Event ID 4999 is logged and remote procedure call Client Access service crashes in an Exchange Server 2010 environment


The event log resembles the following:

Log Name: Application
Source: MSExchange Common
Date: Date 
Event ID: 4999
Task Category: General
Level: Error
Keywords: Classic
Watson report about to be sent for process id: Process ID, with parameters: E12, Build TypeVersion Number, M.E.RpcClientAccess.Service, M.Exchange.StoreProvider, M.M.PropValue.MarshalToNative, System.AccessViolationException, XXXXVersion Number.
ErrorReportingEnabled: False


This issue occurs because a Microsoft Outlook client tries to save a message that has many changes to recipients. Each attempt adds more and more AdrEntry array values and it causes an AccessViolationException exception that triggers the crash.


To resolve this issue, install Update Rollup 10 for Exchange Server 2010 Service Pack 3.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
