Ensure guest access to a site or OneDrive will expire automatically

MédiaNível 1Revisão manualm365

Descrição

This policy setting configures the expiration time for each guest that is invited to the SharePoint site or with whom users share individual files and folders with. Expiration can be a number 30 to 730. The recommended state is 30. This setting ensures that guests who no longer need access to the site or link no longer have access after a set period of time. Allowing guest access for an indefinite amount of time could lead to loss of data confidentiality and oversight. Note: Guest membership applies at the Microsoft 365 group level. Guests who have permission to view a SharePoint site or use a sharing link may also have access to a Microsoft Teams team or security group.
