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.

Integration with Outlook is planned. We will update you as we have more details.

Just lending my vote and voice to this feature request. Been nearly four months since it was announced the integration is planned. Any further insight into timing? Thanks.
