get picked up without running this utility.
