The user needs to resolve an account conflict where a single GoDaddy-purchased email address connects to two completely different Microsoft 365 mailboxes depending on the client used.

How to Fix One Email Address Opening Two Different Microsoft 365 Mailboxes
Product
Microsoft 365 / GoDaddy Email
Device & OS
Mac OS
Scenario
Accessing a Microsoft 365 mailbox purchased through GoDaddy on different email clients like the web portal and Mac Mail.
Observed behavior
Logging in through the GoDaddy portal opens the correct populated mailbox, but using the same address in Microsoft 365 or Mac Mail opens an almost empty mailbox, suggesting two separate identities or tenants exist.
Before you start

Ensure you have your GoDaddy account login credentials ready and take note of the exact server settings currently configured in your Mac Mail application before making changes.

Solution 1Recommended

Contact GoDaddy Support to Verify Tenant Configuration

Since the email service is managed through GoDaddy, their support team must verify if the address is associated with multiple Microsoft 365 tenants or identities.

When an email service is purchased through a third-party provider like GoDaddy, they act as your Microsoft 365 administrator. Account conflicts often occur when a personal Microsoft account and a work account share the same email address.

1
Log into GoDaddy

Navigate to the GoDaddy website and log in to your account dashboard using your primary credentials.

2
Access Support

Navigate to the 'Help' or 'Contact Us' section to initiate a chat or phone call with a GoDaddy support representative.

3
Explain the Issue

Inform the agent that your single email address is accessing two separate Microsoft 365 mailboxes (one populated, one empty) depending on the login portal.

4
Request Identity Verification

Ask the support agent to verify your mailbox configuration and check if the email address is associated with separate identities, tenants, or conflicting mailboxes on their end.

Contact GoDaddy Support to Verify Tenant Configuration
Check Microsoft 365 Identities: If GoDaddy support cannot resolve the issue directly, ask them to escalate the ticket or consult the Microsoft 365 Q&A community regarding conflicting 'Personal' and 'Work/School' identities.

Frequently Asked Questions

Why does my GoDaddy Microsoft 365 email show up as two different accounts?

This typically occurs if a personal Microsoft account and a business/tenant account were created using the exact same email address. The authentication systems may route you to different mailboxes depending on which login portal or client you use.

How do I ensure Mac Mail connects to the right GoDaddy mailbox?

When adding the account in Mac Mail, always select the 'Exchange' option. Make sure you are redirected to the GoDaddy-branded login page during the authentication step. If it authenticates directly through Microsoft without GoDaddy branding, it might connect to the wrong tenant.

Can I merge the two conflicting Microsoft 365 mailboxes?

No, you cannot directly merge two separate Microsoft 365 identities or tenants. You must manually move or forward any necessary emails from the incorrect mailbox to the correct one, and then ask support to delete the duplicate identity.

Who should I contact for GoDaddy email issues: Microsoft or GoDaddy?

Because your Microsoft 365 license was purchased through GoDaddy, they act as your primary administrator. You must contact GoDaddy support first to resolve account setup and tenant configuration problems.
