- Scenario
- Setting up business email hosting on Microsoft 365 using a custom domain currently managed by Weebly.
- Observed behavior
- The user needs the correct procedure to verify domain ownership and configure MX, SPF, and Autodiscover records in Weebly without breaking the existing website.
Ensure you have an active Microsoft 365 Business or Exchange Online subscription and possess administrator login credentials for both your Microsoft 365 Admin Center and your Weebly dashboard.
Configure Weebly DNS Records for Microsoft 365
Follow these steps to verify your domain ownership and point your email services to Microsoft 365 without affecting your Weebly website.
To route your custom domain's emails through Microsoft 365, you must prove domain ownership via a TXT record, create your mailboxes, and then update specific DNS records (MX, SPF, and CNAME) within Weebly's control panel.
Sign in to the Microsoft 365 admin center, navigate to Settings > Domains, and click on 'Add domain'. Enter your Weebly domain name and select 'Use this domain'.
Microsoft will generate a specific TXT record for verification. Log in to your Weebly account, go to the Domains page, click on your domain, and access the DNS settings. Add the provided TXT record and return to Microsoft 365 to click 'Verify'.
Once the domain is verified, use the Microsoft 365 admin center to create new user accounts and mailboxes that utilize your custom domain name.
Return to Weebly's DNS settings. Add the MX record (for mail routing), the SPF/TXT record (for spam prevention), and the Autodiscover CNAME record exactly as provided by Microsoft 365. Do not modify or delete any A records associated with your website.
Open the Outlook desktop application, click on File > Add Account, and enter your new custom domain email address. Outlook will use the Autodiscover record to configure the connection automatically. Send a test email to verify.

Frequently Asked Questions
Will changing DNS records for Microsoft 365 affect my Weebly website?
No, as long as you only modify or add the email-specific records (MX, TXT/SPF, and Autodiscover CNAME). Leave the A records and nameservers pointing to Weebly to ensure your website stays online.
Can I use Microsoft 365 Family for a custom domain on Weebly?
No, Microsoft removed custom domain support for Microsoft 365 Personal and Family plans. You must subscribe to an Exchange Online or Microsoft 365 Business plan to host business emails on a custom domain.
How long does it take for the Weebly DNS changes to take effect?
DNS propagation typically takes anywhere from a few minutes to 48 hours. If Microsoft 365 cannot verify the records immediately, wait an hour and try clicking the 'Verify' button again in the admin center.
