This guide explains how to transfer to Infomaniak email addresses currently hosted by Google (with a custom domain). Refer to this other guide if you are looking for information on importing a simple Gmail address (…@gmail.com).

Preamble

• The operation does not affect either the data already present on the destination address or that of the source address.
• Any duplicates are managed: identical content will only be copied once.
• If needed, local partners referenced by Infomaniak can handle these procedures: launch a free call for tenders; they take care of everything, freeing you from technical details.

Google Prerequisites

1. Activate two-step authentication (2FA):
   • It is imperative to activate two-step authentication in Gsuite - if necessary, the organization's administrator must first allow users to activate it from admin.google.com.
   • In the settings of your Google account (https://myaccount.google.com/), go to the Security tab and activate Two-Step Verification:
     
   • Read the complete Google guide
      
2. Create an app password:
   • Once 2FA is activated, go back to Two-Step Verification and scroll to the bottom of the page to the app passwords:
     
      
   • Follow the complete Google guide:
     • Click on App Passwords.
     • Enter your Gmail account password if prompted.
     • Click on Select an app and then Mail.
     • Click on Select a device and select Other (Custom name).
     • Give a name to your password (e.g., Infomaniak), it is just descriptive.
     • Click on Generate.
     • Copy or note the password displayed on the screen (it does not contain spaces).

Infomaniak Prerequisites

• Have a Mail Service on your Infomaniak Manager.
• Have a quota of available free addresses or adjust it in advance if necessary.
• Ensure that the email is properly secured

Labels and data volume

The storage space displayed at Infomaniak may not match the one indicated in Gmail, particularly due to the different handling of labels/tags.

Indeed, these, present in Gmail, will be converted into folders on the Infomaniak servers (same principle as when retrieving messages with an IMAP email client/software like Thunderbird):

As a result, 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 can occupy 18 GB once transferred to the Infomaniak servers.

Adjust the application settings

As soon as you take the necessary steps for the domain name associated with your email to work with Infomaniak, modify the settings of the email clients/software you use so that they connect correctly to the Infomaniak servers: follow the configuration assistant.
