Why Isn't Microsoft Recognizing My CNAME Records for DKIM?
Asked by

I'm setting up email for my business with a custom domain and trying to include DKIM verification. I've added the specified CNAME records to my DNS, but when I try to activate it, I keep getting this error: "CNAME record does not exist for this config." The CNAME records I need to add are:
- Domain Name: advorex.com
- Host Name: selector1._domainkey pointing to selector1-advorex-com._domainkey.Advorex.w-v1.dkim.mail.microsoft
- Host Name: selector2._domainkey pointing to selector2-advorex-com._domainkey.Advorex.w-v1.dkim.mail.microsoft
The error message mentions it could take up to 4 days for the records to sync, but I've heard it shouldn't take that long. I'm not a tech whiz, so any help you could provide would be appreciated! Just to clarify, I did spot a typo in the values, but would still love some insight on the timing of DNS updates.

Always double-check! If you typed them out, maybe use copy/paste next time. I've seen with tools like Dig, it looks like your records are incorrect—there’s a difference between what you think is there vs. what’s actually published.

It sounds like you've got a small error in your CNAME values. From checking what you've posted, I think the issue might be with a dash instead of a dot in the value. You should have it end in .w-v1.dkim.mail.microsoft instead of -w-v1.dkim.mail.microsoft.

TechWizard92: Thanks for the tip! I thought I copied everything correctly, so it’s weird that there’s a dash instead of a dot. I'll double-check those records.
