This article contains information about how to modify the registry. Make sure that you back up the registry before you modify it.

How to back up and restore the registry in Windows
This problem occurs when all the following conditions are true:
- Your Outlook profile is configured in online mode (not cached Exchange mode).
- You have the DelegateSentItemsStyle registry value set to 1.
Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
There is no resolution to this problem other than to either switch your profile to cached Exchange mode or set the DelegateSentItemsStyle registry value to zero (0). Additionally, if your mailbox is located on Microsoft Exchange Server 2010 (or later), the Exchange administrator can configure similar behavior on the server.Note
If you set DelegateSentItemsStyle=0 in the registry, email messages that you send from a shared mailbox will be copied to your
Sent Items folder and not the Sent Items folder of the shared mailbox.
- Change the value of DelegateSentItemsStyle to 0 in the registry
To change the value of DelegateSentItemsStyle to 0 in the registry, follow these steps:
- Exit Outlook.
- Start Registry Editor.
In Windows 8 and Windows 8.1
Swipe in from the right to open the charms, tap or click Search, and then type regedit.exe in the search box. Or, type regedit.exe at the Start screen, and then tap or click regedit in the search results.
In Windows Vista and Windows 7
Click Start, type regedit in the Start Search box, and then press Enter. If you are prompted for an administrator password or for confirmation, type the password, or click Allow.
In Windows XP
Click Start, click Run, type regedit, and then click OK.

Note In this key path, the placeholder x.0represents 15.0 for Outlook 2013, 14.0 for Outlook 2010, 12.0 for Outlook 2007, and 11.0 for Outlook 2003.
- Select the DelegateSentItemsStyle value.
- On the Edit menu, click Modify.
- Type 0, and then click OK.

Update Rollup 4 for Exchange Server 2010 Service Pack 2 introduced a new Exchange PowerShell cmdlet to configure the Sent Items folder to which a message is copied. Because this new feature is handled by the Exchange server, Outlook can be configured for online or cached Exchange mode. However, the Exchange server feature works only if the Outlook DelegateSentItemsStyle registry value is disabled.
