Ability to sign into a work account and a personal account at the same time
Yeah this needs to be a thing, not that I use it much these days but all of my skype contacts are connected to a different email account, rather than the email account which is bound to Microsoft's Account services, which renders the Teams kind of pointless. lol
I believe you can do this... or switch between profiles. It would be great if you can have multiple work accounts that you can switch between as I often have access to multiple Microsoft tenants.
