17 Oct 2024

From 23 October 2024, the Microsoft Teams Classic desktop client will no longer be available for the following operating systems: 

  • Windows 7, 8, and 8.1 
  • MacOS 10.14 and older (i.e. Sierra, High Sierra, Mojave) 

This is only applicable to the Teams desktop client on these operating systems. It does not affect online or mobile access. 

What to do if you’re using one of these operating systems

UCT moved to the new Teams client at the beginning of the year, but there are still some people using the classic version. 

If you’re currently using Teams Classic, a toggle appears in the upper left corner of Teams inviting you to Try the new Teams. Turn the toggle on and click Get it now

The new version will install and thereafter reboot Teams. 

The next time you open the Teams client make sure that you select the Microsoft Teams app instead of Microsoft Teams Classic. 

Microsoft Teams Classic will then no longer be available to everyone from 1 July 2025.

Outdated operating systems pose a significant security risk to the UCT network

Machines that use outdated operating systems are putting the UCT network and your personal information at risk. These machines are no longer supported, or don’t receive security updates and patches.  It is therefore important that you use supported operating systems so that you get the required patches and updates.
