How to Troubleshoot Google Workspace to Microsoft 365 Migration Server Errors
Question details
Administrators are encountering server errors or stalled batches when migrating users from Google Workspace to Microsoft 365.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Performing a bulk migration of emails, calendars, and contacts from Google Workspace to Microsoft 365.
- Observed behavior
- The migration fails with a server error, halts unexpectedly, or appears complete despite logs being unavailable, often due to API limits or missing configurations.
Ensure you have active Global Administrator privileges for both the Microsoft 365 and Google Workspace admin consoles before proceeding.
Verify Migration Prerequisites and Microsoft 365 Service Health
Check for active Microsoft service outages and ensure all Google Workspace configuration prerequisites are properly met.
Server errors can frequently stem from temporary Microsoft service degradation or missing Google Workspace configurations such as incorrect subdomains or insufficient API permissions.
Log in to the Microsoft 365 admin center, navigate to 'Health', and select 'Service health' to ensure Exchange Online and migration services are fully operational.
In the Google Workspace Admin console, navigate to Security > API Controls and confirm that Microsoft 365 has the necessary domain-wide delegation and read access.
Verify that your routing subdomains are correctly configured in both environments and that email forwarding is properly set up to prevent mail loop errors.
Export Migration Statistics for Detailed Troubleshooting
Use Exchange Online PowerShell to extract detailed error logs for the failing migration batches.

Frequently Asked Questions
Why does my Google Workspace migration appear complete but logs are missing?
This usually happens due to temporary synchronization delays or Google API throttling. The data may have migrated, but the system is waiting to generate and append the final log files to the migration batch.
What is Google API throttling during a migration?
Google Workspace limits the amount of data that can be exported via its API within a 24-hour period (typically around 2GB per user). Once exceeded, Microsoft 365 will encounter a server error until the limit resets.
How do I safely share Get-MoveRequestStatistics reports?
Because these reports contain sensitive user data and environment configurations, you should only share them directly with Microsoft Support via their secure support portal, avoiding public forums or standard email.
