AD User UPN changes

[Blue_Cookeh]

Hey,

 

I've not touched UPNs before, so I have a bit of a problem.

 

I'm deploying ADFS so we can introduce SSO with Office365, of course our internal domain doesn't match our school.xyz.sch.uk domain, though. Is adding a UPN suffix in AD and just changing all our staff user's UPN suffixes to this going to break anything in particular?

 

I'm just playing in VMs at the moment, but I don't want to come to do this at school and find it breaks everything

 

Thanks

We did it around half a year back now for our live@edu setup.

Broke nothing
