Hello,

we have a reproducible issue in Thunderbird when forwarding emails with attachments.

Environment: Windows 11 Professional Thunderbird version 152.0 (The issue also occurred in the previous Thunderbird version) POP3 account Mail provider Strato AVG Business Antivirus installed, but the issue also occurs after testing AVG related settings Issue occurs with different attachment types and sizes, for example PDF and DXF files

Steps to reproduce:

1. Open an email with an attachment. 2. Forward the email using Forward Inline. 3. Add recipient and some text. 4. Save the message as draft. 5. The first save works. 6. Save the same draft again, with or without changing the text.

Actual result: The second save fails with an error message similar to:

“Your message cannot be saved as a draft. There was an error attaching [filename]. Please check if you have sufficient access rights to the file.”

Expected result: The draft should save repeatedly without an attachment error.

Important observations: The problem occurs with all tested attachments, not only one specific file. The file size does not seem to be the cause. The issue also occurred with a small DXF attachment of about 355 KB. The issue also occurs in Thunderbird Troubleshoot Mode. The issue still occurred after creating a new Thunderbird POP3 profile and downloading the remaining emails again from the Strato POP3 mailbox. Changing the draft folder did not solve the issue. Removing temporary Drafts files and rebuilding the Drafts index did not solve the issue. The issue originally appeared to be related to AVG, but later tests showed that AVG is not the main cause. If the automatically inherited attachment is removed from the forwarded message and then manually dragged again from the original email into the draft, the draft can be saved without problems. Changing forwarding mode from Forward Inline to Forward as Attachment solves the issue.

Conclusion: This looks like a Thunderbird issue with automatically inherited attachments in inline forwarded messages. The first draft save works, but on the second save Thunderbird seems unable to reprocess or resolve the inherited attachment and shows a misleading access rights error.

We would appreciate any advice on how to further troubleshoot or resolve this issue. If this is a known bug, we would also be grateful for any information regarding a planned fix or available workaround. We are happy to provide additional information, screenshots or perform further tests if needed.

I have created a new gmail address for my wife. Would like to add this address to my existing Thunderbird Mail account so that her emails also come to my Thunderbird email account. Not sure how to add her address to do this.. Thanks

Hi there,

I currently have three email accounts set up in my Thunderbird client. I’d like to disable the automatic marking of messages as read—but only for one specific account (mainly for my colleagues’ convenience, as it’s a shared inbox).

In Settings > General, I see the option to turn off "Automatically mark messages as read", but this would apply to all my accounts, which isn’t what I want. I’ve checked the Account Settings for the relevant account and couldn’t find a per-account option. I also looked for an add-on that might help, but so far, no luck.

Has anyone found a workaround or solution for this? Any advice would be greatly appreciated !

Thanks in advance, Cheers.

I hope you all are well!

I´ve been having a problem with thunderbird for a while now and today took the time to do the troubleshoot and checked all the account settings. no firewall, no add ons Researching the problem i came across the incompability of different TLS standards. Apparently when thunderbird updated to 78.0 in 2020 a lot of people had the same problem and solved it by downgrading . Since this problem came on suddenly, possibly when thunderbird upgraded automatically, and it only applys to select emails (about half) I guess different TLS standards, some of which are no longer supported by thunderbird, are the reason for this. If i log in to my mailaccount I can see all the emails, same goes for my mobile devices. That´s how i know thunderbird doesn´t display all the messages. My question: Did anyone else encounter this problem? Did I analize this correctly or did I overlook something? I don´t want to change to another provider. I always liked thunderbird for being simple and clean. But downgrading won´t be a sustainable solution either I guess. Thanx for your help. Have a nice day.

I have tried severals methods to import a pst file from outlook to thunderbird but no success.

To be clear, I have a new computer which I don't use outlook with. Then, fomr my old computer I have reduce my pst file less than 2G. I have installed the importexporttools NG extension but i cannot import this pst. If i want to convert the file, i have to pay. I don't want because i need to do it once only.

Who can help ?

Returned from a 1-month trip and my Windows11 would load - repair didn't fix it, so I had to reload Windows.

Now I'm unable to right-click on a photo and send it via my Thunderbird email. When I right-click on 'Send to', there's no email option showing.

Thanks in advance,

Scott

I am trying to add an Proton mail account to Thunderbird using the Proton Mail Bridge (PMB). In the PMB guide it is recommended to uncheck Account Hub in the Setting>General. The problem is that the Account Hub still pops up when trying to add a new mail account - it simply refuses to go away regardless of several restarts of both the computer and the mail client!

I have created folders that I want specific emails to be put in when they arrive. But I don't know where to create these rules. Creating the folders is easy but how do I create a rule that tells Thunderbird which folder to put emails from specific people/businesses etc

All of a sudden, i can not log on to my email accounts. I get a "failed" message for all 3 accounts. I get this message. Login to server mail.westpeake.com with username redacted@westpeake.com failed. Brian West www.westpeake.com

I just got thunderbird and I'm so grateful to the ones who have immediately answered my questions. Now I'm trying to transfer my email of thunderbird from my pc to my cell phone. I keep trying to take picture of the QR code and it won't take it. I tried with my regular camera and it took it fine. Can you help me? Thank you for your time and knowledge.
