Entra ID user home folder name

Question

Hello,

I am wondering if there is a way to change the naming convention used for users' home folders on Windows computers that have joined Entra ID.

While the home folders of on-premises Active Directory users are named after each user's UserName (the part in front of the at sign (@) of a user's UPN), the home folder names of Entra ID (Azure AD) users are essentially each user's first and last names concatenated.

For example, if a user called Alysson Cunningham (acunningham@contoso.com) exists on:

-> on-premises Active Directory, then her home folder name is C:\Users*acunningham*

-> Entra ID (Azure AD), then her home folder name is C:\Users*AlyssonCunningham*

We found out this behaviour only after we went from hybrid mode syncing to cloud only.

Thanks!
