New Teams missing from Outlook

I'm experiencing the same challenge here. It seems Microsoft is discontinuing Teams Classic on March 31st. Yesterday, I initiated the process of uninstalling Teams Classic and transitioning users to the new version, only to discover that those I switched no longer have the Teams Add-in in Outlook. Consequently, I had to reinstall Teams Classic to get it back. I'm hopeful that even if Microsoft mandates a complete switch, retaining the classic version will ensure the Add-in remains functional. The crazy thing is that the Skype for Business add-in remains no matter what!!!

This situation is reminiscent of my initial switch to the new Teams, which lacked features including the breakout rooms feature.

A Microsoft school report would say - "must try harder!" 🙂
