Hi - I have a client with a couple of domains sets up. We are in the process of moving them from 1 to another but if I change the default domain within the 365 set up, will this screw up those still on the old or just set the default for new accounts?
For example;
Domain 123.com (current default)
Domain 1-2-3.com
Existing users use a combination of the 2 domains. Going forward, 1-2-3.com will be the default. If I set the default to 1-2-3.com, will this effect people using 123.com?
The documentation suggests it will only effect new users but I'd like to be sure before hitting the button.
Thanks
