As part of updates to the Teams Desktop Client, Microsoft have released the following information as part of MC477839.
On January 9 2023, users on Teams 1.4 or earlier build will encounter a blocking page requesting an update to the latest version of Teams.
In the future, users of out-of-date clients will continue to see warning banners and later be blocked to ensure they meet security and compliance obligations.
How this will affect your organisation
The risks of not updating to the most recent version are:
- Your Teams desktop client may miss important security and quality updates
- The reliability of your Teams desktop client may suffer without recent bug fixes
- Your Teams desktop client may not be compatible with the Modern Lifecycle Policy, resulting in unpredictable behaviour and missing functionality
- Client versions with release dates that are more than 90 days older than the Current Version’s Release Date will be blocked because the above is incompatible with the service
What you need to do
To avoid disruption, please contact your local IT support service to update to the latest version of Teams.
Those on Teams versions older than the supported versions (any versions with release dates that are more than 90 days older than the Current Version’s Release Date) should support you to update your Teams Client version to the most recent version soon.
Your organisation should plan for a regular update to stay current and within the combability window.
Your organisation can find information on how to update Teams on the page here: Teams Client Update to learn more.
