Attachments being logged in versaSRS as winmail.dat instead of the original attachment sent.

When an end user sends mail from an Exchange Windows or Outlook client, a file attachment called Winmail.dat may be automatically added to the end of the message if the recipient's client cannot receive messages in Rich Text Format (RTF). The Winmail.dat file contains Exchange Server RTF information for the message, and may appear to the recipient as a binary file. It is not useful to non-Exchange Server recipients.

The below linked article from Microsoft explains how to overcome this issue.
