When viewing the Office 365 Roles Report in the Azure section of the Active Roles Web Interface, it is observed that not all Azure / Office 365 roles are present.
Additionally, the Global Administrator role is not present in the report, even if enabled.
Active Roles uses the Get-AzureADDirectoryRoleTemplate PowerShell cmdlet to retrieve the Azure / Office 365 roles. Roles that are not currently enabled are not included in this report.
Additionally, when pulling roles via the Get-AzureADDirectoryRoleTemplate cmdlet, the Global Administrator role appears as Company Administrator. This is a display difference only, and they are the same group.
