I would like to clean out my deleted items folder, and I have a bunch of old drafts that I'd like to delete permenantly. I can identify them by a little icon that looks like an "edit" flag:
I cannot find out how to query for them. "messageclass" does not have an option for drafts.
You'd want to create a new custom Search Folder, select "Deleted Items" as a source folder and specify the Criteria on the Advanced tab as follows:
Field: All Mail Fields -> Sent
Condition: does not exist
Do not forget to click the Add to List button. After opening this Search Folder, you'll see all your drafts there. You can right-click this folder holding the SHIFT key and select Delete All to permanently remove its contents.
An alternative is that you may Sort the messages in Deleted items folder by "Icon", so that the messages with the "edit" icon will be gathered together. You can use Shift key to more easily select these messages to delete them.
Tried the above but unfortunately didn't work for me.
I just did this and it worked:
Sort your emails by "From", the ones with "none" at the top will be your drafts.
