Impacts of changing default domain in Office 365 tenancy?
A client of mine has decided to change their company name and default email domain, an I have a few questions about what this impacts. Can I simply add the new domain to my current Office365 te...
My two cents here:
1. You can add as many domains as you want/need in Office 365, but just remember that adding a new domain does not imply the default onmicrosoft domain is going to change, it remains the same...so the name change cannot be reflected in Office 365
2. You can add the new domain and easily add to every user in the tenant so the can log in using the new domain.
3. Yes
4. No, the OneDrive folder will stay with the original name.
5. No.

Adding my input here.
1. This one is in conjunction to Dean's response, the actual domain URL used for onedrive/sharepoint cannot be changed currently. You can add as many e-mail domains as you wish, you can even change your primary domain via exchange policy so it auto updates the e-mail where it comes from. Making the domain primary may even do that as well, I do it via Exchange thou because Hybrid, so depends on if your hybrid or not how that goes.
2. you can add new domain and make it primary. However you will have to run a script to change everyone's UPN logins. Something like Set-MsolUserPrincipalName -NewUserPrincipalName user@newdomain.org -UserPrincipalName user@olddomain.org
3. Yes
4. OneDrive will not change existing folder, however, new setups going forward will use the new Organization name if you change it. And if you remove and readd onedrive the default will update to OneDrive - Orgname
5. Nope, and If your talking about the URL to the notebook, see number 1. Maybe someday but right now not possible to change that URL.Do I have to use a script to change everyone's UPN login, even if I'm using 100% cloud hosted Office 365 (i.e. non-hybrid)? Or if when I make the new domain the default, will that automatically trigger all Office 365 users' UPN logins to use the new domain credentials?
- Changing the default will only change the UPN for new users created in future - you will need to change the UPN for your existing users, as others have mentioned.
