Tenant availability - guide

Enter at least 3 characters. Allowed are letters a-z and numbers 0-9.

☝ Your request for availability of the tenant will be answered by the Microsoft login service (login.microsoftonline.com).

All results are without guarantee, as a tenant can be registered at any time and Microsoft can reject a tenant that violates the guidelines.

What is a Microsoft Tenant?

A tenant is a company account such as company.onmicrosoft.com, is used for the M365 environment and remains part of your company forever.
A tenant name should be carefully chosen, as it will be visible to your customers when you share documents via Teams, SharePoint or OneDrive.

A tenant such as firstaname@company.onmmicrosoft.com can also be used for login or email communication if you have not verified your domain in the M365 environment.
