Feature Differences Between New and Classic Teams

While this has been coming for a while, and Microsoft has not been shy about promoting the new Teams software, the final date of support for the older, classic Teams is July 1, 2024.

No, the sky won’t be falling and the classic version will not stop working on that date, but Microsoft will no longer provide updates or support for the older version after that date. The sky will start falling on July 1, 2025, the end of availability date, and precisely when the older client will stop working. Note that Microsoft will automatically attempt to uninstall the older version at the end of the availability period if you still have it installed.

So you haven’t been living under a rock and have seen the handwriting on the wall. Maybe you’ve already made the switch to the new version, or you’re putting off the switch as long as possible. Either way, even though Microsoft has long touted the feature parity between the two versions of Teams, there are some differences to be aware of. Some features are simply gone, other changes are informative in nature, and others just require a change in workflow.
