I had this problem (.pdf attachments being corrupted on arrival) when I
switched
from POP to IMAP on entourage.
I went into my account settings (under Entourage message) and
"options" where it says "partially download messages over
X"
I changed X from its default of 100K to 2000KB (just to be safe.) I believe
that by default this button is checked when you set up your account, so if you
do nothing you won't be able to fully download large attachments. I believe
this is what entourage means when it says "file is corrupted or
unrecognized" - it's not really downloading it at all!
I then sent myself attachments including .docx and .pdf and they opened fine.
I went back to the attachments I hadn't been able to open earlier and they
both
opened fine (which was possible because IMAP leaves the copy on the server by
default.
So, at least in my case, despite the many messages about this problem on
various
internet forums saying check your cache, update your spyware, blah blah blah,
it's a simple setting on entourage. Hope that helps.
