Show at the portal the quota that is being used by the tenant
Please add at the portal the quota that is being used by the tenant to be able to request to Microsoft to increase the limit prior to have affectation and impact on the sync, b2b invites, app creations etc.
Current limit is 1 million, and when reach we will need to create a ticket with MS to increase the limit.
There's no way to know the value of the total currently in use.
The advice from MS was to run a:
(Get-AzureADUser -All $true).Count
(Get-AzureADGroup -All $true).Count
(Get-AzureADContact -All $true).Count
(Get-AzureADDevice -All $true).Count
(Get-MsolUser -All -ReturnDeletedUsers).Count
This is a messy solution in an environment with 1 million objects (users, contacts, groups, invitations, deleted objects, devices, etc).
