If we've single domain with 2 different o365 tenants, If I create a contact card for separate o365 tenant , it can't be send out.
400 4.4.7 Message delayed' (Proxy address added SMTP:user@keyman .com)
550 5.2.0 RESOLVER.ADR.MissingPrimary; recipient primary SMTP address is missing (Without SMTP:user@keyman proxy address).
How can I send mail to on-prem contact card to different o365 tenant?
Thanks.
