This is a known issue with Outlook 2013/2016/2019 connecting via IMAP.

Symptoms:

  • Mail isn't populating
  • Sent Items, Outbox, Junk Email folder etc. show up as the subfolders of the Inbox folder.

Until Microsoft releases an update to fix the issue, use the following workaround:

  1. In Outlook 2013, navigate to Home > Info > Account Settings > Account Settings:
    Change account settings
  2. Select the IMAP account and click Change (or double-click the IMAP account name)
  3. Navigate to More Settings > Advanced and enter INBOX in the Root folder path field
  4. Click OK > Next > Finish
    Root folder path



  1. In Outlook 2016/2019, navigate to File > Account Settings > Account Settings.
  2. Select the IMAP account and click Change (or double-click the IMAP account name)
  3. Enter INBOX in the Root folder path field
    Root folder path
  4. Click Next > Done

All default folder will show up as top-level ones and mail will start populating to the Inbox folder.

Additionally, these settings can be accessed from the Windows Control Panel > Mail. If you do not see Mail, change the "View by" option from Category to Small Items. In Mail, click Email accounts, then double-click on the IMAP account, click More Settings and follow the instructions above.
