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.
