Exim doesn't remove or alter attachments (or alter the bodies of messages
in general) unless someone configures it to do so. I think it's unlikely
that you would have done that by accident.

On the other hand, many organizations do deliberately configure their MTAs
to strip various types of executable attachments -- sometimes including
MS Office files -- in order to reduce the spread of viruses.
