Finally! Sent Items behaviour control for User mailboxes in Exchange CU6.

From Exchange 2016 CU6 and for Exchange Online customers it is now possible to control the “Sent Items” behaviour of delegated User Mailboxes. This control is available for shared mailboxes since 2015.

How does it work?

Let’s say you have the following scenario:

  • Jack is the CEO of the company
  • Iris is a delegate on Jack’s mailbox; Iris has Send As rights on Jacks mailbox
  • When Iris sends an email as Jack, the mail will only be in Iris’s “Sent Items” folder.

With the new feature enabled, the email will not only be in Iris’s “Sent Items” folder but both Jack and Iris will have the message in their “Sent Items” folder.

How to enable these settings?

These settings have to be set via powershell and cannot be set via the EAC / o365 portal as with shared mailboxes.

To enable these settings for “Sent On behalf”:

Enable message copySent On Behalf of the delegator For emails Sent On Behalf of the delegator:

Set-Mailbox <delegator mailbox name> –MessageCopyForSendOnBehalfEnabled $true

Disable message copySent On Behalf of the delegator For emails Sent On Behalf of the delegator:

Set-Mailbox <delegator mailbox name> –MessageCopyForSendOnBehalfEnabled $false

To Enable these settings for “Sent As”

Enable Message copy:

Set-Mailbox <delegator mailbox name> –MessageCopyForSentAsEnabled $true

Disable Message copy:

Set-Mailbox <delegator mailbox name> –MessageCopyForSentAsEnabled $false
