Since it is a hybrid setup you need to do the change from local AD and force dirsync to get the changes reflected in cloud.

Thats what i thought (but when i look in local AD it is firstname.surname@test.com sorry should have said :)

Is there a constraint in having similiar name, would i need to purge entire mailbox and start again

Just looking for the best painfree way to do it, thanks for your comment
