I need to speak to a live person about my Windows 365 license and Microsoft 365 email migration

Sign in as a Microsoft 365 administrator and open two separate support requests—one for the Windows 365 licensing issue and another for the Microsoft 365 email migration—then request a callback from each case.

Contact business support

1. Sign in to the Microsoft 365 admin center using an administrator account.
2. Select Help & support in the lower-right corner.
3. Enter a description such as:
   • Case 1: “Windows 365 licensing and billing assistance”
   • Case 2: “Microsoft 365 email/mailbox migration assistance”
4. If the suggested articles do not resolve the issue, select the Contact Support headset icon.
5. Choose Phone or Email, confirm your contact details, and select Contact me. The pane displays the expected wait time.

Microsoft recommends opening separate cases for separate issues, and this administrator support route requires at least one subscription purchased directly from Microsoft.^1^

Have these details available for the agents:

• Tenant or organization name
• Windows 365 subscription and affected user information
• Where the email is being migrated from
• Number of mailboxes
• Migration method and any exact error messages
• Desired migration date and current business impact

If that route is unavailable

• Subscription purchased through a reseller or partner: Contact that partner directly. Microsoft’s business-support documentation says organizations whose subscriptions were all purchased through a partner must obtain support from the partner.^1^
• Not a Microsoft 365 administrator: Ask the business owner or Microsoft 365 administrator to open the cases. Business support methods in the admin center require an administrator. Alternatively, use the public Microsoft Support contact page.^1^
• Need to call directly: Use Microsoft’s current country/region phone list. Billing support hours vary by region; English-language technical support is available 24/7. Keep the organization’s registered email or phone accessible because support may send a PIN for account verification.^1^
• General contact flow: Microsoft’s support page can route account, billing, and technical requests to available options, which may include live chat.^2^

Do not post tenant IDs, license keys, invoices, email addresses, or migration credentials in this public Q&A forum.
