You have an environment that has Update Rollup 4 for Microsoft Exchange Server 2010 Service Pack 2 (SP2) or a later update rollup that is earlier than Update Rollup 6 installed.
You send an email message that contains an attached Open Office XML document (for example, a .pptx or .docx document) that is missing a file name extension.
In this scenario, the Microsoft Full-Text Engine Filter Daemon (Msftefd.exe) process crashes. Additionally, the following events are logged on the Mailbox server:
