Box expiry links
Introduction
By default, Box sets a time limit on how long a link will last until it becomes invalid and the file or folder is no longer accessible via the link provided. This can be changed when sharing out a file.
Box will send out emails warning you about expiring links.
Instructions
Navigate to Box Online
Sign in if prompted
Locate the File or Folder you wish to share
Hover over the file or folder
Click the Share Icon
Click Link Settings
Make sure the option “Disable shared link on” is unchecked
The link should no longer expire, meaning the file or folder will be accessible via the link indefinitely or when it’s deleted.
