In Teams for your personal life, people can search for you with your phone number(s) or email(s) on your Microsoft account profile. If you prefer to limit how people find you, you can turn off either your phone number, email, or both.
To turn them off:
Open your Teams app on your mobile device.
Tap your profile picture or the More icon.
Tap Privacy then tap How others can find you.
In the privacy settings, it will show you the email(s) and phone number(s) from your Microsoft account. You can turn the toggle for the email or phone number on or off. These changes should start reflecting immediately in Teams.
Note: If you disable your contact details, your profile will not show up in search results for people who’ve never chatted with you in Teams.
