Using older versions of Outlook for Mac in business environments
... I hope we can carry on using the old version until I retire!!
Good luck with that!
As you can see from my earlier Post (Nov. 13) I 'switched back' to the 'old' Outlook desktop app - using the toggle switch - and now nearly all my incoming emails are treated as Junk!
As for the compatibility between the desktop app, web interface (outlook.com) and Android app versions, it is laughable!
