I want to be able to add a secondary email adresse @domaine.mail.onmicrosoft.com to all my new user account so that I can migrate them to my Office365 during the night.
I have a policy that creates new exchange account. I tried to add a new secondary email address to the account with the policy option "E-mail Alias Generation" but it doesnt work. I keed getting only the default Alias.
I tried with the policy option "Property Generation and Validation" and when I whant to change the value for the attribute proxyadress I always get some errors.
Do you have an easy way to add a secondary email?
