I have properly configured IMAP account NONE of my folders are marked for off-line use. I do not use off-line working.
When I'm getting new e-mail items, it happens sometimes that I cant open attachments. Associated application (e.g. MS Word or Adobe Reader) reports that file is corrupted or cant be opened. If there are a number of attachments, I usually cant open the last one. However I'm able to download attachments through web-interface on my e-mail server, and files downloaded in this way can be opened without any problems. I realized that in such situations attachment files saved from Thunderbird are shorter than the original files downloaded through web-interface or by another e-mail client.
By pressing "Ctrl+U" combination I can see the e-mail message source and an attachment base64 encoded and it seems that it is not completely downloaded.
I experience the above problem since the earlier versions. The same
situation happens on different machines, running under Windows XP
Professional Edition SP2 and Windows 2003 Server Standard Edition SP1.
Note that I do NOT interrupt downloading of the message. Deleting IMAP
mail cache also as rebuilding index doesn't help. After the same e-mail
is downloaded I cant open attachment and I cant open it after saving.
Reproducible: Always
Steps to Reproduce:
1. Send an e-mail with attachment to yourself (I sent an e-mail with 80 Kb .pdf attached)
2. Close Thunderbird if opened
3. Delete IMAP mail cache for the appropriate profile and IMAP account (I deleted all .msf files and containing directory)
4. Open Thunderbird, select Inbox for appropriate IMAP account
5. After message headers are downloaded, select the header of the mail you just have sent. Do not click headers of any other messages before, select exactly the one you sent. Do not interrupt downloading message.
6. Try to open attachment, in my case Adobe Reader reported that file is corrupted
7. Save attachment using "Save As" feature and compare its filesize with original file attached. In case of my 80 Kb PDF it was about 1-2 Kb shorter.
Actual Results:
Message is downloaded, but trying to open attachment by clicking it, or by using "Open" or "Save As" causes error in associated application. Message source (Ctrl+U) looks truncated.
Expected Results:
Message should be downloaded fully. User should be able to open attachments.

If download of the attachment completed with no error(both externally and internally), it may be loss of CR/LF because attachment as text or quoted printable instead of Base64.
(Q1) Mail form what mailer on what OS?
(Q2) What mail header is written for the attachment?
> Message source (Ctrl+U) looks truncated.
It sounds same phenomenon as Bug 330829. This situation is being analyzed deeper in bug 384819.

Looks to be similar phenomenon to bug 384819. I could see some bugs when IMAP server is Exchange Server during bugzilla search with "summary contains IMAP & download".
MS's Exchange Server?

My outgoing SMPT server was MS Exchange, but I don't think that it is

I'm not sure IMAP server is MS Exchange, perharps not. I don't know how
to determine it. For testing I used my own account on the free e-mail
service http://www.mail.ru and its IMAP service is imap.mail.ru
In bug 384819 the source of problem was interruption of message
downloading, but I didn't it. Reindexing or clearing cache helped in
that bug, in my case it doesn't.
I think it is not DUP, but more likely extension.
Below is sample message source (Ctrl+U), if it may help someway:

Problem when IMAP of MS Exchange is Bug 92111, and it looks to be different issue from Bug 384819(interrupted download).
Get IMAP protocol log for step 1 through step 5 in your comment #0.
And see flow, and check attachment related data such as length.

I think following is helpful for first analysis.
SET NSPR_LOG_MODULES=imap:5
If log for your problem is obtained, attach the log(do NOT paste log) to this bug(text/plain, if size is accepted).

Yes, disabling fetching by chunks resolved the problem.
Situation is questionable, looks that problem is likely to Bug 92111,
except I can't determine exactly, but I more than 80% sure that
http://www.mail.ru is not MS Exchange based. There are millions of
accounts on this free e-mail web-service, it is very popular in .ru
zone, I suppose they use something for Unix platforms, some other
indirect factors tend to make me think so.
I will try to determine whether they are MS Exchange based to mark it as
Bug 92111 DUP or to leave it as another case.

This bug is better to be kept independently if www.mail.ru uses Unix platform(then never MS Exchange), because Bug 92111 refers to MS Exchange case only and is already sufficiently messy, but this bug is very clean. I think setting dependency is sufficient and is useful for other users who will experience same problem as yours.

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:
user_pref(mail.server.serverXX.fetch_by_chunks, false)
where XX is the server for imap gmail."

I'm running TB 3.0.5 on Mac OS/X Leopard. I have several IMAP accounts,
one of which is served by servers administered by GoDaddy. No Exchange
servers involved in this account.
Yesterday, my wife sent me a very important document as an attachment.
It was a single page PDF file. The PDF file size is just under a megabyte,
about 1.33 MB when base64 encoded.
Evidently TB truncated it when TB downloaded it from the IMAP server.
The final multi-part boundary at the end of the final part of the multi-part
message does not appear in the viewed message source. When I attempt to
open the attachment, with Acrobat reader, Acrobat tells me the document has
been damaged.
The MIME structure of this message is
Multi-part/mixed
Multi-part/alternative
text/plain
text/html
Application/pdf
The last of these parts is truncated.
I have tried and tried to get TB to re-download this message, but it
will not.
This IMAP account is configured in TB to NOT "keep messages for this account
on this computer". I don't want it to store messages for this account on this
computer's hard drive, at least not when TB is not running. Despite that, TB appears to keep the messages for all the IMAP folders for this account in a single file named
~/Library/Thunderbird/Profiles/XXXXXXXX.default/global-messages-db.sqlite
That file contains the truncated copy of this mail message.
I suspect that if I could get TB to forget that copy, it might download a complete copy. But it's not clear how to get TB to forget the copy of that
message, or of all messages that belong in that IMAP folder, from that db.
I tried "rebuild index" to no avail.
I wasted damn near a whole day trying to read that message. Finally I gave
up and had her call and read it to me. I was later able to read the pdf file
with an OLD copy of SeaMonkey on another computer.
I want to know:
- how to get TB to expunge that truncated copy of that message
- how to get TB to download an untruncated copy and print it
- how to get TB to STOP storing copies of the messages in the IMAP folders
for this account in global-messages-db.sqlite

Title:
Thunderbird corrupts attachments from IMAP exchange server
Status in Mozilla Thunderbird Mail and News:
Confirmed
Status in “thunderbird” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: thunderbird
For the last two weeks, all the attachments I download from our
exchange server via IMAP cannot be opened. After downloading or double
clicking, PDFs and DOCs are reported broken, whereas before they
opened correctly.
I've been accessing my single Thunderbird profile on Ubuntu's EXT3
file system both from Ubuntu and Windows XP for three months now. Both
have the same problem. Roughly a month a go, some addresses of our
exchange server changed, but I do not know if that was the only
change. Downloading the attachments with Outlook via the Exchange
Server connection or a IMAP connection still works.
After downloading, the corrupt attachments are 20% smaller than the
ones downloaded with Outlook.
