We are currently testing the new Tasks app internally. We will share an update as soon as it’s available.
Thank you for all your responses to the design survey. The survey is now closed.
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.
