Steps to reproduce:

When I click on forward any email that has a pdf attachment, when I click to open the attachment and then I go to send.

Actual results:

It gives the following error: "Failed to send message, there was an error attaching "attachment_name". Check if you have access to the file.

Expected results:

It should send the message without the error.

Just to confirm, this is on Windows 10?
What version is stated in help > about?
Why are you clicking "open attachment" before sending?

I can't reproduce this with 93 beta. It forwards fine, with the attachment

When I click on forward any email that has a pdf attachment, when I click to open the attachment and then I go to send.

If you're trying to send (forward) an email that has the file you want to send open, in this case PDF, it might fail because the file is locked by the application (PDF reader, Acrobat Pro, etc.) or operating system. Can you forward if you don't open the file?

I too cannot reproduce this when I opened a PDF from an email and then forwarded the email to myself with the PDF still open. It also worked ok with a DOCX open in Word.

Also, are you sure you didn't use the Detach feature by accident?

Good morning, I'm using Windows 10 Pro 64 bits 20H2, and I always close the pdf after opening it, just to confirm the file before sending it. I changed to open the pdf with thunderbird itself instead of using adobe acrobat reader. Notice if it worked. Thanks.

Even changing to open the attachment by thunderbird instead of adobe reader, the error happened again, I sent an email, and in the second it gave the error. I'm even on another computer, running the same version of windows and thunderbird. If they find it interesting, I can record a video demonstrating the error.

Can you try something?

1. Do CTRL-SHIFT-J to open an Error Console window
2. Prepare an email in the manner that will cause this error message to happen but don't send it yet
3. Go back to Error Console and click the trash can icon at top left to clear screen
4. Go back to your Compose Window and send the email that you know will fail and pop up the error message
5. Go back to Error Console and, if you see any errors (usually in red), copy and paste the errors here. It might hold some clues

It does not display anything in the error console. I switched to opening PDF with EDGE, and the same error occurs.

I installed sumatraPDF and I'm opening the attachments through it, so far everything is ok. I forwarded about 10 emails in a row and did not have the problem. I'll be testing and I communicate anything here.

I have to many the same errors on ~200 machines, it started when auto update from 78.14 -> 91.2.1 was done and many my users reported this issue. I have created filter rules, to forward mails when it arrives to the inbox (without opening the attachment in it). The error displays every time when filter is taking an action :/ Is there any possibility to revert back to TB 78.14 ?!? without breaking the profiles ? There is more problem - S/MIME signature is broken on TB 91.x - people with m$ outlook is reporting that the message has invalid signature (even on TB 91.3.1 - the file permission error and S/MIME signature error presist)...

Here I tried several things, including using windows 11 and the problem persisted. Solution was to downgrade to 78.14.

What about profile - when i install 78.14 over 91.x the profile manager refuse to enter to my mails becouse "a profile is from newer version of thunderbird" bla... bla... What ican do, to saftly downgrade users profile 91.x -> 78.14 ?

Try this: Windows key+R, type thunderbird.exe -p --allow-downgrade

I have the same problem on different machine under Windows 10 and Thunderbird 91.3.1. It concerning only pdf attachment files. Same error message, it is not always reproductible, sometines the message is send, sometimes there is the error message above.

It is clearly not a solution with a thousand of computer in 91.1.3, if the downgrading made by script failed, i am fired ;-)

This problem occurs when I forward a message with a PDF file attached.
I can reproduce it with these steps:

1. create a forwarding rule in the filter like: Mail is from xxx then forward to yyy
2. when I receive a mail from xxx, Thunderbird tries to forward the mail to yyy
3. the error message appears on the screen

I hope this will help

Thanks for the info. And this is on 91.3.1?

Yes, and also in version 91.3.2 (64-bit). I tried it with both versions.

url=file:///B:/USER_Q~1/nsmail-24.pdf

I'm just a user here but this part is intriguing. Any idea why it's pointing to B:/? Is TB not installed to your C:\ drive? If not, could it be TB is throwing a fit due to non-standard location or something?

B:\USER_Q~1 is the temporary folder (the %temp% variable on the system) TB is installed on drive c:.

(In reply to spam from comment #21)

B:\USER_Q~1 is the temporary folder (the %temp% variable on the system) TB is installed on drive c:.

Hmm..the rabbit hole just got a bit deeper. What kind of disk is B: ?

I don't know if this is the right direction to look for.

This is the trace from the process monitor. You can see the file was created, deleted and TB tried to reopen the deleted file. Can you confirme this to me, or am i making a wrong assumption

So again, what kind of disk is B:? Mapped? USB? Physical? NAS? Drive letter B: is usually reserved for legacy floppy drives. Did this ever work for you before using 91.x?

You are right. The drive is normally used for floppy, but it is a standard physical SSD with NTFS file system.
And worked fine for all TB versions before 91.x.x

You are right. The drive is normally used for floppy, but it is a standard physical SSD with NTFS file system.
And worked fine for all TB versions before 91.x.x

How about a little experiment? For kicks and grins, can you try to repro using TB Portable 78.14.0 (https://portableapps.com/apps/internet/thunderbird_portable)? It's won't modify or mess with your installed TB 91.3.2 and associated account(s) as it's self-contained.

1. Download TB 78.14.0 Portable to desktop
2. Shut down your installed 91.3.2 so it's not running (use Task Manager to make sure, else it'll complain about TB already running)
3. Double-click the PAF installer for 78.14.0 that's on your desktop (it will extract itself to a self-contained ThunderbirdPortable folder on the Desktop)
4. Launch TB 78.14.0 Portable and set it up to use the email account that's having the forwarding attachment issue
5. Find one of those emails with a PDF attachment that you want to forward (but is currently failing when using 91.x) and see how 78.14.0 Portable handles it

Does it send with 78.14.0 Portable?

I have tried the portable version.

It works without any problems. Here is the filetrace if you need it:

Any progress on this bug ? Making manual downgrade to 78.14 and lock auto upgrade on ~200 machines is not cool...

Sounds like bug 1741805, which will be in beta 95.0b5 (releasing in the next 12 hours). Suggest you TEST it in a new Thunderbird profile (unless you are already using beta). Available at https://archive.mozilla.org/pub/thunderbird/releases/95.0b5/

I notice https://searchfox.org/comm-central/rev/79d2504137747f6d0e61ddd815adcfc496644ddb/mailnews/compose/src/nsMsgCompose.cpp#3261 will always fail, at least for the forward message to filter. It wouldn't seem to cause anything other than console warning about failure.
