Step by step in Bluehost

Verify your domain

Your email provider needs proof that you control this domain before it accepts email for it.

Type
TXT
Host Name
@
TXT Value
Copy it from Microsoft 365 admin center (see below)

Where to find your value

In the Microsoft 365 admin center go to Settings > Domains and add your domain (or select it and choose Start setup). On Verify you own your domain, choose Add a TXT record to the domain's DNS records and copy the TXT value.

It looks like: MS=ms followed by digits

  • Verification usually takes up to 10 minutes after adding the record, sometimes up to 48 hours.

Copy it from Microsoft 365 admin center (see below)

Where to find your value

In the Microsoft 365 admin center go to Settings > Domains, select your domain, then DNS records > Manage DNS. On the Add DNS records page, expand MX Records and copy the value.

It looks like: <your MX token>.mail.protection.outlook.com, or for domains set up on Microsoft's newer DNSSEC infrastructure <your MX token>.<subdomain>.mx.microsoft

  • Remove MX records that point to your previous email provider, or give them a lower priority (a higher number) than the Microsoft 365 record.
  • Add users and mailboxes in Microsoft 365 before switching the MX record so incoming mail keeps flowing.

selector1._domainkey
Points to
Copy it from Microsoft 365 admin center (see below)

Where to find your value

In the Microsoft Defender portal open Email authentication settings (security.microsoft.com/authentication), select the DKIM tab and your domain, then copy the two CNAME values. They are also shown in the admin center under Add DNS records > Advanced options > DomainKeys Identified Mail (DKIM).

It looks like: selector1-yourdomain-com._domainkey.<your onmicrosoft prefix>.<letter>-v1.dkim.mail.microsoft (older domains: selector1-yourdomain-com._domainkey.<prefix>.onmicrosoft.com)

  • After both CNAME records resolve, turn on Sign messages for this domain with DKIM signatures in the Defender portal.
Type
CNAME
Host Record
selector2._domainkey
Points to
Copy it from Microsoft 365 admin center (see below)

Where to find your value

Same place as selector1: Defender portal > Email authentication settings > DKIM tab > your domain.

It looks like: selector2-yourdomain-com._domainkey.<your onmicrosoft prefix>.<letter>-v1.dkim.mail.microsoft (older domains: selector2-yourdomain-com._domainkey.<prefix>.onmicrosoft.com)

  • Add both selector records. Microsoft rotates between them.

We only read public DNS records. Nothing is stored.

Common mistakes with Microsoft 365 on Bluehost

Switching MX before adding mailboxes

Add users and mailboxes in Microsoft 365 before changing the MX record, or incoming mail has nowhere to go.

Adding a second SPF record

Microsoft says not to create a new SPF record if one exists. Add include:spf.protection.outlook.com to the existing record so there is a single SPF record.

Bluehost: Replace Bluehost's default MX record

By default Bluehost's MX record points to your own domain, which delivers mail to Bluehost's local server. Change it to your provider's mail server.

Bluehost: Set email routing to Remote

If Bluehost doesn’t host your email, change the domain’s email routing setting to Remote. Otherwise Bluehost keeps treating mail for the domain as local.

Microsoft 365 on Bluehost: questions

Will my old Bluehost emails disappear when I switch to Microsoft 365?

No. Bluehost says new mail is delivered to the new provider, and messages already in Bluehost mailboxes stay there unless you move or remove them.

Where do I add Microsoft 365 DNS records in Bluehost?

Log in to the Bluehost Portal and click Domains in the left-hand menu. Select your domain, then open the DNS tab. Add each record there, one at a time.

What goes in the Host Record field at Bluehost?

Enter @ for records on your bare domain, such as MX and SPF. For the others, enter autodiscover.

Do I need to delete my existing MX records at Bluehost?

Remove MX records that point to your previous email provider, or give them a lower priority (a higher number) than the Microsoft 365 record. By default Bluehost's MX record points to your own domain, which delivers mail to Bluehost's local server. Change it to your provider's mail server. If Bluehost doesn’t host your email, change the domain’s email routing setting to Remote. Otherwise Bluehost keeps treating mail for the domain as local.

How long until Microsoft 365 email works on Bluehost?

DNS changes typically take about 15 minutes to take effect, occasionally longer. Bluehost says saved changes are processed in a few minutes but can take up to 8 hours to fully propagate, depending on caching and TTL.
