"We can't open this attachment" error message in Delve


Consider the following scenario:

  • You browse to the Home view in Office Delve.

  • You see email attachments that are presented on cards.

  • You click the link to one of the attachments.

In this scenario, you receive the following error message:

We can’t open this attachment

The email may have been moved or deleted.


This issue occurs when a message is permanently deleted in Outlook, or the Deleted Items folder is cleared which previously contained the attachment. Delve indexes items from Outlook but after a message that has an attachment is permanently deleted, it takes some time for it to be removed from Delve.
