Cause

The issue is caused by a logic error that occurs in the TextConverter class when TextConverter performs a buffer copy operation.

Resolution

To fix this issue, install Cumulative Update 14 for Exchange Server 2013 or a later cumulative update for Exchange Server 2013.

Workaround

To work around this problem, identify the mailbox that caused the service to stop by using the RCA logs. Then, we recommend that you have the mailbox user change their Outlook setting from online mode to cached mode. 

Also, make sure that the user does not copy or move specific email messages to a .pst or local folder, either directly or by using an Outlook rule. To determine which message that is causing the problem, copy or move every message to the .pst file one at a time. The message that you cannot move is the one that is causing the problem. This problem causes a loss of connectivity loss or causes the RPC Client Access service to crash.

Status

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