Delete Azure AD accounts that appear in Apple Business Manager
When deleting an account in Azure AD, that account will not be deactivated in Apple Business Manager until you permanently delete the user from Azure AD. See the Microsoft Support article Restore or remove a recently deleted user using Azure Active Directory.
If you aren’t an Azure AD administrator with permissions to delete accounts, send the URL for this page to your Azure AD administrator and work together to delete the accounts.
When you connect Apple Business Manager to Azure AD using SCIM, accounts are synced from Azure AD to Apple Business Manager. If the account is no longer needed in Apple Business Manager, you must delete that account from Azure AD, not simply remove it from the Azure AD Apple Business Manager app. Deleting an account from Azure AD deactivates it in Apple Business Manager.
If an Azure AD account is removed from the Apple Business Manager Azure AD app by mistake and a new user is created with the same user name, Apple Business Manager:
Won’t merge the account and the previous account is marked as a conflicting account
Will merge the accounts if Auto Merge is enabled
Important: Don’t remove an account. You must delete an account. Also, don’t reuse a user name for 120 days in the Apple Business Manager Azure AD app.
Delete an account in Azure AD
Depending on where the account exists, you may have more than one way to delete an account:
Sync Only Assigned User accounts: The user can be deleted from the Azure AD Apple Business Manager app or deleted from the Azure AD Users tab.
Sync All Users accounts: The user must be deleted from the Azure AD Users tab.
To delete an account, see the Microsoft Support article Add or delete users using Azure Active Directory.
Search for and select all the accounts you want to delete.
You must wait 40 minutes for Azure AD to sync the change to Apple Business Manager for the accounts to get deactivated.
