Mail does not move from Outbox to Sent Folder, but it does get mailed

I recently installed eM client on my new Win8 PC. It seems to receive and send OK, but my sent items remain in the outbox and although they actually get sent, they never move from the Outbox to the Sent folder. They just stay in the outbox. Is there a setting to make them move from Outbox to Sent folder? My old installation did this automatically.

Is it strange to answer one’s own post? I managed to get it fixed. It was the SMPT setting, it had to be set to legacy port 465. All is good now.

Great, I am glad you fixed it yourself.
