I also am still using the old Outlook - and I guess that will become unavailable in due course, but in January I retire! HOORAY!
When I ca choose my own mail software I plan to explore what else is available, and not use Outlook. Fingers crossed.
I confess I am not enthusiastic about Co-pilot. The whole Teams experience has made document control more confusing and difficult, in my opinion. I have lost more document content in the last year (due to OneLook manically saving everything at every keystroke) than I lost in the last decade or two from forgetting to save.
Teams seems to be designed to protect people from the consequences of being idiots, and it can't.
Though yes, please, do keep me updated on and developments, or top tis for Co-pilot!
And thanks to everyone on this thread for the moral support about Field Chooser :-)
