Lost chats or teams

Hi Limar,

Thank you for sharing the details of your situation.

Please first make sure that you are signed in to Microsoft Teams with the same school account that you used in primary school. If you received a new account when you started high school, your previous class teams may not appear under the new account.

• You can also try signing in to https://teams.microsoft.com with your previous school account to check whether the teams are still available there.

If the teams are still missing, they may have been archived or deleted, your membership may have been removed, or your previous school account may no longer be active. Students cannot restore a deleted class team or add themselves back. Please contact the IT administrator or a former teacher at your primary school and ask them to check the status of the missing teams and your account.

Your sister should also contact her school’s IT administrator, especially if she uses a separate school account.

• In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support

I hope this helps move the case forward. Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.
