Set up your domain to use email inboxes in Office 365

To use Microsoft Office 365 email services with a domain managed in the mybox panel, you need to configure DNS records correctly. These records verify domain ownership and route email traffic to Microsoft’s mail servers.

Before starting, ensure that the domain is correctly added and verified in your Office 365 admin panel.

Step 1: Add domain in Office 365

1. Log in to the Office 365 admin dashboard
2. Go to Settings → Domains
3. Click + Add domain
4. Enter your domain name and continue

Office 365 will generate a verification record (TXT) that must be added to your DNS zone.

Example:

• TXT name: @
• TXT value: MS=ms01234567
• TTL: 3600

Step 2: Add TXT verification record in the mybox panel

1. Log in to the mybox panel
2. Go to Domains
3. Select your domain
4. Open the Parked tab
5. Click Manage DNS
6. Add a new TXT record using the values provided by Office 365

This confirms domain ownership.

Step 3: Configure Office 365 DNS mode

In Office 365:

• select I manage my DNS records
• continue to the next step to retrieve required DNS entries

Step 4: Configure MX record

Add the MX record provided by Office 365 in the mybox panel.

Example:

your-domain.com MX 0 your-domain.mail.protection.outlook.com 900

After adding the MX record:

• remove existing mail-related MX records from mybox to avoid conflicts

Step 5: Add required CNAME records

Typical Office 365 CNAME records include:

• autodiscover → autodiscover.outlook.com
• sip → sipdir.online.lync.com
• lyncdiscover → webdir.online.lync.com
• enterpriseregistration → enterpriseregistration.windows.net
• enterpriseenrollment → enterpriseenrollment.manage.microsoft.com

Step 6: Add SPF record

SPF helps prevent email spoofing.

Example:

v=spf1 include:spf.protection.outlook.com -all

Step 7: Add SRV records

Office 365 may require SRV records for communication services:

Example:

_sip._tls SRV 1 443 sipdir.online.lync.com
_sipfederationtls._tcp SRV 1 5061 sipfed.online.lync.com

Step 8: Verify domain in Office 365

After all DNS records are added:

• return to the Office 365 admin panel
• click Verify

If verification fails:

• wait for DNS propagation (can take several minutes to a few hours)

Practical implications

Correct DNS configuration ensures:

• email delivery through Microsoft servers
• proper Outlook and mobile device synchronization
• domain ownership validation
• secure email authentication

Summary

To use Office 365 email with a domain in the mybox panel, you must verify domain ownership and configure DNS records (TXT, MX, CNAME, SPF, and SRV). After propagation, Office 365 will activate email services for the domain.
