Email on your domain / Microsoft 365
Microsoft 365 on your domain. The exact records.
The DNS records Microsoft 365’s own docs ask for, so mail to you@yourdomain arrives and what you send isn’t marked as spam. Add them at your domain’s DNS provider, then check your domain live below.
Add these records at your DNS provider
“@” means the domain itself. MX records receive mail; SPF, DKIM and DMARC prove that mail you send is really yours.

Microsoft gives each domain its own MX host and DKIM targets. Copy them from the admin center: Settings → Domains → your domain → DNS records.
A domain can have only one SPF record. If your app also sends email through another service, the two must be merged into one: add the service below and the check gives you the merged record.
Check your domain
Type your domain: we read public DNS and show which Microsoft 365 records are in place, which are missing and which need to change.
