0100018a4fdb1da4-d67. . . Office 365 jan.hohberger Action Required Recipient SPF validation error

How to Fix It Your organization's email admin will have to diagnose and fix your domain's email settings. Please forward this message to your email admin.

More Info for Email Admins

Status code: 550 5.7.23 This error occurs when Sender Policy Framework (SPF) validation for the sender's domain fails. If you're the sender's email admin, make sure the SPF records for your domain at your domain registrar are set up correctly. Office 365 supports only one SPF record (a TXT record that defines SPF) for your domain. Include the following domain name: spf.protection.outlook.com. If you have a hybrid configuration (some mailboxes in the cloud, and some mailboxes on premises) or if you're an Exchange Online Protection standalone customer, add the outbound IP address of your on-premises servers to the TXT record. For more information and instructions about configuring SPF records see Customize an SPF record to validate outbound mail sent from your domain and also External Domain Name System records for Office 365.
