2 Simple Methods to Import Gmail into Office 365

• 1st Method: Manual Way by using IMAP Migration
• 2nd Method: Professional tool

You can also do manual IMAP migrations on your own, but contacts and calendar information won’t be moved. You can also use this method to move from Gmail to Exchange on already set up servers. If you want to move from G Suite to Office 365, you can start with the steps below:

1. Check the domains that you own

If you can log in to your account with your domain registrar, you can set up the DNS record for your domain. Owning the domain name is enough for Office 365. The first step in moving from G Suite to Office 365 is to check your domain name.

2. Adding more people to Office 365

Everyone who wants to use Office 365 must have a licence. Before moving emails from Gmail to Office 365, every user must have an Office 365 mailbox.

3. Make a list of all the email addresses using Microsoft Excel

When making migration files, you need to know the password for each Gmail account being moved. Knowing every password is almost impossible, so you can change them and give each Gmail mailbox a temporary password. You don’t have to move all your Gmail mailboxes at once; instead, you can create batches based on what you need to do. In one batch, about 50K mailboxes up to 10 MB can be moved, and each user will be given one row.

• Choose “Users” when logging into the G Suite admin user console.
• Pick each user’s name and write down the email address that goes with it.
• Sign in to the Microsoft Admin Center now. Go to the “Users” menu. Click “Active users” after that.
• Remember the username column and the Microsoft 365 admin centre window as well.
• Put Microsoft Excel to work.
• Type the office 365 address in cell A1, the user name of Gmail in cell B1, and the password in cell C1. Look at this picture:

A1: Email address needed for Office 365 domain
B1: Email address on G Suite
C1 = Password used temporarily during the move

In the format shown above, you can enter one mailbox per row. You can put other email addresses, usernames, and passwords in the cells below. Even though the email addresses are similar, the environment has changed (from G Suite/Google Apps to Office 365).

Once you’ve put in all the email addresses, as shown above, save the file in CSV format.

4. Creating places where people can move

Technically, email migrations happen at the migration endpoint, where two email systems that are part of the Migration talk to each other. So, to connect Office 365 to Gmail, you need to make a migration endpoint. Here’s how to set up one or more migration endpoints when moving from Google Apps to Office 365.

• Follow this path in the Exchange Admin Center:
• Recipients >> Migration >> More…
• Choose Migration endpoints next.
• Click “New +”.
• Choose the IMAP option, since G Suite is based on IMAP, and keep the default settings on the IMAP migration page. imap.gmail.com should be set as the server.
• Click the Next button and do what it says. Then, click “New” to make a new endpoint for Migration.

The next thing to do is set up groups of mailboxes. This lets you sort your mail based on how important it is. It can also help you test your Migration before you move a large number of files.

5. Transferring mailboxes in groups

As a standard, you can start migrations by making batches with a small number of emails to test. You can start multiple migration batches simultaneously and compare how long each takes. This will help you figure out how long the whole mailbox migration will take. Migrations depend on batch size, speed, internet bandwidth, and the number of connections to the source email system simultaneously.

• Choose Exchange in the Admins centre.
• Follow the steps: Recipients > Migration > New > IMAP migration > Migrate to Exchange Online > Next > Move configuration. Here, you can change the order of the batch’s name. Batch1 is an example of this. You can make another batch of the same thing and call it Batch 2.

By default, the batch name shown is the name of the Migration being done at that time. You can use the settings to exclude certain folders from that batch if you don’t want them to be moved.

• If you want to send some users a copy of the migration report, click Next, then select Browse on the Start the Batch page. After the batch has started on its own, choose “new.”
• As soon as you see “Syncing status,” the move has begun.

Once the batch runs, you can check the migrated mailboxes’ status. Checking the batch name on the Exchange admin centre dashboard is a simple way to ensure. Sign into Office 365. Type in your username and a temporary password. Do a mail flow test to see if emails are coming in and going out correctly.

6. Setting the MX record to point to Office 365

The DNS records need to show that your domain has been moved from Google to Office 365. When the MX record was pointed to G Suite, all your emails were sent to Gmail. MX record helps the emails that come in to go to one inbox. There are many ways to change an MX record for different DNS systems. Before you can stop syncing with Gmail, you must wait at least 72 hours because that’s how long it takes for other email systems to notice the change in the MX record.

You can stop the sync with Gmail after 72 hours.

7. Stopping the sync between Gmail and Office 365

This is the last step in moving from Gmail to Office 365. Once your MX record points to Office 365 for at least 72 hours, you can stop the synchronization between Office 365 and G Suite. Before you delete the migration batch and stop syncing, ensure all emails are sent to Office 365. In the Exchange Admin Center, you can delete the batch of migrations. You need to ensure that the migration batch isn’t shown on the dashboard. If it’s not there, it means that the Migration went well.

After the Migration, you can import your Google Contacts and Calendar into Office 365.

Manual Method: IMAP migration has some drawbacks:

1. Emails can only be move from the user’s mailbox. IMAP migration does not move Contacts, Calendar items, or tasks from Source (Gmail) to Office 365.
2. Emails and folder structures move as they are.
3. Users or admins must manually export their contacts and calendars from the source and then import them into Office 365.
4. You can only move up to 500,000 items from a user’s mailbox to Office 365 from the source. Every time, the emails move from newest to oldest.
5. The most significant email you can move is 35 MB in size.
