In your Microsoft 365 admin center you have options to restrict external sharing for your whole organization.
If your organizational-level external sharing settings are less permissive than your team or group sensitivity tag options, that sensitivity tag becomes invalid and will no longer be usable for categorization in ShareGate Apricot.
To be able to use the tag, you can use one of the solutions below:
- Modify your team and group sensitivity to match your organization-wide external sharing settings
- Modify your organization-wide external sharing settings to allow the group sensitivity tag to be used.
