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.

Someone suggested BetterBird would be better for me than Thunderbird, but I'm not sure it was the right decision. They said I should be able to just open Thunderbird and it should work as they have the same base code, but it doesn't. Any ideas? I have 8 email accounts, so I'd hate to start from scratch.

Why do I get unwelcome changes with thunderbird? For some time now emails do automatically open when thy down load. Today when I click on an email to open the Bold print stays. So doesn't show as an already read. Like Thunderbird but may have to look else where if I have these annoying problems just pop up. Help................. John

I have a Dell Desktop with 64GB Memory, Windows 11, Intel Core i7-7700 @ 3.60 GHz, 1TB ssd, and two additional drives. On a new installation of Thunderbird 152.0, I get "System Integration" (Not Responding)" window. The only option is to exit. What can I check to correct this. I have uninstalled and deleted the install file multiple times with the same result. Thank you.

I can't add my Yahoo Mail account because of an authentication error.

The following message is displayed: "Authentication error Can't sign in to the server. Please check your username, password, and settings."

The authentication method "OAuth2" does not appear.

I can sign in and receive mail with the same ID and password in a web browser.

Thank you for your help.

new computer. Downloaded thunderbird. Added old email accounts. I have 4. I cannot send emails out with primary account. I can get secondary emails to send out. SMtp is comcast.

I NEVER want to mark all my email as read. How can I disable that functionality? I look forward to being able to also get rid of shortcuts that do not require ctrl, alt, or shift.

To get some information out of the way before reading: my verbose step-by-step is listed below, followed by a summary without the trouble shooting steps. I have read the information about managing profiles when running multiple release channels, but found it a little confusing. If I can improve the formatting here, please let me know and I will edit my post to be more clear.

I am leaving the troubleshooting steps in the event that I did something wrong here.

My questions are primarily: 1. is there a more straightforward way to do this? 2. are there any additional steps to follow after successfully getting both a Release channel installation and a Beta channel installation as far as profile management?

The problem, with step-by-step troubleshooting steps to solve I have Thunderbird Release installed on Linux Mint system-wide, following the instructions here: https://support.mozilla.org/en-US/kb/installing-thunderbird-linux#w_system-thunderbird-installation

Now I take note of the fact that beta must be installed in a different directory: "It is possible to have multiple channels of Thunderbird installed, and even run them simultaneously. Each must be installed in a different installation directory, which will force multiple Thunderbird data profiles to be used in order to protect and keep your data separated."

• ...so although I have an `/opt/thunderbird/` directory, I rename the downloaded extracted tarball `thunderbird-beta/` and move that directory to `/opt`

I move on to Step 4 from the article linked, creating a symlink.

• what I used to install Release: `sudo ln -s /opt/thunderbird/thunderbird /usr/local/bin/thunderbird`
• what I used today to install Beta: `sudo ln -s /opt/thunderbird-beta/thunderbird /usr/local/bin/thunderbird-beta`

Everything works from here as far as me being able to click on the `thunderbird-beta` executable in `/usr/local/bin` and get into the Beta application with a fresh program.

Here is the step I'm unsure of, and where I run into issues.

In Step 5 of the linked article, when I installed release: "Download a copy of the desktop file": `wget https://raw.githubusercontent.com/mozilla/sumo-kb/main/installing-thunderbird-linux/thunderbird.desktop -P /usr/local/share/applications`

...gives me a launcher in `/usr/local/share/applications`. I can edit this in a text editor to point to a different icon etc if need be, but when installing release this is obviously already configured.

So when I install beta, I don't want two of the same icons representing different Thunderbird channels, because my assumption is that will cause issues. So instead of downloading this file again, I copy the file I downloaded with `wget` when installing release, and instead of naming it `thunderbird.desktop` I name it `thunderbird-beta.desktop`

• I then edit this file in a text editor to point to the Beta icon in `/opt/thunderbird-beta/chrome/icons/default/default256.png`
• But the resulting file indicates "there was a problem launching the application" and when reopening the file in a text editor, I notice none of my changes have persisted and it's blank.

...I can confirm through a file manager that the icon at `/opt/thunderbird-beta/chrome/icons/default` is a visually different icon with "Beta" added to the bottom of the icon.

So this launcher in `/usr/local/share/applications` is the step I'm having trouble with.

Troubleshooting steps:

• I delete the previously edited `thunderbird-beta.desktop` file, and I rerun the `wget` command to download another copy of `thunderbird.desktop`, this time using the `-o` flag so that the resulting name is `thunderbird-beta.desktop` again. I again edit this with a text editor and point the icon field to `/opt/thunderbird-beta/chrome/icons/default/default256.png`

For some reason, this works: allows me to save my changes and the icon of `thunderbird-beta.desktop` successfully changes to the Beta icon. By default, with no other changes, clicking this successfully launches Thunderbird, but of course it launches my Release version, so I change the Exec parameter to point to the Beta executable in `/usr/local/bin`

And now I get my desired results: start menu entry, separate icon, and launching the Beta release.

So my primary questions again are: 1. I notice that simply running the Beta application once uses the same `.thunderbird` directory that Release uses, and creates its own profile folder, which seems ideal to me. Verifying that this is the expected and preferred behavior? 2. I'm confused about the support article for profile management when running multiple release channels. Do I want to re-add all of my accounts to Beta from inside the application, therefore having two copies of my mail and profiles on my computer?

I have Firebird Beta installed. I also have Outlook 2019 but after an update the address book is not visible. I have located the pst file(s) but don't know how to import the email address book from Outlook to Firebird Beta. Can you help?

We are facing issues with Thunderbird mail application.

Incoming emails are not being received in Thunderbird. Thunderbird is running very slowly and frequently becomes unresponsive. Sending and receiving emails is taking a long time. We have already restarted the application and system, but the issue still persists.

Kindly check the mail server settings and Thunderbird configuration from your end and advise on the necessary action to resolve this issue as soon as possible.

Your prompt support will be highly appreciated.

When I delete a message from the message list (not the first one), the next email selected is the first one in the list. This is a change in behavior - it used to the the one following the position of the deleted the email would be selected.
