How to intercept emails sent to a specific external email address

[Michael_Nagy]

We have an external provider for document scanning and also one for Email to SMS. But I don't want individuals to send directly to them because I want to manage permissions on those providers by mailbox and not individual user as we have hundreds of users.  I'd also like error messsages to come back to a central point. Is it possible to catch emails being sent by Outlook users to, say,  "*@SomeDomain", and redirect those email to a mailbox. Then I could use Power Automate to send from the mailbox. 

I'm a business user, not an IT Admin so I'm a bit at a loss how to approach the problem. 

Thanks!

Yes, you can use a Mail flow rule for that: https://docs.microsoft.com/en-us/exchange/security-and-compliance/mail-flow-rules/mail-flow-rules
For example, you can use the "recipient is" as condition, and "redirect to" as the action. Or you can add a moderation action, so that you (or someone else) need to approve the message first.

I misread the doco. I took it to mean that a recipient had to be an internal user. Thanks for setting me straight. That's a path forward.
