Before you start

  1. Have your Microsoft 365 account ready. Some values are unique to your account and come from the Microsoft 365 admin center.
  2. Open DNS at Bluehost: Log in to the Bluehost Portal and click Domains in the left-hand menu. Select your domain, then open the DNS tab.
  3. Keep both tabs open and add the records below one at a time.

Records to add

Copy each value with the button next to it. Rows marked “Copy from Microsoft 365 admin center” are unique to your account.

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

  • This record only proves you own the domain. It doesn't affect anything else and can be deleted after verification.
  • Verification usually takes up to 10 minutes after adding the record, sometimes up to 48 hours.

In Bluehost

  1. On the DNS tab, click + Add Record and select Single Record.
  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

Point your MX records

MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.

Type
MX
Host Record
@
Priority
0
Points to
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

  • Use the highest priority your host allows, typically 0.
  • 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.
  • Exchange Online only supports TTL values under 6 hours (21,600 seconds).

In Bluehost

  1. Under the DNS tab, go to Manage Advanced DNS Records and click Add Record.
  2. Set Type to MX. Type @ in Host Record, enter the mail server in Points to, and set the Priority. Leave TTL at its default.
  3. Save the record.

Add the SPF record

SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.

Type
TXT
Host Name
@
TXT Value
v=spf1 include:spf.protection.outlook.com -all
  • If an SPF record already exists, don't create a second one. Add include:spf.protection.outlook.com to the existing record so there is a single SPF record.
  • Microsoft recommends -all (hard fail) together with DKIM and DMARC.
  • Only one SPF record is allowed per domain, and it must stay under 10 DNS lookups.

In Bluehost

  1. On the DNS tab, click + Add Record and select Single Record.
  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

Set up DKIM (recommended)

DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.

Type
CNAME
Host Record
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)

  • Microsoft lists DKIM as optional, but DMARC needs DKIM to align with your domain.
  • 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.

In Bluehost

  1. Under the DNS tab, click Add Record.
  2. Set Type to CNAME, enter the name, and put the target hostname in Points to.
  3. Save the record.
  4. Repeat for each CNAME record above.

Add the DMARC record (recommended)

DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.

Type
TXT
Host Name
_dmarc
TXT Value
v=DMARC1; p=none; pct=100; rua=mailto:dmarc@yourdomain.com
  • Start with p=none and read the reports, then move to p=quarantine and finally p=reject. pct can step up in stages (10, 25, 50, 75, 100).
  • Replace the report address with a shared mailbox or group, not a personal inbox.
  • Set up SPF and DKIM first.
  • Microsoft 365 doesn't send forensic (ruf) reports.

In Bluehost

  1. On the DNS tab, click + Add Record and select Single Record.
  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

Add the Autodiscover record (recommended)

Autodiscover lets Outlook and other mail apps find your account settings without manual setup.

Type
CNAME
Host Record
autodiscover
Points to
autodiscover.outlook.com
  • Optional but highly recommended: lets Outlook and other apps set up mailboxes automatically.

In Bluehost

  1. Under the DNS tab, click Add Record.
  2. Set Type to CNAME, enter the name, and put the target hostname in Points to.
  3. Save the record.

Check your setup

Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in Bluehost’s words.

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.

Publishing DKIM CNAMEs but not turning on signing

After both selector CNAMEs resolve, switch on Sign messages for this domain with DKIM signatures in the Defender portal.

Using a TTL longer than 6 hours on MX

Exchange Online only supports TTL values under 6 hours (21,600 seconds). One hour (3600) is the recommended value.

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.

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.

Where do I get my Microsoft 365 DKIM record?

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).

How long until Microsoft 365 email works on Bluehost?
