Microsoft Support

Try this before escalating to Microsoft support:

1. Use the Microsoft 365 Admin Center

Since you're working with a business subscription, support is available through the admin portal:

• Go to admin.microsoft.com
• Sign in with your Microsoft 365 Business Basic admin account
• Click Help & Support in the bottom-right corner
• Type your issue and select the headset icon to contact support directly

If you're using a personal account, you won’t have access to business support. You’ll need to sign in with the account that holds the Business Basic subscription.

2. Set Up Your Domain and Exchange Mailbox

• Follow the steps in the Business Basic setup guide
• If you're adding a custom domain, use the Add a domain guide

These guides walk you through:

• Purchasing or connecting a domain
• Verifying ownership
• Setting up DNS records
• Assigning licenses and creating mailboxes
