Updated 1 month ago by admin

This article applies if you have an existing Azure Active Directory connection in Settings -> Active Directory and you wish to be able to identify shared mailboxes. By default, shared mailboxes synchronised from Azure Active Directory (AAD) are identified as standard users (objectClass=user) which means they are subject to billing. To exclude shared mailboxes from billing, you must grant the existing USS AzureAD application access to the Office 365 Exchange Online API.
