We are using hybrid Azure AD participation to log in to Windows PCs and manage MDM on Intune.
We are about to implement a support to change the domain of the email address of the user.
We are trying to change the domain of the user's email address, and I was wondering if the user's domain is changed in ADDC and the user information is updated via AzureADConnect.
I noticed that the user profile logged in on the Windows PC might be affected.
As for what I want to know, I would like to know which of the following two behaviors will occur.
When I change my email address, my user profile is rewritten with the new information and I can continue to log in.
When you change your email address, the user profile you had before the change is no longer available and you need to create a new profile with the new email address.
In the latter case, it is necessary to back up the local data associated with the user profile that is currently being used.
