Outlook 2013: How to save Sent Items in a Shared Mailbox

Outlook 2013

In this post I’ll show you how to save Sent Items in a Shared Mailbox in Outlook 2013 or Outlook 2010.

In a lot of companies I work with there are instances where a department will use a Shared Mailbox which users will have Send As permissions to. When a user sends an email as the shared mailbox it will often end up inthe user’s Sent Items rather than the Shared Mailbox’s Sent Item.

To change this behaviour you need to make a Registry Edit.

You will need to add a new DWORD value called DelegateSentItemsStyle, and give it a value of 1.

Open RegEdit.

For Office 2013 browse to: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences

For Office 2010 browse to:  HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences


Add a DWord called ‘DelegateSentItemsStyle


Give it a value of 1

Restart Outlook

You’ll now be able to send emails as the Shared Mailbox, and Sent Items will be saved in the Sent Items of the Shared Mailbox.

    One problem: This solution works only with buffered mode enabled. We use virtual client machines so we don’t want the client to buffer the mailbox. MS have for some strange reason removed the Set-MailboxSentItemsConfiguration in Exchange 2013 so I’m still searching for a way to solve the problem with sent items in shared mailboxes.

    I’ve tried your solution and it works half way: emails are no longer stored in personal “sent items”, but also not storing to shared mailbox “sent items”. It’s like they were never sent, please advise
