My Email Link or Attachment Has Expired - How Can I Re-Enable It?
Expired shared email links and cloud attachments can be re-enabled on your Links & Files Dashboard in Mixmax.
From the Links & Files Dashboard, select the Deleted / Expired option from the panel on the left.
Next place a checkmark next to the file you want to enable, then click the Restore Selected button at the top right of the page.
Your file is now viewable again by anyone with permission to view the file.
