Office 365, Email, Exchange, Outlook, Sent mail not being saved in the Sent Items folder

I can not see emails that I sent in Outlook's Sent Items folder, but they appear there when I send them from OWA.
For Outlook 2010/2013:
  1. Go to "File"
  2. Select "Options"
  3. Select the "Save Messages" section
  4. Check the box for "Save copies of messages in Sent Items folder"
For Outlook 2016/365:
  1. Go to "File"
  2. Select "Options"
  3. Select the "Mail" tab
  4. Scroll down to the "Save Messages" section
  5. Check the box for "Save copies of messages in Sent Items folder"
These instructions also apply if your Sent Folder is Missing from your Outlook Client.
