A quick delete of the following keys and a reboot all sorted: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tree\Microsoft\Windows\PLA ExchangeDiagnosticsDailyPerformanceLog and ExchangeDiagnosticsPerformanceLog References: http://exchangeitup.blogspot.co.uk/2016/01/exchange-2013-error-microsoft-exchange.html
