Symptoms
The EdgeTransport process repeatedly crashes on a Microsoft Exchange Server 2013 server that has the Edge Server role installed.
To determine whether you are experiencing this issue, check the Application event log for an Event ID 4999 that resembles the following:

If you have any 4999 events that resemble this and the 4999 event includes the following text in the Description field (also highlighted in this 4999 event for clarity), then you are experiencing the symptoms described in this article:
edgetransport, M.E.MessagingPolicies.Rules, M.E.M.R.TransportRulesErrorHandler..cctor, System.TypeInitializationException
exSource=Microsoft.Exchange.MessagingPolicies.Rules|exMessage=Could not load file or assembly 'Microsoft.Filtering
Cause
This issue occurs if a rule is configured to delete messages that have specific text in the subject or in the body of a message. For example, this issue occurs when the rule contains the -SubjectOrBodyContains condition (also known as predicate). When any messages that don't match the rule are processed, the EdgeTransport process crashes.
Additionally, this issue occurs when another rule experiences an error during evaluation. In this case, the TransportRulesErrorHandler class is called and the EdgeTransport process crashes.
Resolution
To resolve this issue, install Cumulative Update 13 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.
