Never untick 'enabled' in MT4. This causes accounts to drop off from our reporting which cases lots of problems. The only accounts that should not have enabled ticked are those that haven't been verified or passed their quiz (If they are FM-AU clients), other than that, everyone must have enabled ticked. If you have been using this feature for closing down accounts or something like that, there are other ways to do this so the client can't access the account anymore such as changing the password, marking read-only as ticked, unticking send-reports etc.
