Move from Pop3 To office 365 but with stll active licensed Sharepoint users.

New Contributor


I have a customer with office 365 8 licences.

They are using sharepoint and onedrive, with this licence as <name> They are 8 users plus  2 of them have PowerBI in your account.

He want to enable emails in office 365.

Question is whats going on now? Can i use the existing user setup and transfom it to the new domain name? Or i have to delete licence from onmicrosft account and add it to the new created user?

I attached a SS from users.

What will affect the existing installation in the sharepoint?

p.s. Also i will inform that will registered 2 domain names.

Thank you in advance!

Hi Ste Pap,


Step frist validate a domainname.


The next show them selve. 



You can have multiple domains in the same O365 tenant, that's not a problem. Once you add the new domain, you can change their UPN, email address and any other attributes to use it, instead of the one. Don't forget to configure the required DNS records.
