Outlook 2010 – Shared Mailbox Sent Items Redirection

By Default Microsoft Office 2010 will save all sent emails into the primary mailbox ‘sent items’ folder, even when another email account is used in the ‘From’ field.

To change this behaviour and to make emails sent from a shared mailbox go into the shared mailboxes’ sent items folder you can install a Microsoft patch and enable the feature by changing a registry setting.

The following process details how to configure Outlook 2010 so emails sent from a shared mailbox will be saved into the shared mailbox ‘Sent Items’ folder.

To work, it requires:

  • The user to have full access to the shared mailbox
  • The user to have access to send from the shared mailbox
  • Outlook to have the shared mailbox added as an additional mailbox
