I know Win Phone is at end of support but I still use it as a work phone and see no reason why I can't access Teams from the Edge browser built in (Teams app having been disabled due to dropping support). Instead I have to use my personal phone which I don't want anything work related on so don't want to install the app and have work account linked to the phone. Edge on Android.. Not supported. Chrome... Not supported!
Yes I could get a new work phone, but it works fine for basic features I need. Calls, text, email, bit of simple browsing. Teams dropping support I can deal with if it's just "you may experience issues", but blocking access is harming productivity.
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.
