Thank you for your feedback. The ability to enable and disable meeting chat in a meeting is on the backlog. We will share an update as soon as one is available.
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.

This is a must have in the dynamic partner organizational relationships of today’s age. The B2B guest is a start but notifications don’t work right well not at all on the mobile client. If your out of the office and need to stay in constant contact teams is not an option with out this capability. That’s a shame as other products do this. I would prefer to see this before the full Skype calling feature set is mirrored 1-to-1. Especially if you mobile device is enrolled into InTune. You can’t even log out and into another organization that’s blocked. So you either need two or more devices or talk IT into allowing you to get away with an unmanaged device and good luck with that option.
