Sender Rewriting Scheme (SRS) Expanding to SMTP/Mailbox Forwarding
Microsoft is set to roll out a change in mid-August to SMTP forwarding from mailboxes in Exchange Online that will result in messages being rewritten with Sender Rewriting Scheme (SRS). Previously, messages forwarded via SMTP or mailbox forwarding would have their P1 Mail From address replaced with the forwarding mailbox address. With this change, SRS rewriting will be used instead. The rollout is expected to be completed by late October. Recipients of messages will see the P2 From address of the original sender, while on-premises email servers configured to act on the P1 Mail From address could be negatively impacted. To prepare, on-premises connectors can be enabled to enable SRS rewriting for impacted messages. For the most part, the risk of any impact on forwarded messages should be low.
