When attempting to run message tracking on an Exchange 2010 server you get an error similar to this: Cannot process argument transformation on parameter ‘Start’. Cannot convert value to type “System.DateTime”. Error: “String was not recognized as a valid DateTime.”
Can you spot the difference? Even if the server has a non US regional setting you have to specify the date in US format. e.g. 08/22/2013 instead of 22/08/2013.
