PS - List Office 365 Global Admins

If you need to get a list of the global administrators (or any other Office 365 role for that matter) use the following commands:

Import-Module MsOnline



This will return a list of Roles and the associated ObjectId, which you can then use to find the users that have the role.

The Global Admin role is listed as Company Administrator

Get-MsolRoleMember -RoleObjectId 62e90394-69f5-4237-9190-012177145e10

(Note that every ObjectId is unique to the tenant.)
