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.
