How to archive an Imap Outlook 2016 inbox

This was not intuitive to me, and it took a while to figure it out.
The help inside Outlook on “archiving” does not piece together the steps.

  • Close outlook
  • Set up a new archive folder using control panel -> mail
  • Open outlook
  • Group inbox by date
  • Drag oldest group into the archive folder

With thanks to this post for realizing I needed to use control panel.
