@Pavel Yannara Mirochnitchenko ,
Do you mean that you cannot update Teams client?
Teams follows its own update process even if it is installed with Microsoft 365 apps. So, Teams will not be updated when you update Office apps.
The desktop client updates itself automatically. Teams checks for updates every few hours behind the scenes, downloads it, and then waits for the computer to be idle before silently installing the update.
Users can also manually download updates by selecting Check for updates on the Profile drop-down menu on the top right of the app. If an update is available, it will be downloaded and silently installed when the computer is idle.
If your desktop clients fall out of date, it will have an in-app alert. For more information, please refer to this article.
If I misunderstand your words, please give us more information of your situation. Thanks for your understanding.
