📧 Automatically save sent items to your personal and shared mailbox in Office 365

When you send an e-mail from a shared mailbox, it defaults to the user who sent the e-mail. This can be annoying, especially if you also want to receive the mail in the shared mailbox. Fortunately, it is possible to solve this by automatically copying the mail to the shared mailbox.

In the past, this was sometimes done using a GPO (Group Policy Object). But nowadays it is convenient to have this feature available on all devices, regardless of whether you use a PC or a mobile device to send mail. By automatically copying the mail to the shared mailbox, you can always access it from any device.

Manual adjustment in the Microsoft 365 Admin Center

  • Open your admin portal from Office 365 or go through the URL page.
  • Navigate to shared mailboxes, under Teams & Groups.
  • Search for the desired mailbox
  • Click on sent items
  • Edit
  • Select "Copy items sent from this inbox"
  • Click save.

Script for all mailboxes

To automatically save sent items to your personal and shared mailbox, you can run this script for all Office 365 mailboxes within Exchange Online.

Login with PowerShell at Exchange Online . See also other blogs on Powershell

Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'SharedMailbox')} | set-mailbox -MessageCopyForSentAsEnabled $True
