How to Fix Microsoft 365 Mailbox Marked for Removal After Migration

Product: Microsoft 365
Device & OS: not provided
Scenario: Migrating an email mailbox from a third-party provider like GoDaddy to a Microsoft 365 Business Standard subscription.
Observed behavior: The mailbox is unexpectedly marked for removal after the migration process is completed.

Before you start

Ensure you have administrative access to your Microsoft 365 tenant or know how to contact your organization's IT administrator, as resolving this requires admin privileges.

Solution 1Recommended

Create a Service Request in the Microsoft 365 Admin Center

Use this method if you have direct administrative access to your Microsoft 365 tenant. Microsoft's backend team must investigate and resolve the flag.

Because this issue originates from subscription mapping or backend configuration errors during the migration, it cannot be fixed through standard user settings. Microsoft Support will need to collect diagnostic logs from your tenant.

Log in to the Admin Center

Navigate to the Microsoft 365 Admin Center (admin.microsoft.com) and sign in using your global administrator credentials.

Navigate to Support

On the left-hand navigation menu, click on 'Show all' if necessary, then select 'Support' and choose 'Help & support'.

Open a New Service Request

Type a brief description of the issue (e.g., 'Mailbox marked for removal after GoDaddy migration') in the search bar. Press Enter, review the automated suggestions, and then click the headset icon or 'Contact Support' to open a ticket.

Work with the Backend Team

Provide any requested details or logs to the support agent. They will escalate the ticket to the backend engineering team to remove the deletion flag from your mailbox.

Administrator Required: If you are an end-user, you will not have access to the Admin Center. You must contact your company's IT department to perform these steps.

Solution 2

Contact Your Subscription Reseller

If you purchased your Microsoft 365 subscription through a third-party reseller instead of directly from Microsoft, you must contact them for support.
