  • the instructions apply only if you have full access permissions to a mailbox you want to send emails from.

    The x.0 depends on your Outlook version: 16.0 = Outlook 2016, 15.0 = Outlook 2013, 14.0 = Outlook 2010
  3. Right-click on Edit menu, navigate to New > DWORD Value
  4. Type DelegateSentItemsStyle, press Enter
  5. Double-click DelegateSentItemsStyle, type in 1 in the Value Data box, click OK
