- Your Outlook profile is configured in online mode (not cached Exchange mode).
- You have the DelegateSentItemsStyle registry value set to 1.
Method 1: Change the value of DelegateSentItemsStyle to 0 in the registry.
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.
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.
- Exit Outlook.
- Start Registry Editor. To do this, use one of the following procedures, as appropriate for your version of Windows.
Windows 8 and Windows 10: Press Windows Key + R to open a Run dialog box. Type regedit.exe and then press OK.
Windows 7 or Windows Vista: 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.
Windows XP: Click Start, click Run, type regedit, and then click OK.
- Locate and then select the following registry key:
Note In this key path, the placeholder x.0 represents 16.0 for Outlook 2016, 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.
- Exit Registry Editor.

Microsoft Exchange Server 2010 Service Pack 2 Update Rollup 4 or later:
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.

Because this new feature is handled by the Exchange server, Outlook can be configured for online or cached Exchange mode.
