How to block auto forwarding of emails from Microsoft flow



We have set transport rule on exchange server(we have hybrid infrastructure exchange online & On-prem) which blocks auto forwarded emails through outlook inbox rules and OWA to the external email account. This is fine and as expected.

But when we use Microsoft flow for auto-forwarding of emails to the external accounts, these emails are not being blocked through server. And we are not able to understand why?


And don't know how to stop auto-forwarding of emails to external account through Microsoft flow.

We have checked article "", but this is not feasible since API needs global admin access.


Any thoughts?


HI @rajp,


How are you autoforwarding the the emails using flow?


Are you going through thesee steps:

- Read content of email

- Create new email with Send an Email
