Prior to Exchange 2010 SP2 RU4, the only way to control where sent items where placed was to use the ‘DelegateSentItemStyle’ registry tweak. This had to be done on every single PC where you wanted this to happend, and it was only working for cached Exchange mode.

Then in Exchange 2010 SP2 RU4 we got the new feature to control where to place “Sent Items”. That said, the function has a bug but more about that later.
The cmdlet is Set-MailboxSentItemsConfiguration

Lets make an example:

In this company we have a shared mailbox “Job”. First we check the setting with



Then we change the behaviour for what will happend when the users sends mails as the mailbox “Job”.

Set-MailboxSentItemsConfiguration job -SendAsItemsCopiedTo SenderAndFrom


Now messages sent as this mailbox are saved both in the Sent Items folder of the actual user that sent the message and the Sent Items folder of this mailbox.

I changed this at a customer for 800+ shared mailboxes and what happend? A lot of users called and wanted the mail ONLY to be placed in the “sent items” of the shared mailbox.

Now comes the fun part. You can use the “Set-MailboxSentItemsConfiguration job -SendAsItemsCopiedTo From” – but it doesn’t work. Why? According to inside information this is a bug. If you call Microsoft Support, they will tell you that this is for future use, which is also what you can read at technet in the provided link in the beginning og this post.

But if it was for future use, why should we then be able to use this parameter, and why should it be possible for users to change it in the OWA?


Your next question might be, “what about the deleted items?”. That was what I asked myself. Unfortunately we haven’t got a Set-MailboxDeletedItemsConfiguration neighter in Exchange 2013. You still have to use the registry tweak for that “DelegateWasteBasketStyle

But be careful when using this. You can read my blogpost about this here.

This was my first blogpost – hope you liked it.

I am using a shared mailbox with a disabled account where I get sent items and also deleted items placed in the right folders. I think it’s just a matter of how you configure Outlook. It works well for me in both Outlook 2010 and Outlook 2013. You can add a shared mailbox to your Outlook profile in at least two ways where one of them doesn’t work but the other does. If you add the shared mailbox via the File tab/Account settings/New/ and just enter the e-mail address of the shared mailbox in the Auto Account Setup page. No name, no password, just the e-mail address and click Next and voila “Your e-mail account is successfully configured”. After restarting Outlook you will find the shared mailbox below your own in the left pane. If you click the inbox ones in the shared mailbox and then open a new mail you will see the shared mailbox display name in the From field. After sending the mail you will see the mail in the Sent Items folder of the shared mailbox. If you delete a mail in the shared mailbox you will see it in Deleted items folder of the shared mailbox. The prerequisits for this is that you have “full access” and “send as” rights of the shared mailbox. We are running Exchange 2010 SP3 RU4.
