Important: Delve is retiring in December 2024. You can find similar features in other Microsoft apps. To make your transition off Delve as smooth as possible, we recommend you explore alternative options to Delve in Microsoft 365.


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.

For more information about what you'll find in Office Delve, go to Connect and collaborate in Office Delve.
