This guide explains how to transfer to Infomaniak email addresses currently hosted by Google (Workspace with a custom domain or @gmail address), using an IMAP import tool.

Introduction

• Consult this other guide if you are looking for an alternative to this IMAP process: it is indeed possible to perform a Google Takeout export and then an mBox import on our infrastructure.
• This operation does not affect either the data already present on the destination address or the data from the source address.
• The entire external mailbox will be imported.
• Once the import process has started, it is no longer possible to interrupt it.
• Any potential duplicates are handled: identical content will only be copied once.

Import your entire email history

Infomaniak Requirements

• You must have a Mail Service on your Infomaniak Manager.
• Have a number of available addresses or adjust it if necessary.
• Make sure that the email is properly secured
• Create one or more addresses on this Mail service.
  • If you have many (10+) email addresses to create, please refer to this other guide regarding bulk creation.
• The destination email address must be linked to the user (= the Infomaniak account) you are using.

Import Gmail email content to Infomaniak

1. Click here to access the import tool (online service https://import-email.infomaniak.com).
2. If necessary, log in to your Infomaniak account for the relevant organization; the import will be done to one of the email addresses associated with the Infomaniak Mail web interface (online service ksuite.infomaniak.com/mail) of the Infomaniak account you are using.
3. Click on the import via IMAP.
4. Click on one-time import.
5. Fill in the field on the left with your source email address (from which the content will be copied).
6. Click on the "Sign in with Google" button that appears:
   
   • Make sure you are signing in to the Google account that you want to use for email migration.
7. Confirm that you authorize the Infomaniak tool to connect to your account (automatic process).
8. Once you confirm the pop-up, choose the email address to which you want to import the emails; the drop-down menu lists the email addresses currently associated with your Infomaniak Web Mail interface (online service ksuite.infomaniak.com/mail) for the Infomaniak account you are logged into.
9. After selecting the desired destination address from the list, click the blue Import Emails button.
10. The copy process has started. You can wait and view the result on the page once the import is complete, or close the window (the import will continue in the background, and progress can be tracked - see below).
11. A confirmation email will be automatically sent to all email addresses involved in the operation once the import is complete, indicating the number of messages copied.
12. Tracking is available in the settings of the destination email address, and only on the web app Mail (online service ksuite.infomaniak.com/mail).
13. Tracking allows you to view the import history for the address in question.

Adjust application settings

Once you have taken the necessary steps to ensure that the domain name associated with your email account works with Infomaniak, modify the settings of the email software/clients you use so that they connect correctly to the Infomaniak servers: follow the configuration wizard.

Labels and data volume

The storage space displayed in Infomaniak may not match the space shown in Gmail, particularly due to the different way labels are managed. Indeed, these labels, which are present in Gmail, will be converted into folders on the Infomaniak servers (the same principle applies as when retrieve mail using an IMAP email client/software such as Thunderbird):

Therefore, an email tagged in multiple Gmail folders may be counted multiple times during migration, which explains why an account displaying, for example, 6 GB in Gmail may occupy 18 GB once transferred to Infomaniak servers.
