As a modern online service, the Microsoft Teams client auto-updates every two weeks. Because Teams is governed by the Modern Lifecycle Policy, it is expected that users remain on the most up to date version of the desktop client. This ensures that users have the latest capabilities, performance enhancements, security, and service reliability.

Users on Teams desktop clients that are more than three months old will encounter a blocking page giving the options to update now, reach out to their IT admin, or continue to Teams on the web.

The behaviour how this software installs automatically on every computer with M$ Office365 feels a lot like malware. It installs the Micro$oft Teams desktop client on the regular office update. In addition it installs a program that will reinstall the Micro$oft Teams Desktop client on next reboot if just the client was uninstalled.

Who will ever want to install the Micro$oft Teams client for Linux that will be released next month.
