Discover how to use OVH Mail Migrator

The OMM (OVH Mail Migrator) tool lets you migrate the contents of your Exchange accounts (emails, contacts, calendars, tasks, etc.) without having to export to an Outlook Data File (.pst), which can be a long and difficult process.

First, go to: OVH Mail Migrator.

Click on New Migration to go to the following step.


Source Account

Choose your current source account and enter your server settings.

If your source account is hosted by OVH, you can choose: Hosted by OVH (Autodetect). You must enter the email address in question then click on Detect Settings.

You will then be asked to enter a password.

For example, to migrate from an MX Plan to Email Pro: Server type: Hosted by OVH Login: Your MX Plan email address Click on Detect Settings Password: Your email account password

Destination Account


Choose your new account type and enter your email address and password. The server settings are filled in automatically.

For example, to migrate from an MX Plan to Email Pro: Server type: Hosted by OVH Login: Your Email Pro address Click on Detect Settings Password: Your Email Pro password
