Cannot log in into teams

Dear @Saidatul Asma,

Thank you for posting your question in the Microsoft Q&A forum.

As I am also a moderator, I have the same experience as you and other users. Moderators and contributors, including external Microsoft employees in this forum, cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas.

To help me check this issue, could you please confirm:

• Are you logging in on a new phone (Android or iPhone)?
• Do you have Microsoft Authenticator installed on your phone?
• Are other Office apps (Outlook, OneDrive, Word, etc.) working normally?

I have reviewed a previous case with a similar error code, which you may refer to for comparison: Tried to login but getting the error

I hope to receive your confirmation and feedback soon so I can assist you further. Thank you.
