The messages are successfully copied to the other folder, but show up as unread.
"Mark as read" does show up as a filter option in the action list when creating a rule that applies to incoming messages, but I don't see it when creating a rule applying to OUTGOING messages. How can I accomplish this?
Here's the full text of my existing rule description string:
Apply this rule after I send the message
on this machine only
move a copy to the Archive folder
Update:
@xxl3ww notes that there are VB scripts out there that can accomplish this. I'd prefer not having to pay for one of these, though. Any free alternatives that anyone is aware of?
