I have created a new Notes 7.01 e-mail account at work, on a 7.01 Domino server.
Mail arrives into the in-box.
Read, highlight and then delete using the delete key.
Document/s then appears, as expected in the Trash view.
Then empty the Trash, by using the Empty Trash action.
Go back to Inbox, document/s are not there as expected.
Stop and restart the Notes Client.
Go into the mail file, the recently deleted documents are there!!, interestingly with a new file received time.
Have been round the above loop 4 times. Each time the deleted documents re-appear with an updated file received time.
Mail properties - Soft delete enabled, with 48 hours selected, as per normal set up.
