Frequently Asked Questions

What should I verify before I remove any groups or users that should not have access (including any?

Remove any groups or users that should not have access (including any group that indirectly includes the external guest). File and folder sharing can differ because of inheritance, site sharing policy, sensitivity settings, or the user’s permission level. Check Manage access on the exact folder.

Why is it important to remove and re-create sharing on the parent folder?

It keeps a copy of current permissions and can then be edited independently. Document the change so future site membership changes do not create unexpected access. Confirm the account type, product version, ownership, and permissions before assuming the control is unavailable.

Can I safely test the step to open the affected SharePoint site in a browser and navigate to the on a limited scope?

Open the associated Power Automate flow and inspect Run history. The failed trigger or action shows the connection, permission, expression, or data issue to correct. Keep the relevant backup or confirmation until you have checked the result.

What final check proves I was able to configure external guest access to a SharePoint subfolder?

Repeat the action with a test item and confirm the expected history, sharing control, or flow result. Reopen the affected app or portal and confirm that the expected status persists.
