A few times a week I get email from some sorry Outlook/Exchange user which contains a dreaded winmail.dat file. Being a Thunderbird user, this presents a bit of a problem--one that has been well documented in Dealing with the winmail.dat file and unreadable attachments and How to Prevent the Winmail.dat File from Being Sent to Internet Users.
The are various "free" winmail.dat readers around, but this is 2008 not 1998. I shouldn't have to install the email equivalent of a "helper application" to read a fucking word doc that crappy email software couldn't encode in a sane format.
So anyway, I got one today and actually needed to read it. And I hadn't installed one of those stupid winmail.dat decoders since I had my laptop replaced. Faced with the prospect of actually installing software I wondered what'd happen if I forwarded a copy of the message to my Gmail account.
Well, wouldn't ya know it? The damned thing came through just fine. I was able to extract the attachment and open it faster than you can google "free winmail.dat decoder."
Kick Ass.
Just for kicks, I sent it to my dormant Yahoo! Mail account too... and it was also able to extract the Word document from the winmail.dat file.
Now why on earth hasn't this functionality been built into Thunderbird? Or Windows for that matter?
It's days like this that I might confuse my laptop for a stone tablet... just for a moment or two.

Hey Jeremy -- I'm with you on that. I don't quite know the story about winmail.dat handling and why it's not part of the standard Thunderbird build, but that's the kind of stuff that I'm hoping to tackle with the next releases. That, and calendaring, and switching to using SQLite for indexing contacts and emails, and, and, and...!
In this case, I suspect the history is that Mozilla tries to carefully balance the usability benefit of adding the feature on one hand, with the "internet health" concern of enshrining support for a non-standards based format on the other. My call on this issue would be to follow the old robustness principle ("be conservative in what you do, be liberal in what you accept from others"), and hence add the feature to Thunderbird core.
As a funny coincidence, today I considered blogging asking why my iPhone IMAP reader can read Excel attachments but can't handle ".eml" attachments, which AFAICT are just RFC2822 of some sort.
The first line says it all: some "sorry" outlook user. yeah, like everyone on the planet, you mean? Sounds to me like the thunderbird user is the one who is sorry.. Outlook, IE and the rest always worked like a charm for me.
And going back to a statement I made a while back - I haven't seen a virus on any client system I support in over a year now..

Chris: no, not all Outlook users are sorry. But there are enough of them out there that I seem to bump into them on a routine basis.
Judging by bug 77811, there's an extension at http://lookout.mozdev.org/ which reads them, that the author is willing to tri-license and contribute, once David hires someone with the time to work with the extension author to turn it into acceptable core code :)
(Not sure whether it's already tri-licensed, since Mozdev's CVS viewer seems to just want to tell me that my "IP Has Been Blocked From Mozdev ..." today.)
How did you do it? I had only the option to download the file in gmail. If I download it, it is still a .dat unreadable file...
How about this interesting problem, which probably means that their is a problem with the Exchange setup at work.
Yesterday I replied to all to a message from an outside person and I added 3 people inside the company to the reply. Two of the people inside received a winmail.dat file instead of the message. To me that is really strange because the message didn't even leave exchange. We are all using OL2007 and the message was in HTML. We tried resending in RTF and TXT and they still couldn't get the message.
Hi,
I'm currently in the proces of moving all my Outlook mail (from a local .pst file) to my gmail IMAP account.
Many messages now have a winmail.dat attachment and when i click on it in Gmail, Firefox asks me what to do with it?
Maybe Internet Explorer has a built-in addon to open the winmail.dat?
