Is this user synchronized from on-prem? If so you'll need to update those attribute values on-prem. If it's a cloud user, I believe (95%~ sure..) that you can't edit those values unless the user is Exchange licensed.
Update user's Mail attribute in Azure AD.

Hi.
I changed an SPN of a user but the Mail attribute cannot be changed in the UI. It reverts the change, using AZ CLI it doesn't take effect nor with using Powershell cmdlet: Update-AzADUser. This is not an Exchange user so I would like to amend for consistency in the directory.
Can you please let me know of other ways to modify this attribute?
I will want to modify: Mail, MailNickname, and SMTP (Primary) ProxyAddress.
Thank you.
