We are running Office 365 including Exchange.

I've set up a rule to delete messages with attachments with a certain extension, and send a notification to the recipient. This is done with two separate rules - see screenshot:

The question is this: How can I set the sender address that's used for the notification?

Currently these notifications appear to come from one of the managers and we'd like to set it to something neutral.

Run below command to change the sender address for system-generated messages and notifications sent to message senders that exist outside your Microsoft Exchange Online organization.

Set-TransportConfig -ExternalPostmasterAddress manager@domain.com

For more details: Configure the external postmaster address in Exchange Online
