Frequently Asked Questions
What is an onmicrosoft.com tenant?
An onmicrosoft.com tenant is the default domain and dedicated cloud environment provided by Microsoft when you sign up for a Microsoft 365 business subscription. It is used to manage your organization's user accounts, services, and administrative settings.
What exact information do I need to verify my Microsoft 365 admin account?
To prove ownership of the tenant, you must provide your company name, billing details, active subscription information, registered phone number, and your alternate email address.
Can I reset my Microsoft 365 administrator password without calling support?
Yes, if you previously set up self-service password reset with an alternate email or phone number, you can use the 'Forgot my password' link on the sign-in page. If those options are not configured and you are the sole admin, contacting support is mandatory.
