Exchange 2010: Missing Attachments

If someone sent you an email message with an attachment, but the attachment is missing when you receive the message, it may be because the type of attachment that was sent is not a permitted attachment type. You should verify that the attachment was a permitted file format. The following attachment types are blocked:

• *.bat
• *.com
• *.ps1

In general, the following files types are also blocked:

• Executable files (.exe, .dll, .ocs, .sys, .scr)
• Self-extracting executable files
• Java Archive format (JAR)
• Microsoft Cabinet Archives
• Java Bytecode format
