I've got several hundred emails in an IMAP folder in outlook, when I delete them and then hit purge, some of them stay in the folder with little deleted icon next to them, but they are not removed from the folder.
So when i hit delete, the font gets strike-through, but when i hit purge, the only thing that happens is that little icon is displayed. Other messages in the folder don't seem to have this issue and they are correctly purged.
Finally, when I click any messages that has strike-through and the icon, both strike-through and the icon disappear and the message is no longer indicated as deleted at all...
How can i get rid of these messages with the icon?
