Connect Office 365 to Your Squarespace Domain

To set up custom email addresses using your Squarespace domain with Office 365, follow these essential steps.

Prerequisites:

• Active Office 365 account
• Custom Squarespace domain
• Domain not connected to Google Workspace or other email services

Step 1: Verify Domain Ownership

1. Sign in to your Microsoft 365 account
2. Add a TXT record to your domain through Squarespace's domain dashboard
3. Wait for verification to complete (can take up to 72 hours)

Step 2: Configure DNS Records Add the following DNS records to your Squarespace domain:

• MX records (for email routing)
• CNAME records (for Outlook and other services)
• TXT records (for spam prevention)
• SRV records (for communication services)

Access your domain's DNS settings through:

1. Squarespace Home Menu → Settings → Domains
2. Select your domain
3. Click "Advanced Settings"
4. Add required DNS records following Microsoft's specifications

Important Notes:

• DNS changes may take up to 72 hours to propagate
• Keep existing DNS records unless Microsoft specifically instructs to remove them
• Verify all records are entered exactly as provided by Microsoft
• Test email functionality after DNS propagation

For email migration from other providers to Office 365, consult Microsoft's migration guides for detailed instructions.

Tips:

• Back up existing email data before migration
• Schedule migration during low-traffic periods
• Test email functionality with a small group first
• Keep old email service active until migration is complete
