The problem is not limited to exchange server. I experienced the problem with IMAP and gmail, and the google groups link above shows similar problems from others with IMAP and gmail. Of other reports I linked above, only one actually reported the problem while using Exchange. All these reports have in common:
1) Downloading mail with attachments
2) corrupt attachment
3) IMAP
4) Using TBIRD 1.5 and newer
Another observation:
- The problem happens with Exchange and gmail IMAP, perhaps other servers.
This bug is definitely related to IMAP, I haven't had any problems with tbird and POP3.
You will find a work around reported in two of the links above:
"I solved this, with a new value in about:config for Thunderbird
(Preferences->Advanced->General->Configuration Editor) or, if you
prefer, in pref.js:
