Microsoft 365 groups – Do you receive a copy of your own email into your inbox?

Microsoft 365 groups - When anyone sends an email to a Microsoft 365 group (Office365 groups) e.g: SysAdmins@Northwind.com they don’t receive a copy of their own email, which is different from normal distribution groups.

To change the behavior the user can use the checkbox Outlook | Settings | Additional Settings | Groups | ‘Send me a copy of the email I send to a group’.

Note: This can be enabled on the server side by doing a PowerShell script. This feature is turned on by default. Users can turn it off manually using the above steps to not receive a copy of a email sent to a Microsoft 365 group.
