Complete Guide to Migrate Google Workspace to Microsoft 365 Account [2026]

Summary: Google Workspace and Microsoft 365 are both enterprise-grade platforms, but they do not share a native migration path. Emails, contacts, calendars, and Drive data all need moving, and none of it transfers automatically. IT teams attempting manual migration hit permission errors, incomplete syncs, and broken folder structure before the process is halfway done. To migrate Google Workspace to Microsoft 365 accurately and at scale, this blog covers one manual method and the MCD Google Workspace Backup Tool as the direct and complete solution.

Pre-Migration Checklist

Before you start the G Suite to Office 365 migration, hit these checkboxes so the migration doesn’t stall:

• Your Office 365 tenant accounts are active, and the domain is verified.
• Exchange Online licenses are assigned to the right users.
• Created users sync correctly with Azure AD.
• APIs are enabled in Google Workspace, and admin access is provided.
• Migration scope and data are predefined (no last-minute surprises).
• Storage limits in O365 are checked, and admin access is granted.

 

How do I migrate Google Workspace emails, contacts, and calendars to Microsoft 365 without losing data?

IMAP sync moves emails but leaves contacts, calendars, and Drive data stuck in Google Workspace entirely. Google Workspace to M365 Migration Tool reads Google Workspace directly and pushes emails, contacts, calendars, and Drive data into Microsoft 365 in one run. Folder hierarchy lands correctly, and bulk accounts process together without repeating any step.

How Do You Migrate Google Workspace to Office 365 Manually?

Manual migration between Google Workspace and Microsoft 365 is possible, but it only works smoothly when each phase is handled in the right order. Most issues don’t come from the migration itself; they come from setup mistakes made earlier. So, we’ll go step by step, just like it’s done in real projects.

Part 1: Check Domain Ownership and User Accounts

1. Sign in to the M365 Admin Center, go to Setup, then pick Domains.
2. Add your Google Workspace domain and the TXT record Microsoft gives you to your domain settings.
3. After that, wait for DNS to propagate, then confirm verification shows success.
4. Moving ahead, head to Users → Active Users.
5. Add or bulk-import all your Google Workspace users.
6. At last, assign each user a proper M365 license that includes Exchange Online.

Part 2: Let Google Workspace Share Data

1. At first, log in to the Google Cloud Console as a super admin.
2. Further, open your Google Cloud Project and then turn on API Scopes for mail, contacts, and drive.
3. After that, create a service account and then enable domain–wide delegation for it.
4. In the Google Admin Console, add the service account email, client ID, and the OAuth scopes.
5. Lastly, wait until Google confirms mailbox access is granted and ready.

Part 3: Migrate from Google Workspace to Office 365

This is the core step: you’ll create endpoints, a CSV list, a migration batch, and run it.

1. In the Microsoft Exchange Admin Center (EAC), click on the Migration option.
2. Choose Add Migration Endpoint, then pick Google Workspace.
3. After that, upload the P12 or JSON key you generated earlier, then finish endpoint creation.
4. Moving ahead, create a CSV file with all user email addresses for the migration batch.
5. Further, back in Migration (EAC), tap on Create Migration Batch.
6. Give it a clear name, and select Migration to Exchange Online as the path.
7. Upload your CSV, then configure any filters you need.
8. Tap on Save and then click Start Migration to begin the transfer.
9. Watch progress in the Migration Dashboard of EAC.
10. When done, update your DNS MX records, then delete the migration batch.

Manual migration is possible, but the setup is not always easy. Each step needs to be checked carefully, as missing even one setting can stop the migration. Many businesses choose easier ways for Google Workspace to Office 365 migration and save time.

Why Some IT Teams Avoid the Manual Route? 

For a small team, the process is usually manageable. The workload grows as more accounts are added. We have covered some limitations below that come along with the manual approach

• User setup must be completed before migration begins.
• API settings need to be checked more than once.
• One incorrect value in a CSV file can create problems.
• Mailboxes do not always move at the same speed.
• Testing migrated data adds another round of work.
• Larger projects become harder to track over time.
