To-do list when changing the email domain

On Google or Microsoft, the email address also serves as the user's login ID.

The login ID is called UPN (User Primary Name), and the email address is the address displayed to your users when they send an email.

When changing domain names, there are several possible configurations.

1. Keep the User Primary Name and add an alias/new email address to the user account.
   

2. Update the User Primary Names with the new domain and add a simple alias with the old domain (to continue receiving emails sent to the old address).

Sigilium will help you with the migration.
To do so, send us a file with the following four columns to the address [email protected] :

• the old email address

• the new email address

• the old UPN

• the new UPN

As well as the planned migration date.
We look forward to helping you !
