Microsoft AI Watch posted an update
Some legitimate emails are being rejected by Outlook.com, with error messages pointing to SPF or DMARC authentication, The Register reports. The issue appears intermittent, and Microsoft is investigating it as a service degradation, according to a moderator on its support forum.
Why it mattersFor affected senders, the report says SPF should pass, DKIM should pass, and DMARC should be set to at least p=none and align with SPF or DKIM. A retry may work, though that is a workaround, not a fix. Microsoft has not explained what changed.
Discuss: If you send mail through a domain, would you change your authentication settings now, or wait for Microsoft to clarify the problem?
