Migrating centron email addresses to MS 365

If you assign a different domain name to a Mail Basic or Mail Business mailbox, it will no longer be accessible via the email address originally created …

Prerequisites​

First step: Assigning a different domain or subdomain​

  1. Assign a different domain or subdomain to all Mail Basic and Mail Business mailboxes that you have set up under the relevant domain. We recommend using a new subdomain in this context. This change allows you to link the domain to the Office user accounts you wish to use. You can then create a corresponding Microsoft 365 user account for each Mail Basic and Mail Business mailbox.

If you assign a different domain name to a Mail Basic or Mail Business mailbox, it will no longer be accessible via the email address originally created. You should therefore ensure that you create a corresponding Microsoft 365 user account for each mailbox.

Creating a subdomain​

  1. Log in to your centron account and click on the ‘Domains & SSL’ field.

  2. Next to the domain used for the Mail Basic and Mail Business mailboxes, click the cog icon under ‘Actions’. Then click ‘Manage subdomains’.

  3. Click on the ‘Create subdomain’ button.

  4. Enter any name in the ‘Subdomain name’ field and click ‘Save’.

Changing the domain of Mail Basic and Mail Business mailboxes to be migrated​

  4. Then click anywhere in the ‘Email address’ line.

  5. Click on the ‘Change domain’ link.

Creating Microsoft 365 user accounts​

  8. Assign the required role to the Microsoft 365 user account so that they can carry out the required tasks.
