I've only been able to find an answer for this problem for Outlook 2010, and that doesn't work for 2013.

I'm trying to make the sent items for a shared mailbox save to the sent items of that mailbox, not my mailbox.  I got the deleted items to finally work, I just need to get the sent items to work now. 

I've read about this key:

HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Options\Conversations

But I don't have the conversations folder, should I make it?

I've also seen this:

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Preferences\DelegateSentItemsStyle

But that doesn't seem to work with Office 2013.

Any ideas?

Thanks

Hi,

The registry key DelegateSentItemsStyle works with Office 2013. Just locate HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences, create the registry key DelegateSentItemsStyle, and set the value to 1.

Value name: DelegateSentItemsStyle
Value Type: REG_DWORD
Value: 1

Note: we need to restart Outlook to make it work.

For more information, please refer:

Hope this helps.

I made this registry change but it still isn't working.  I restarted Outlook, rebooted, and tried cached exchange mode.  Are there any other settings that it would need?

Alternatively you can use this tool: U

I was looking at this, but I'd need to deploy it to ~200 people.  Seems like a lot of work and money to fix a Microsoft bug. 

There exists also a server based tool with the same functionality: CentralUniSent.

We have the same problem with a client. We are using Office 365 with Outlook 2013 on a RDS Windows Server 2012 R2. I can't find the HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Preferences folder in the registry. HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\ is as far as it gets.

Even when we sent from the Office 365 online mailbox and fill in the from address, the sent mail is stored in the sent items folder from the user instead of the shared mailbox.

I've searched everywhere for a solution, but I haven't found one yet.

Has anyone found a solution for this? I have a number of Office365 shared mailboxes and sent items are being stored in the personal sent items for a user instead of the shared mailbox sent items.

I have tried the adding the registry key suggested here but it just keeps the email in the personal 'outbox' of the users account. The email does get delivered but the email just sits in the outbox. Users are either using Outlook 2010 or 2013 same issue on both.

Hi all,

yes users have 'send as' permissions on the mailbox. Figured out what I was doing wrong. The user mailboxes were in 'online mode'. Once I changed it to 'cached Exchange mode' with the reg key entry in place Outlook started to put the sent items into the sent items folder of the shared mailbox. So 'Cached Exchange Mode' and the reg key did the trick...

Hi,

Thanks for this key. It works.

Microsoft has had this bug (this is a bug, who would ever want to keep sent e-mails in the wrong account??) for decades now. With IMAP accounts, you can specify the sent directory (since outlook 2007), but you can't with exchange accounts. That's a bit crazy.

Now, what can we do to get deleted items go in the correct directory as well??? same with drafts (provided the sender is not our default account when the draft is saved) ??

Regards,

The deleted key is

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Options\General
DWORD: DelegateWastebasketStyle
Value: 4 (use shared mailbox's Deleted items)

From: http://www.slipstick.com/exchange/shared-mailboxes-deleted-items-folder/

There isn't a key for drafts that I recall.

If you add the account as an Exchange account, not as a shared mailbox, the correct folders are used. You can't compare Exchange and IMAP accounts - they have different security features available. IMAP accounts can (or could, some servers no longer allow it) send as any address they want, just by typing an address in the from field but Exchange will reject it if you don't have permission to send using that address.

Alternatively you can use this tool: UniSen

Have you tried recreating new outlook profile?

If the key doesn't exist, you need to add it yourself.  However, a sever-side solution is available in Office 365 (and it doesn't work right if the key is set) Check with your admin and see if it's enabled.  More info: https://community.office365.com/en-us/b/office_365_buzz/archive/2015/03/03/want-more-control-over-sent-items-when-using-shared-mailboxes
