Migrating from one email platform to

another application is now very common. Some users are switching from paid

email clients to free applications, such as Outlook to Thunderbird and vice

versa. Among them, the queries migrated from Google to Office 365 attracted

half of the business.

Many organizations are moving their full

business collaboration applications from Google to O365 Online. Therefore,

whenever an email client change occurs, a technology is required that can

export the old data to a new application. Therefore, in this article, we will

show you a complete guide that can move Google data (G Suite / Google

application) to MS Office 365 inbox.

Technology to import  data from Google to Office 365

The IMAP protocol provides a free method to

migrate from GSuite Gmail to Office 365, but this has limitations because it is

not easy to support calendars or address books. For small groups of users, this

may be acceptable, but as you expand to larger projects, this constraint

becomes a problem. Office 365 has Google built-in migration options using the

IMAP protocol.

The migration speed may be slow, it is

recommended that you perform a test migration to provide an estimate.

You can use the third party tool to import

Google into Office365. Choosing the right tool is an important decision and

there are some differences to consider. For example, some tools provide a

Google Docs license to OneDrive.

The complete migration method using IMAP

will be presented below.

Import Google Apps to Office 365 step by step

There are two possible ways for IMAP

migration, namely Exchange Administration Center (EAC) and PowerShell.

PowerShell commands are very complicated and you need to be careful when using

them. Therefore, we choose the EAC method to import Gmail emails into O365

webmail. Follow the instructions below to complete the activity.

Step 1: List all mailboxes

The first step is to list the mailboxes to

import into the G Suite domain. To do this, follow these steps.

Note: The size of the list must be 10MB.

  • Log in to the Admin Console of Google G Suite.

  • Click on Users to view the user list.

  • The window will display the id of all users. Note the email address for later use.

  • After noting the user’s email

    address, log into the O365 Management Center.

  • Click on User >> Active


  • Select the details on the

    “Username” column.

  • Next, start the Excel

    application and create a table as shown in the image. You need to create three

    columns, which are email address, username and password. In the “Email

    address” column, write all the user IDs associated with O365. Then, type

    the user’s login name and password in the “Username” and

    “Password” columns respectively.

  • After completing the Excel

    worksheet, save it in CSV format.

Step 2: Connect your Gmail account to O365

It is mandatory to establish a connection

between O365 and the Google account to transfer emails. To establish a network,

you need to perform the following instructions.

  • Go to the Exchange Management


  • Click Recipients >>


  • You need to select the

    migration endpoint by clicking More Options.

  • Next, move the cursor to the

    “New” icon. It is used to generate new migration endpoints.

  • Next, you need to select IMAP

    from the next page.

  • In the “Configure IMAP

    Migration” page, input ‘’ in the “IMAP server”

    settings option.

  • Tip: Make sure the rest of the

    default settings remain the same.

  • Click the “Next”

    button and establish a connection between Gmail and the MS O365 account.

  • After the two accounts have

    been successfully linked, the “Enter General Information” dialog box

    will appear.

  • Just type a suitable name for

    the migration endpoint, then keep the next two boxes in a row. Then click the

    “New” button.

Step 3: You need to run the migration batch processing

This step is very useful when you need to

move multiple Google mailboxes to Office 365 at the same time. Read the

following steps:

  • Open the Exchange Management

    Center with the help of a browser.

  • After opening, select

    “Exchange” from the left pane.

  • Next, select the recipient and

    click on the migration option.

  • Click the New(+) button and

    choose “Migrate to Exchange Online” from the drop-down menu.

  • Select IMAP Migration >>


  • On the next page, click the

    “Browse” button and upload the migration file.

  • Next, O365 will check the file

    based on several factors, for example, the file must be of type CSV and the

    number of rows must be equal to or less than 50,000 or even more. If the file

    does not follow any parameters, an error message will be generated. Otherwise,

    all Gmail mailboxes will be displayed on the screen.

  • Click the Next button.

  • In the “Set Migration

    Endpoint” section, you need to select the migration endpoint you created


  • Select the default value from

    the IMAP migration configuration page and click Next.

  • This is the most interesting

    part when you need to provide a relevant name for the migration batch. If you

    want to remove multiple folders from the export task, you just need to type the

    folder name in the “Exclude folder” box. Then click Next.

  • On the “Start Batch”

    page, execute each instruction in turn.

  • Select the Browse button to

    share the exported report with sub-users. Alternatively, the user can go to the

    “Properties” option and view the complete file.

  • You need to select

    “Automatically start batch processing” and then click the

    “New” button to start the Google import process into Office 365.
