Question details

Users need a solution for a sign-in loop in the Mover.io transfer wizard that prevents migrating files between Microsoft 365 tenants.

Product: Microsoft 365 / Mover.io
Device & OS: not provided
Scenario: Migrating OneDrive files between school and business Microsoft 365 tenants using the Mover transfer wizard.
Observed behavior: The Mover transfer wizard displays 'Starting application' and immediately returns to the login page, affecting multiple accounts and networks.

Before you start

Verify whether you have administrative access to your Microsoft 365 tenant, as resolving this server-side issue or using alternative official migration tools requires admin privileges.

Solution 1Recommended

Use Microsoft Migration Manager Instead of Mover

Because Mover is officially retired for administrator-led migrations, switching to Migration Manager is the recommended approach for tenant migrations.

Microsoft has retired Mover.io for admin-led tenant-to-tenant migrations. Instead, the native Migration Manager tool in the SharePoint Admin Center provides a more stable, supported experience for migrating data from various sources.

Access the SharePoint Admin Center

Sign in to the Microsoft 365 admin center with your administrator credentials, expand the navigation menu, and select 'SharePoint' under the Admin centers list.

Open Migration Manager

In the left pane of the SharePoint admin center, click on 'Migration' to open the Migration Manager dashboard.

Select Your Migration Source

Choose the appropriate source environment (such as Google Drive, Box, Dropbox, Egnyte, or another Microsoft 365 tenant) and follow the on-screen prompts to connect and initiate your data transfer.

Supported Platforms: Migration Manager fully supports migrations from most major cloud storage providers directly into SharePoint, OneDrive, and Teams.

Solution 2

Manually Transfer Files via Drag-and-Drop

If you are migrating a personal or student account without admin access, you can manually move files between OneDrive locations.

Solution 3

Report the Server-Side Issue to Microsoft Support

Since the sign-in loop behavior affects multiple accounts and networks, it is likely a server-side glitch that requires Microsoft's technical intervention.
