In General it is not possible to forward an email to multiple addresses.

This command can be used to set forwarding email by an administrator:

Set-Mailbox -Identity “” -DeliverToMailboxAndForward $true -ForwardingSMTPAddress

But this command does not accept more than one email so in case of a need to forward to multiple addresses either we need to create a distribution group to use its email as forwarding address or another way is to use inbox rules e.g.

New-InboxRule “Forward to Multiple Emails” -Mailbox -RedirectTo @(‘’,’’)
