Are you sure you want to purge emails marked for deletion?
When you "purge" your account of emails marked for deletion, you are telling the server to permanently delete the selected emails. That is, once you purge messages, you cannot get those messages back. So, if you marked a message for deletion and want to unmark it (that is, not delete the message), simply: 1. Select the message in question. 2. Right-click on that message such that a menu pops up. 3. Select "Undelete" from the menu.
