Thanks a lot for your reply @wpo365 .

I have another question, what is the reason behind changes in the case sensitivity while users email addresses were not changed in the active directory?

Thanks, I posted this issue there now too.

the issue is that the user has admin access, administrator role should be revoked from this user, administrator role can access everything as per FAQ section
