Prepare your G Suite Account for Migration to Office 365


#1

Before you start migrating your Gmail account to Office 365, you will need to prepare your Gmail account. You need to turn on 2-step verification for Gmail and then create an app password that Office 365 will use with your Gmail address to make the connection.

Enable IMAP for Gmail and G Suite Accounts

Please make sure that you have enabled IMAP before you start the migration process. Failure to do so will result in migration-related issues.

To enable IMAP for Gmail or G Suite Accounts:

  1. Sign in to your Gmail/G Suite account using a supported browser.
  2. Click the gear icon located at the top-right of the screen.
  3. In the drop-down menu that appears, click Settings.
  4. Switch to the Forwarding and POP/IMAP tab.
  5. Scroll down to the IMAP access, and make sure that Enable IMAP is selected.
  6. Scroll to the bottom. Click Save Changes.

Enable your Gmail to be connected to Office 365

To use an app password with Gmail, you have to first turn on 2-step verification, and then obtain the app password. Once you have an app password you can use that in combination with your username to connect to Gmail.

To turn on 2-step verification

  2. Select Google apps > My Account.

  4. Under the Password & sign-in method, choose the arrow next to the 2-Step verification, and provide your password if asked.image

[!NOTE] If you have a Google Apps account and you can’t see this setting, your admin has to first turn it on. Please contact your system Administrator.

  1. On the Signing in with 2-step verification page, choose Start setup.
  2. Re-enter your password if asked, and in the Set up your phone step, enter or verify your cell phone. On the next step, enter the verification number sent to your cell phone and choose Verify.
  3. In the Trust this computer step, choose Next, and in the Turn on 2-step verification step, choose Confirm.

To create an app password

  1. Sign in to your Gmail account.
  2. Select Google apps > My Account.
  3. On the My Account page, choose Sign-in & security.
  4. Under the Password & sign-in method, choose the arrow next to the App passwords, and provide your password if asked.
  5. On the App passwords page, in the Select app drop-down, choose Other (custom name).image
  6. Type in a name (for example, “My Connection”) and select GENERATE. Find the app password under Your app password for your device. You can use this with your Gmail address in the app you are connecting to your Gmail account (or adding your Gmail account to.) This combination grants complete access to your Gmail account on the part of the app that is using it. After you have entered the app password, you do not have to remember it.image

[!IMPORTANT] The 16-character app password is displayed with spaces so that it is easier to read. When you enter it to the app you want to connect, ignore the spaces and enter it as a single unbroken string of 16 characters.

  1. Now your account is ready to be migrated to Office 365. This is the password that will be provided for migrating to Office 365.
