Change primary Email Domain in Exchange Admin Center
Hello everyone, soon our company name will change and our domain will change from @myolddomain.com to @mynewdomain.com We do not have a hybrid environment, everything is in Azure and Microsoft 3...
Setting the domain as default doesn't affect existing users in any way. If you want to change their properties, such as UPN or primary SMTP address, you need to do so manually/via PowerShell. You can also use the bulk operations functionality in the UI, but that's only feasible up to a certain number of users.
As for the default .onmicrosoft.com domain, no, it will not change. And you shouldn't care about it. The only place that's visible is the SharePoint Online site collection address, but the ability to modify this is still not publicly available, afaik.

VasilMichev Thanks. Then I guess I will have to create a new subscription and migrate the Tenant
- If the SharePoint domain matters that much, that's the only option currently. Doesn't hurt to open a support case and ask Microsoft just in case.
