I have an email addresse from a company that forwards all of them into Gmail (Imap). Now, in Outlook 2007, when I delete an email from that account, the email just get greyed out with a horizontal line on it but won't go out of the folder. It won't delete... is there a way to have those email deleter permanently?
Check this: Deleting IMAP messages . From what I remember about IMAP, most clients do not actually delete messages, they just mark them for deletion (probably that's what you see with the greyed out messages with horizontal line; I've seen this in Squirrel Mail). One needs to purge the marked for deletion messages afterwards. That might even be in the IMAP specifications. However, I am not sure about the Gmail or Outlook implementations of IMAP.
