Summary: Migrating data from G Suite to Office 365 Archive Mailbox can be challenging using manual methods due to limitations and potential errors. Kernel G Suite to Office 365 simplifies the process by offering a user-friendly interface and powerful filtering options. This tool ensures a seamless transition, transferring complete mailbox content, permissions, and metadata, making it an ideal solution for organizations looking to migrate their G Suite data to Office 365 Archive Mailbox.

When comparing the advantages of G Suite (now known as Google Workspace) and Microsoft 365, Microsoft 365 is often favored for its business-friendly applications. If you’re considering migrating to Microsoft 365, you can do so through the Exchange Admin Center. Here’s a step-by-step guide on how to accomplish this.

Migrate G Suite Data to Microsoft 365 Mailbox Manually

Stage 1. Verify the Google Domain

Before initiating the migration through the Exchange Admin Center, it’s essential to confirm ownership of the Google Workspace domain that you intend to transfer to Microsoft 365.

When configuring Microsoft 365 to handle data from Gmail, the setup wizard will supply you with a TXT record that needs to be added to your domain host provider. If you’ve purchased your domain directly from Google, they serve as the domain host provider, allowing you to add the TXT record through their platform.

If you obtained your domain from a third-party company, you should follow their specific procedure for adding the TXT record.

Stage 2. Add New Users

You must create user accounts in the Microsoft 365 Admin Center, where you can add users individually or in bulk. Each user will receive a mailbox along with an Exchange Online license.

Stage 3. Create User List in Google Workspace Admin Control

To create a migration file in MS Excel, you’ll need to have information about Workspace accounts, including email addresses and passwords for Google accounts.

  1. Login to Google Workspace Admin Console and go to the active users‘ list.
  2. Note down the email address of such users that you want to migrate.
  3. Open MS Excel and input EmailAddress, UserName, and Password fields in separate columns.
    Create User List in Google Workspace Admin Control
  4. After inputting the details of the account, save the Excel file as a comma-separated value file (CSV).

Stage 4. Create Migration Endpoints

Migration Endpoint connects Microsoft 365 with a Google account. Do the following steps-

  1. Login to Exchange Admin Center.
  2. Follow Recipients >> Migration >> More (…) >> Migration Endpoints.
  3. Click the New (+) button.
  4. On the Migration Endpoint page, choose IMAP.
  5. Set IMAP server as imap.gmail.com and keep the remaining settings the same.
  6. Provide a new name to the Migration endpoint and click New to create it.

Stage 5. Create the Migration Batch

The migration batch can add the earlier created CSV file and migration endpoint to start the migration of Google accounts to Microsoft 365.

  1. In Microsoft 365 Admin Center, go to Exchange.
  2. Follow Recipients >> Migration >> New (+) >> Migrate to Exchange Online.
  3. Select IMAP Migration, click Next, browse the migration file that you have created.
  4. After selecting the migration file, select the migration endpoint, accept the default values, and click Next.
  5. Click Add and provide a new name to the migration batch. Click Next and start the migration.
  6. On the migration page, you can see the status of the migration batch.status of the migration batch

After the completion of migration, you can see the emails in the new Microsoft 365 account.


The manual method for migrating G Suite data to Office 365 is limited to email and can be error-prone. Missing entries in the migration file can cause errors, and the migration process may be interrupted if the migration endpoint loses contact. Import Google Contacts to Outlook may require a different method.

Furthermore, the manual method lacks filter options to select specific data from mailbox, archive mailbox, and public folders. To handle these folders separately and migrate them, it’s advisable to use professional software.
