Redirect (user OWA rule) does not work

I need to do redirect on one mailbox (so the headers are preserved)

Redirect to EXTERNAL domain

But the rule does not seem to kick in at all.

email comes to user's mailbox, but the redirect to external domain does not happen at all

I did set that remote domain as per: https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/remote-domains/manage-remote-domains

with all allow

Yet still only get failure:

Reason: [{LED=250 2.1.5 RESOLVER.MSGTYPE.AF; handled AutoForward addressed to external recipient};{MSG=};{FQDN=};{IP=};{LRT=}]

Thanks
