Ability to assign custom user home folder names
It seems it is not possible to change user home folder names in Windows 10 when it is managed by Azure Active Directory. Folder name gets created according to display name assigned in AAA.
For example, my display name is Kaan Türkeş and it creates C:\Users\KaanTürkeş
That is a big problem because many applications including Microsoft apps don't work properly when there is non English letter in folder name.
I can change my display name, but then in emails my name is not showing up but instead display name is showing. Even in external mails display name is showing up. I tested it with sending an email from a test account under my own domain to my personal Outlook mail.
