There is a PRINT action on incoming emails via rules.
if you by chance BCC yourself, then you could create a rule that
If "I am BCC" & "From=<yourself>" ==> PRINT
You would also need to add to that rule to permanently delete the email as well (just to keep things clean)
But yes, this would be a nice feature
Alternative would be to create a MACRO in VBA (within outlook), assign it a button and add that button to the New Mail menu bar.
hope this helps you
msoutlook.info has an article on using OneDrive and a junction point to at least sync signatures on desktop clients (in case the link doesnt get through filtering, search for sync-signatures)
Its a bit of a hack, and I am also not sure if you want a Juntion, Hard or Soft link to make it work.
Hovering over the email subject does show the folder name where the email resides, but not the path.
However if you have similar folder structures throughout your overall structure, this may not be as helpful as you think.
eg <customer> <'Invoices' sub-folder>
Searching and then hovering would just show you the folders name and not the path.
So ability to show 'FULL Folder Path' in the search result AND when hovering would be great
