De klassieke versie van Outlook voor Windows gebruiken voor het beheren van persoonlijk e-mail en agenda en contacten
Hello,
Why is that necessary?
Yes, this is a recommended troubleshooting step from Microsoft.
Here is some background - Microsoft now requires SPF and DKIM records for each domain. If they aren't there, the email won't be recieved.
SPF and DKIM are checks that help Microsoft confirm an email really came from the domain in the sender address. SPF lists approved mail servers; DKIM adds a digital signature. These checks make it harder for scammers to impersonate people or organizations.
If someone isn’t receiving an email, the sender’s domain may be missing or misconfigured on these checks, so Microsoft could send it to Junk or reject it. The sender’s IT team or email provider may need to fix the settings.
