Adding access to our email in an already unstable Teams platform is the very last thing on our list.
Plenty of original functionality in Teams is still badly broken with support in North America supposedly so overwhelmed that Microsoft is already dumping paying customers like us onto graveyard shift off-shore support contacts, and some strangely incompetent off-shore support.
We expected Teams telephony to be fully stable a year ago, but find this month that SBC setup process is still broken, third-party Microsoft telephony partners still can't complete setups without invasive administrative access, the dialing capability that's supposed to appear in Teams for users may never show up without Microsoft intervention, and there are still dead telephone resources that the broken Teams and Skype admin centers will not allow us to delete (and have left Microsoft Support baffled and unable to correct).
Teams is still missing functions to purge stale user-to-user conversations for security and compliance reasons. Some of Teams subscriptions functions to add external content into channels are broken with cryptic errors.
And my favorite is a horrendous GPU acceleration bug when Teams users on new Intel-based laptops with a combo of Intel CPU GPU and Nvidia GPU cause the app to corrupt its own display space. Off shore support for that issue is so incompetent that they keep demanding network logs that we will never provide for such an obvious intrinsic bug in the Teams app.
