Thunderbird Support Forum

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

I have been struggling with slowness in Thunderbird in recent months (Windows 11, mid-range Lenovo laptop). There is often a distinct lag during even the smallest operations.

Examples are: selecting an email, closing a tab, typing, calendar events editing.

TB process in Windows usually uses 1000MB RAM. RAM is around 60-70% usage usually. I never have the same slowness issues with other applications.

I tried quite a bit: safe mode testing, removing extensions, compacting folders and more tips. I ended up removing Thunderbird and my profile entirely, and reinstalled the latest version with an empty profile. I just set up my Gmail and other email account. No extensions installed, yet still the same issue.

Could it be that something is still there from a previous install, if I removed my profile?

I've been using Thunderbird in Linux and Windows for years with moderate issues that I was able to resolve, but am now really puzzled. Please help.

I have imported a public key in my openpgp key-management/ In my settings of the end -to-end keys: preference of key technology: choose auto the key technology by the available keys. I have read openpgp standard supports inline en s/mime encryption but what is used by thunderbird when I choose openpgp as key encryption when i type/send an email (w/o attachment by myself). I ask it because my correspondent only decrypts inline encryption.

Dear sirs,

I believe that Thunderbird is one of the best email client programs available. This believe is the reason that i am trying to migrate to your email software. Sadly i have been experiencing a some dificulties on my main machine. I’ve tried for several times configurating the email on thunderbird, with sucess. The problem resides on every time that i close the program or restart my computer my email account vanishes from thunderbird. I am using an exchange2019 mail box. Could you please help me out with this situation.

Besr regards, Joaquim Nunes

I made no changes to anything, but a week ago, my thunderbird app on my computer stopped loading new messages and began to throw this alert when I try to save drafts or send messages: > Your draft message was not copied to your drafts folder (Drafts) due to network or file access errors. You can retry or save the draft locally. The email on my phone, through the mail app on iphone, still works perfectly. Both the thurnderbird and mail app are set up through IMAP.

I have both Gmail and Aol accounts on my installation, 115.9.0. My aol account is behaving funny. If I choose to display only unread emails, the screen goes blank and no messages show. I then click on sent message, click back on incoming and the messages reappear in the "all" messages display. The Gmail account is just fine, I can click between "All" and "Unread only" with no issues. Can't figure out what's going on.

Normally when you starting to write a new email, Thunderbird will set the 'from' address to the address of the account whose mailbox you're current browsing.

However, I have a saved search that entirely contains email from my secondary (work) account, but if I start a new email while browsing it, it picks my default (home) email address. This has caused me to accidentally send emails from the wrong address more than once!

Is there any way to change it so that it'll set the 'from' field of new emails to my work email when browsing that specific saved search?

I'm currently using Thunderbird version 115.9.0. For the last several months when I detach, delete or save an attachment, Thunderbird will duplicate the email. I then manually delete the duplicate.

This didn't happen the first several years I used Thunderbird. Is there some setting I missed? Any solution to prevent this from happening?

Thanks for any advice.

I'm encountering an issue with searching for messages that have been moved from the inbox to various folders in the local archive. After manually sorting messages by topic into designated folders, the search engine appears to correctly identify and list all relevant messages (as shown in picture 1). However, when I attempt to open a message from the search results, the subsequent window is blank (refer to picture 2). This suggests that while the messages are displayed in the search results, they cannot be accessed as their links lead to empty pages.

I have temporarily resolved this issue by rebuilding the global database using the steps provided in the following link: https://support.mozilla.org/en-US/kb/rebuilding-global-database. This fix, however, only applies to existing messages, and the indexing breaks again for new messages.

Similarly, toggling the search indexing on and off for specific folders only indexes the messages that were present during the indexing process. This problem persists across multiple installations of Thunderbird, indicating it is not isolated to a single instance of the software.

Is there any option that I should set for correct messages indexing?

Is there any setting I should adjust to ensure messages are indexed correctly?

Hi. When replying to an e-mail, Thunderbird has started to place to input cursor in the TO field instead of the message text field (in this case it should be before the answered text).

Any ideas? BR Johnny

Hello everyone!

I'm experiencing an issue with PDF attachments. Every on and then when I double-click on a PDF file attached to an email nothing happens. No action whatsoever. Thunderbird does not ask me if I want to open the file or save it. When I right-click on it and save the file on my computer the saved file size is 0 KB. I tried to access my emails using the browser and it works perfect. I can both open the file or save it on my computer and it saves with a proper size and then I can open it in Acrobat. Has anyone experienced a similar issue? I use Thunderbird SUPERNOVA 115.10.1 Windows 10 pro 10.0.19045

Thank you for any tips. Tadeusz

I have suffered a total hard drive crash. Fortunately, I had a complete disk image saved to iDrive. After many hours, I was able to find my profile in the appdata and watch yesterday as my 10000+emails (approximately 10 years of emails!) streamed into my new PC from my Comcast/Xfinity account. However, when I went to access my TB account this morning only a small percentage of the emails that downloaded yesterday were accessible. My TB email account is essentially the file drawer of my life. I want and need to be able to access all 10000+ on a daily basis. What did I do wrong? How can I fix this. Thank you so much!
