Mailbox "%1" couldn't be removed because the DisableWindowsLiveId parameter on the Hosted management agent for Outlook Live Directory Sync (OLSync) is set to False. When the on-premises source account is removed, set the DisableWindowsLiveId parameter to True to disable Windows Live accounts. When the Windows Live account is disabled, it is removed and the owner of the Windows Live ID loses all Windows Live services.
