Does Outlook 2016 have a Quick Look plug-in? Spotlight displays nonsensical text when a contact or email message is previewed in Spotlight.

Does Outlook 2016 have a Quick Look plug-in or has my installation of Outlook 2016  (16.14.1) been corrupted?
From what I have seen online and from my own uses Microsoft has not written a quicklook plugin for Outlook 2016.

It is odd though that you get some garbled text in the spotlight/quicklook window. On my Mac quicklook only shows an outlook document icon, the (presumably) UUID of the message and date created/modified/last opened info on the mail message.

So your garbled text might indeed be something going wrong with Outlook or even Quicklook trying to read a file it should not.
