If your Microsoft external sharing setting or guest access setting is not permissive, one of the following messages will appear in ShareGate Management to alert you:
The external sharing setting in your Microsoft 365 admin center doesn't allow sharing links. We'll only automate guest reviews.
The Groups setting in your Microsoft 365 admin center doesn't allow guests. We'll only automate external sharing link reviews.
The external sharing setting in your Microsoft 365 admin center doesn't allow sharing links or guests. Reviews can't be automated.
This usually happens when you activate the External sharing review policy but your Microsoft organization-level settings are too restrictive.
Details
Your Microsoft external sharing setting, guest access setting, and sensitivity labels can impact your ability to use the ShareGate external sharing and guest access management features---including the External sharing review policy, the Ask owner(s) feature, and reviews for sensitivity tags.
When a review notification is sent to the team or group owner, the review dashboard will only include the content available to ShareGate. For example, a review may only contain guests but not external sharing links.
If your Microsoft settings do not allow for either external sharing or guest access, the review notifications will not be sent at all.
