Not possible in 365.
That command only applies with Edge Servers
https://docs.microsoft.com/en-us/powershell/module/exchange/set-addressrewriteentry?view=exchange-ps

This cmdlet is available or effective only on Edge Transport servers in on-premises Exchange.


365 will rewrite forwarded messages in the following scenarios:

But its not something you can control . Atlassian should send those messages from a legitimate domain with a mx record.

Set-mailbod jira-test@dtn.com -GrantSendOnBehalfTo user@dtn.com



This command did not fix the technical issue we are experiencing when I send an e-mail from the shared mailbox from my Outlook. I was trying to test the shared mailbox to see if it would allow me to send from it.
