all attachments are now winmail.dat files
Very recently all attachments from any source have been converted to winmail.dat files in Thunderbird. It started a few days ago. On the gmail server they are still native format, so the problem is obviously on my Windows 10 PC. Thunderbird is my default email app. Something has changed that I can't figure out. Please help; thanks.

There is an add-on for decoding winmail.dat files:
https://addons.thunderbird.net/en-US/thunderbird/addon/lookout-fix-version/
https://support.mozilla.org/en-US/kb/installing-addon-thunderbird
and an article that explains how senders can avoid the problem:
http://kb.mozillazine.org/Winmail.dat_attachments#Disabling_TNEF_in_Outlook
While the Lookout attachment can decode the winmail.dat, file, the rest of this help text does not seem to apply.
- From the (work) Outlook, all options are set to HTML (i.e., not RTF), and I see the HTML plus attachments on the Android cell phone in Gmail.
- when I look at the gmail server directly (underlying Thunderbird), I see the attachments in native form.
Now I am wondering if somehow Windows Outlook / Office is intercepting the e-mail on between the g-mail server and Thunderbird on the PC and creating winfile.dat locally. Or, if the problem started with a Thunderbird update, that Thunderbird is assuming too much from Outlook metadata.
Anyway, this file response gave me a workaround, but not a satisfying solution.
It might depend on the Outlook version. There was a bug, which is supposed to have been fixed. But I suppose there could still be other bugs that make winmail.dat persist.
Latest Win 10 - Latest Thunderbird - Brand New Problem
With respect, I believe the critical points of this message are being missed.
I think the issue being reported is that just recently when receiving an email from an associate with an attached PDF file, (possibly other files) ONLY a winmail.dat file is shown as the attachment. Surprise, the winmail.dat file cannot be opened. The same email received via AquaMail on my phone shows the PDF attached.
When that message on the phone is forwarded from me back to ME, the PDF attachment magically reappears in Thunderbird!
My points are: - IF this is an issue solely with Outlook, we're all sunk. We cannot reach out to every contact and ask them to fix their software. - IF this is an issue solely with Outlook, what's up with AquaMail. It works. - CAN'T this be corrected here, in Thunderbird?

Having this as a built-in feature has been requested for (only) 20 years:
sfhowes,
Thank you for your response.
So, having this as a built-in feature is a good thing. Except, Thunderbird will no longer display attached files in a way that we can open them. Should I infer from this that we should all now go out and find an add-on that will solve this, and figure out how to install it? (OK, that was a bit sarcastic.)
With respect: IF AquaMail has figured this out, AND IF an add-on has figured it out, AND IF it has been anticipated for two decades, THEN, why hasn't there been an update of Thunderbird to resolve this?
I don't understand, rsw1941

Given the high number of users of the add-on, it seems it would be a good candidate to be built in, but the developers often place a low priority on incorporating features that are well-served by an add-on. Not saying I agree with that, but that's my experience.
