but the sent is not in any sent item of the shared mailbox or even my sent items my outlook is not in cached mode cause we don't have big disk to keep them

Hi @POJ ,

we try to implement a reg file DelegateSentItemsStyle value of 1

Outlook must be configured to run in cached mode for this option to work properly.

According to my research and test, it works when I run the command via PowerShell.

For message Sent As a mailbox;

Set-Mailbox <mailbox name> –MessageCopyForSentAsEnabled $true

For messages Sent on Behalf of a mailbox;

Set-Mailbox <mailbox name> –MessageCopyForSendOnBehalfEnabled $true

Note: For the server-side method to work, the client-side method with the DelegateSentItemsStyle Registry key must be removed.
