Using Classic Outlook on Windows for personal email, calendar, and contact management
It occurs to me now that, maybe the version update was what prompted that too, because I was asked the other day if I wanted to, when I loaded Teams after a reboot. To be fair, I do also have Teams Premium, which could be the reason I have a different version as well. Sorry, I didn't think that all through before I spoke; it could also be as simple as a tiered rollout; I've not had time yet to research the release strategy.
