Will a new user profile get created for the existing user on the client machine while logging in after changing the UPN ?

[@MSFTWebCast]

No. The old profile will be used.

What should the administrator create first NT Login or UPN? or it can be both? how about the exchange email.

[@MSFTWebCast]

It should be UPN.

unable to understand the explanation of why we need to use multiple UPN suffixes.
Could you please explain in detail.
Thanks

For example, If user want to use their email-id for sign-in and that can be different from their current UPN. (Your domain is mylab.local and in exchange for email you are using @mylab.com format).
Most of time we use this settings with exchange server and in some other environments due to corporate policies or on-premises line-of-business application dependencies.
