Microsoft retired Classic Teams in 2024: March 31 for most customers, June 30 for the extended deadline. It no longer gets updates or security patches, so if it is still on a machine, it needs to go. Here is the clean way to remove the old client and install the new one.
Remove Classic Teams
By hand, on a single machine:
- Open Control Panel.
- Go to Programs and Features, or Apps and features.
- Find Microsoft Teams in the list.
- Right-click it and choose Uninstall.
- Follow the prompts.
For a lot of machines at once, this PowerShell tool handles bulk removal: github.com/asheroto/UninstallTeams.
Install the new Teams
- Go to the official download page: microsoft.com/microsoft-teams/download-app.
- Click Download for desktop and pick Windows if asked.
- Run the installer.
- Launch Teams and sign in with your work account.
For a whole organization, push the new client with Intune or Configuration Manager instead of touching each machine.
A few things to watch
- Uninstall Classic Teams before installing the new one to avoid conflicts.
- The new client needs Windows 10 or later.
- A few features moved around, so give people a heads-up on the new layout.
