Hi Lance,

Thanks for contacting us and sorry for the inconveniences,

There are a few possible ways to fix this issue. One is to clear the cache and cookies of your browser, as well as the Teams app, to remove any traces of your daughter's school account. https://learn.microsoft.com/en-us/microsoftteams/troubleshoot/teams-administration/clear-teams-cache

Another option is to sign out of your daughter's school account from the Teams app and the browser, and then sign in with your own account. To sign out of the Teams app, click on your profile picture in the top right corner, then select Sign out. To sign out of the Teams web app, click on your profile picture in the top right corner, then select Sign out of Teams. Then, try to sign in with your own account and see if it works.

A third option is to use a different browser or a private browsing mode to access Teams, and avoid using the same browser that your daughter used for her school account. This way, you can prevent any conflicts or errors due to the cached data or settings of the previous account. You can also try to use the Teams desktop app instead of the web app, or vice versa, and see if that makes any difference.

I hope this helps!

Regards, Sola

Hi Mark,

Thanks for contacting us and sorry for the inconveniences,

• Check your Windows settings and make sure you are not signed in with a work or school account. To do this, go to Settings > Accounts > Access work or school and remove any accounts that are not your personal one.
• Clear your Teams cache and credentials by deleting the Teams folder in %appdata%\Microsoft and removing any entries that start with MicrosoftAccount:user= in the Credential Manager.
• Use a different browser to join the meeting with your personal account.

-Use an incognito window to join the meeting with your personal account.

Let me know if this helps or if you need further assistance.

Regards, Sola
