Query on Access

Hi All

This might be a stupid question, but I would still like to ask: Is there any recommendation from Microsoft to restrict the number of Global Admins and Domain Admins? Specifically, in an organization, how many Domain Admins or Global Admins should we have? We currently have 11 Global Admins and 14 Domain Admins and want to reduce this number. Are there any recommended best practices from Microsoft, and if so, do we have any documentation on this?

    Sorry, there is no official document that sets a limit on the number of global administrators and domain administrators, it all depends on your requirements. But you could assigning the least permissive role means giving admins only the access they need to get the job done, to reduce the number of Global Admins. We could refer to the following document:

    About admin roles in the Microsoft 365 admin center - Microsoft 365 admin | Microsoft Learn


    Please note:

    Security guidelines for assigning roles
