Error Message on MS Teams Desktop

Question

Hi there, I am continuously getting this error message when I try to sign into my Teams desktop app. Please help. "Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application '1fec8e78-bce4-4aaf-ab1b-5451cc387264' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account."

Hi @Tabatha Cormier

Please kindly note that here on Microsoft Q&A forum we mainly focus on questions about Teams for Business. If only the personal account facing this issue, please consider posting in the corresponding Microsoft Community for better help. Thanks for your understanding.

Are you logging in Teams via the default installed version of Teams (Teams for home or small business)?

How to distinguish (refer to the How do I know which version of Teams I'm using? part): Use Teams for work or school in Windows 11

I would also recommend logging via Teams on the web and see if it can help with this issue.
