Server error: Entry not found in index

when I tried to delete a mail in a user’s mailbox. An error occurred saying “Server error: Entry not found in index” but the document has been deleted.

any solution for this error?

Subject: What the error means

The error message means that something attempted to access a document based on the view index. But the view index was out of date. So it tries to call to a document that is no longer there.

As to why you are getting the error I am not sure though.
