Alex & the Teams team
The engineering team is continuing to work on adding support for multiple accounts on desktop clients. We will first launch support for 1 work/school account and 1 personal account so users can enjoy Teams for work and personal side-by-side. Windows and MacOS. Support for multiple work accounts is still being worked on and will come at a later date.

Thank you for your feedback. The team is currently planning for this work, we will share an update as soon as one is available.
