It was too good to be true. Microsoft isn't adding support for multi-user sign-ins to Teams in December 2020 -- at least not in the way most all of us were hoping. Instead, true multiple work account sign-in to Teams is sounding like a 2021 thing.
Earlier this week, a just-added Microsoft 365 roadmap item made it sound as if Microsoft was finally delivering on a long-requested Teams feature[1]: The ability to switch between different work accounts in a single Teams client (without having to resort to various workarounds). Like a number of other Microsoft watchers, I wrote about the plan and more than 700 people liked my Tweet[2] about it. It's definitely a pain point for many.
But as the week progressed, Microsoft quietly added a caveat to that roadmap item:
"We're adding support within Teams desktop to be able to add one personal account, along with one work/school account[3], change their profile picture, and switch between accounts and orgs through Settings."
Note: This wording was not in the original Teams roadmap item. Thanks to Michel de Rooij[4] and a few others on Twitter who pointed out this change to me.
So, while it's true that you'll be able to switch from your work/school account to your personal account in Teams desktop by December 2020, you won't be able to switch between multiple work accounts this year. My contacts say that's a 2021 thing. (I haven't heard whether H1 or H2.)
I asked Microsoft for comment on the roadmap change and the date for multi-user work-account switching and didn't get a response.
Microsoft is encouraging people to try using Teams not just for work, but for home/family
