Shared Mailbox – Emails sent won’t show up in Shared Mailbox sent folder

Problem:

You send an email from a shared mailbox in Outlook and the sent email does not show up in the sent folder of the Shared Mailbox but it does show up in your sent folder. I tested this with the portal and it seems to work correctly through the portal.

Solution:

  1. Login to the Office 365 admin portal
  2. Expand Groups and Select the Shared mailboxes
  3. Select the necessary shared mailbox
  4. Under Sent items, click on edit
  5. Enable the first option (copy items sent as this mailbox)
