When PureMessage is installed on an Exchange 2013 Client Access (CAS) Server, EML files are written to the root of the system drive, by default this is C:\.

A typical file has the below properties:

File name: {DB35E454-E864-40fa-A27F-81AD8EE319F4}.eml

File contents:

X-Sender: <>
X-Receiver: PureMessage.Trigger@95B5EF1C.A6B4.483e.B662.9BF25F4DB9E7
To: PureMessage
From: PureMessage
Subject: Trigger
PureMessage trigger message sent by MailSending.dll

Client Access Servers do not have the Exchange Replay directory which is required by PureMessage.

What To Do
