Hi @frob ,

A tenant can set a policy to control the number of days a sharing link lasts after a user shares some content with an Azure AD guest account (created automatically when sharing with an external user). By default, the expiring access policy is not set. A tenant or SharePoint administrator must enable it and define the sharing period in the Sharing section of the SharePoint Online admin center. The period can be from 30 to 730 days.

• Login to SharePoint Admin Center site at: https://YOURTENANT-admin.sharepoint.com
• Click on the “Policies” and then the “Sharing“ link in the left navigation.
• On the Sharing page, expand the “More external sharing setting” and enable the checkbox “Guest access to a site or OneDrive will expire automatically after this many days” and then set the number of days.
  

Once set, the policy applies to new sharing links. For more details, take a reference to this article: How to Use SharePoint’s Expiring Access Policy for External Users.
