If you’re idle on your system for five minutes, or more, Microsoft Teams will change the status. There isn’t any way to change this behavior. It is a feature so you can’t remove it but you can set a custom Available status and it will override it.

To override or block the Microsoft Teams away status from being set, follow these steps.

1. Open Microsoft Teams.
2. Click your profile at the top right.
3. Next to the Available status, click Set Status Message.
4. Enter any message you’d like or enter a period/full stop if you don’t want to write anything.
5. Open the Clear status message after drop-down and set it to Never.
6. Click Done.
7. Your Microsoft Teams status will not change to Away while you work in other apps.

Note: if you lock your system, or it goes to sleep, your status will change to Away.
