Configure Alternate Email Domain in GoDaddy Microsoft 365 Tenant

I need an experienced Microsoft 365/Exchange Online administrator to configure an alternate domain in an existing, GoDaddy-managed Microsoft 365 tenant.

**Current environment**

* Primary domain: goodmeasurehomeinspections.com

* Alternate domain: goodmeasurehi.com

* Microsoft 365 purchased and administered through GoDaddy

* One existing licensed mailbox

* DNS records for the alternate domain have already been configured

**Required outcome**

1. Add or verify goodmeasurehi.com as an accepted domain in the same Microsoft 365 tenant.

2. Configure an email alias on my existing mailbox so that email sent to the alternate-domain address is delivered to my primary mailbox.

3. Enable sending from the alternate-domain address, if supported by the GoDaddy-managed tenant and current license.

4. Verify inbound and outbound delivery using both domains.

5. Confirm SPF, DKIM and DMARC alignment and identify any remaining DNS changes needed.

6. Briefly document the final configuration.

This is not a mailbox migration, tenant migration or request for an additional mailbox. I do not want a separate Microsoft 365 tenant created for the alternate domain.

I prefer to perform the work through a screen-sharing session, or by providing a temporary least-privilege administrative account. I will not provide the password to my primary account.

Please include:

* Your experience with GoDaddy-managed/federated Microsoft 365 tenants

* Whether GoDaddy support may need to be involved

* Your fixed-price estimate

* Your expected completion time

This should be a small, focused engagement for someone familiar with Exchange Online and GoDaddy’s Microsoft 365 limitations.
