How to Fix Office 365 Admin Portal Access Issue?
Our experts have compiled some of the most effective methods to fix the unable to access Office 365 Admin portal issue.

- Sign into your alternative Office 365 admin account in the Microsoft Admin Center.

Multi-Factor Authentication can sometimes block sign in attempt due to some issues. You can try to disable Multi-Factor Authentication and try to re-register MFA again to set it up again. Learn the steps for this method below:
- Log into Microsoft Entra ID Admin Center with an alternate Global Admin account.
- Go to Identity > Users > All users and choose your locked account.
