We can't open 'file_location.msg'. It's possible the file is already open, or you don't have permission to open it.

We're still having the same issue (it's March, 2019) in Outlook 2016. :(
This error is visible also to Outlook 2016 MSI version.

Is this problem the same as opening a desktop .msg file, closing it, then not being able to delete it until outlook is shut down?
I see this issue on (where is Help About? thats part of the Win3.1 Microsoft Design Guide? :) ) Office 365, hopefully latest April 2018 updates.
