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...
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?
Not 100% sure, never had a 100% Cloud tenant to mess with. You'll find out after changing it quickly if you'll need it or not :). Because when you change it via on-prem you have to use the script I would suspect you have to change it using the script on cloud only as well.
- You can also change the domain for all the users in bulk using the bulk edit options in the users list in the Admin Portal...of course, this approach changes the domain, not the UPN...if you need to change also the UPN then you have to use PowerShell, but the process is quite straightforward
