In this article, we are going to discuss about the migration process of your email system from M365 to Carbonio CE. To perform this migration process, we are going to use Imapsync (a free, open source tool). You will find this article similar to the “The Ultimate Guide of Google Workspace to Carbonio CE Migration” as they are built on the same concept.
Imapsync can’t migrate Contacts, Calendars, Tasks nor Chat messages. Imapsync only migrates email data.
Working with imapsync
Imapsync works in a simple way. It pulls data from old server and then push it to the new server.
Important Fact:
Imapsync can’t migrate Contacts and Calendars.
You can get tons of articles on the internet about how to install imapsync server. To make it more convenient for you, I am sharing a sample imapsync installation steps.
You can check out this article where we have used containerized imapsync without getting into the hassle of installing it or using any third server.
- To proceed with this phase you need docker in you system. If your new system comes with a pre-installed docker then it’s fine or you can install it on you own. For example:
If your system does not have docker installed, then while executing next command you will get this error:
root@mail:/opt/zextras/backup/# docker pull gilleslamiral/imapsync
Command 'docker' not found, but can be installed with:
apt install docker.io
root@mail:/opt/zextras/backup/#Then, you can just install docker using onscreen help.
root@mail:/opt/zextras/backup/# apt install docker.io -y- Now install imapsync using the docker container.
root@mail:/opt/zextras/backup/# docker pull gilleslamiral/imapsync

Status: Downloaded newer image for gilleslamiral/imapsync:latest
docker.io/gilleslamiral/imapsync:latest
root@mail:/opt/zextras/backup/#Note:
Using docker image of imapsync is a smart and convenient way of using imapsync. Let’s take a look at some of it’s benefits:
1. You do not need a third server to install imapsync which reduces the dependency on third server and removes all other factors that can affect your migration process (i.e. interconnection between source server – imapsync server – destination server)
2. You do not want to install the imapsync server into either of your servers (Source or Destination) as it can jeopardize your server configuration.
3. When you are using the containerize version of imapsync, then you do not need to take any hassle to install and configure the imapsync server.
Note:
If you don’t have the credentials of a global administrator you have to create it on the source server. Now, do a test run before executing a massive sync process. Imapsync supports delegated auth login (--authuser1, --authuser2), so it is possible to migrate accounts even without knowing each individual users passwords (using a global administrator credentials).
Preparing Google M365 Account For The Migration
There are few things you need to do to prepare your account for the migration.
- Go to your Microsoft account’s Security option from the account settings.
- Select Additional security options. Find App passwords segment and select Create a new app password.
- Copy and save the newly generated app password your imapsync process.
Preparing Carbonio CE Server For The Migration
- Collect all email addresses from M365 and create them on Carbonio CE.
- Collect all email accounts password or reset them temporarily.
- Check status of all services.

zextras@mail:~$Migrate The Service From Old Server To New Server
We need to migrate the service from old server (M365) to new server (Carbonio CE) by changing the MX record. As soon the mail stops landing to the old server (M365), we will start the data migration process using imapsync.
Initiate Migration Process On Imapsync
Write down that imapsync script for each account and recheck them. For example:
docker run --rm gilleslamiral/imapsync imapsync --host1 Source_IMAP_Server --user1 imsilsa26112@outlook.com --password1 qmdfsdfypmlzmugg --host2 Destination_IMAP_Server --user2 sharif@example.com --password2 654321
So let’s execute our script on imapsync server:
docker run –rm gilleslamiral/imapsync imapsync –host1 outlook.office365.com –user1 imsilsa26112@outlook.com –password1 qmdfsdfypmlzmugg –host2 192.168.1.91 –user2 sharif@example.com –password2 654321
Important Notes:
Imapsync supports delegated auth login (--authuser1, --authuser2), so it is possible to migrate accounts even without knowing each individual users passwords (using a global administrator credentials). For example:
./imapsync --host1 imap_server/IP --user1 old_email_address --authuser1 --password1 auth_user1_password
--host2 imap_server/IP --user2 new_email_address --authuser2 --password2 auth_user2_passwordAs you can see already our Carbonio CE server is receiving messages from old M365 email account.
It continues syncing M365 account emails to Carbonio CE
But the imapsync process is not finished so, we have to wait to get all of our emails.
Meanwhile, if your imapsync server and Carbonio CE server can handle the load of multiple scripts you can run multiple scripts at the same time. But keep an eye on them so you know if anything goes wrong.
Our imapsync process completed. Let’s take a look at the cropped sample output.
