Resolve Google Workspace user account sync conflicts in Apple Business Manager
Using Auto Merge
When you first use Google Workspace to sync user accounts into Apple Business Manager, Auto Merge should be disabled and all user account conflicts should be resolved manually.
Important: If Auto Merge is turned on, new accounts are merged with existing user accounts in Apple Business Manager.
If you disconnect from Google Workspace and reconnect, you can choose whether to merge the Google Workspace user accounts. After all the user accounts are synced to Apple Business Manager, you can choose to disable Auto Merge to avoid any user account merge issues.
Sync conflicts can occur in one of the following ways:
The Google Workspace Sync connection was disconnected and connected back again, and an Apple Business Manager user account was imported using Google Workspace Sync.
An Apple Business Manager user account has a Person ID value and a Managed Apple Account that matches a Google Workspace user name you’re attempting to import using Google Workspace Sync.
