Set the automatic expiration for link based sharing
Set the global expiration for the Link Based Sharing by editing your Global Policy. If a user tries to access a share after it expires, the shared files are removed under the security context of the user's account. If you do not want the Link Based Sharing to have an expiry date, do not enable the Sharing policy.
- Select Policy > Global.
- Click Edit.
- Set the Sharing policy to On.
Enter the number of days the shared links will be active for.
The figure set here is also the number of days by which a share is extended when an expiry date is extended.
- Click Save.
