Error: Method not found


You find the following error in the Event Viewer logs (in the Application branch) or in the CodeTwo Exchange Rules Pro and CodeTwo Exchange Rules family agent log files:

Method not found: 'Void Microsoft.Exchange.Data.Transport.Email.EmailMessage.Normalize()'.

and your emails are lacking signatures and disclaimers.


The problem occurs only on Exchange Server 2013 equipped with CU7 (build 15.00.1044.025) and is caused by a bug in the Exchange Server itself. To permanently solve the program you must install Cumulative Update 8 (CU8) or newer on your Exchange server. Older versions of the Exchange Server are not supported.
