SharePoint Guest Expiry Query

Hey Sam

Thanks For connecting Microsoft 

• Expiration impact: When a guest’s access expires, their permissions are removed from the entire site, including access via sharing links, unless they have alternative access (e.g., through a Microsoft 365 group).
• Resharing behavior:
  • Original sharing links remain valid but are inaccessible to the guest after expiration. Extending access restores the guest’s ability to use these links without creating new ones.
  • Re-inviting the guest to the site restores site-level access (if previously granted), but resharing specific content may require generating new sharing links for individual files or folders.
  • To avoid creating new links, use the “extend access” option to maintain continuity of access to previously shared content.
