I run an old imac with ventura 13.7.4, mostly i use my email prog from my server, but i can't get links etc. When i switch to Thunderbird, much of the time thunderbird just sits there, saying it's connecting, but it's not. i will dump it soon and try something else, i think. Sometimes it works.

I think i am running TB 159.0. I haven't the faintest idea how to access the TB app menu, but this is what it says on my app menu.

I can't upgrade my OS, it's a miracle this thing works at all any more. Yay for old geeks!

I use HTML as my signature. It has been working just find, but lately when people reply to me, their messages were coming in blue text. So today I changed the: Settings > General > Plain Text Messages > Quoted text formatting from blue colour to black (I have no idea how that was set to blue in the first place). that is all I did. Image attached of the change I made.

In any case, after that, when I tried to send a new email my HTML signature no longer displays the correct font (Pristina) but shows only variable text. The HTML file is not corrupt, it still looks fine in the actual file I saved, but, Thunderbird is changing it somehow. Even when I look back at sent files, Thunderbird is showing me the variable text and not Pristina.

Any assistance would be much appreciated. With thanks, NM

Meeting notices are showing locally as being stored in my Google calendar, but actually are not.

I have four email addresses in Thunderbird, say one@domain.com, two@domain.com, three@domain.com, four@domain.com. I get Microsoft meeting calendar invites from time to time at each of these addresses. I accept them.

I want my calendar also on my Android, so have subscribed to my Google calendar, say at address calendar@gmail.com, through the builtin Thunderbird feature of a calendar on the network.

After accepting a Microsoft meeting invite, say at two@domain.com, it shows up correctly in my Thunderbird calendar as being stored in my Google calendar:

  Calendar: calendar@gmail.com

But actually it is not in that calendar when I check the calendar on the web. And so of course are not synced to my Android.

Is the problem that in the calendar properties in Thunderbird that I have my main email address "one@domain.com" selected from the "Email:" dropdown? Should I change that to "calendar@gmail.com"?

If so, does that mean I also need to add "calendar@gmail.com" as an email account to Thunderbird? I have not done so yet, because I don't need email from that account, I am just using it for the calendar feature.

Thanks.

When I create an event in the Thunderbird calendar and enter text in the “Details” field, the text appears the same color as the black background, making it unreadable, as shown in the attached image. However, red and blue text displays normally. It seems there is no option to specify font colors in the calendar. I would appreciate it if you could suggest a solution. Thank you in advance.

I have saved my emails in the local folders, which is in my second drive (D Drive), I added extra folders named them as per year and in those folders per month. It shows the size of each folder amount of data but, nothing is there. I notice this when my C drive got corrupted and I had to reinstall windows 10 again. I did not reformat the D: Drive because there was nothing wrong with the drive. It used to be so easy in the pass to save emails. What is happening?

Thank you for any assistants in the future.

Dear Thunderbird Development Team,

I am writing to share feedback and request an essential usability improvement regarding keyboard shortcuts in Thunderbird.

While drafting emails, I frequently trigger the Ctrl + Enter shortcut by accident. This causes unfinished emails to be sent out immediately, leading to awkward and unprofessional situations with recipients.

To resolve this issue, I attempted using add-ons such as tbkey-lite to remap or disable the shortcut, but the configuration proved ineffective. As a temporary workaround, I have enabled the "Send Later" / delayed sending feature so I can intercept accidental sends in the Outbox. However, this is only a band-aid solution and remains a constant source of anxiety while typing.

I kindly request that future versions of Thunderbird consider the following improvements:

   Built-in Shortcut Customization: An option in the settings menu to disable, rebind, or customize global/composer shortcuts (especially Ctrl + Enter).

   Confirmation Prompt Toggle: A built-in preference to prompt a confirmation dialog before sending (e.g., "Are you sure you want to send this message now?"), which would prevent accidental keystrokes from immediately dispatching drafts.

Thunderbird is a fantastic, privacy-respecting client that I rely on daily. Having better control over critical keyboard shortcuts would significantly improve the writing experience for many users who face the same frustration.

Thank you very much for your time, dedication, and continued hard work on this project.

Best regards,|

I've been using Thunderbird happily for many years, but a couple of days ago, it started making problems. It sometimes shows only my mail address, but no folders, so I cannot get to my mails. Sometimes it shows only the folder for incoming mails, but no "sent". Or "sent" ist empty. Sometimes everything works. (I have a second mailaddress in this thunderbird app, for which all folders are present, no problems there)

I cannot receive mail from my Outlook.com account in Thunderbird. This does not appear to be a Thunderbird configuration problem.

Thunderbird 159.0 on Windows. IMAP: outlook.office365.com, port 993, SSL/TLS, OAuth2, username = full address SMTP: smtp.office365.com, port 587, STARTTLS, OAuth2, username = full address

The Microsoft sign-in window completes successfully and an OAuth2 token is issued and stored. Using the same token: 1. SMTP AUTH XOAUTH2 succeeds: 235 2.7.0 Authentication successful 2. IMAP AUTHENTICATE XOAUTH2 fails: NO User is authenticated but not connected. 3. POP3 AUTH XOAUTH2 fails with an authentication/protocol error

I also reproduced the IMAP failure with a raw IMAP connection, outside Thunderbird. A brand-new Thunderbird profile still fails for this Outlook.com account; a Gmail account in the same profile works normally. Thunderbird is up to date.

Outlook on the web works. IMAP is enabled in Outlook.com settings (toggled off and back on). The same IMAP failure happens on two different networks.

I have already contacted official Outlook.com support. They said IMAP is outside their scope as long as Outlook.com works in the browser, and directed me to Feedback Hub.

Is there any Thunderbird-side workaround, or any known Outlook.com IMAP OAuth2 bind issue and recommended next step?

I apologize in advance if I have sent out anything suspicious below. I have a question regarding the Thunderbird-Gmail transfers.

I have read about the article ([[Thunderbird and Gmail|https://support.mozilla.org/en-US/kb/thunderbird-and-gmail]]) regarding data transfers to Thunderbird from Gmail. I was wondering if it's possible to transfer all Gmail data of that email address (i.e. examplename@gmail.com) to the different email address for Thunderbird (i.e. abcde@thunderbird.com), rather than using the same email address that I use for Google's Gmail?

If so, should I follow what's described in the above article link, or is there a different way?

Also, what should I do with the websites that I log in to, such as social media, healthcare, business-related login information, etc. between email addresses from Google's Gmail and Thunderbird? I really don't want to mess anything up on any of my important personal stuff.

After many years I have recently been receiving intermittent server refusals, as many as 12 to 15 per day, on mail.twc.com with Spectrum. After confirming incoming and outgoing server settings, Spectrum advises that the problem is with Thunderbird.

Updating to the most recent [159.0 (64-bit)] update zapped my email account (gmail) settings. No, I haven't tried troubleshoot yet or re-entering all my IMAP settings. :) (I will when I can shoehorn the time.) My installation (64-bit) on the appropriate Windows version has had no problems for years, & updates have worked consistently (through both ap & OS updates, until this specific update.

My question right now is, has anyone else run into problems with this issue? I know it's not that much to go on, but I'm in a hurry & need to see if anyone else has experienced it.

TIA for any/all info. :)

I have installed Thunderbird on my MacBook Air (Tahoe 26.4) and synced all my hotmail emails from an account which I wish to delete. Do I need to do anything before deleting the account i.e. will they stay in Thunderbird or is there a setting I need to change first?

Our time zone (Vancouver, Canada) did not revert to Pacific Standard Time. We remained on Pacific Daylight Time. I changed the time on the computer system. However, when I receive emails in Thunderbird, it shows a time of one hour behind (PST) and not the correct time (PDT).

(Webmail does show the correct time.)

How can I change Thunderbird email to the correct time?

A timeout in the connection to the server means that I can neither receive nor send emails, even though this had been working until today. I'm working on the latest windows version. How to solve this problem?

Hello, I'm currently having a problem with Thunderbird version 15.9. I can no longer sign in to my Google-Account after I set new passwords and entered them in Thunderbird. Several attempts were unsuccessful. I then deleted all entries related to my Google account. Adding the existing account again failed. I received two error messages. Error message 1: “Waiting for authorization during sign-in". Error message 2: “The inbox server is already in use.” An other E-Mail Account runs perfect. I urgently need help.

Hi everyone,

Why is it not possible in Mozilla Thunderbird to compose a new message within a standard tab in the main window?

Or is Thunderbird designed in such a way that the compose window always opens in a separate, standalone window? There is currently no option within the program's settings to change this behavior to use a tab instead.

Thanks!

I cannot find an article that tells how to change to a new email ISP/Email provider while keeping all of my local folders. I would think that this would be a very common need as users relocate to different areas for new job or whatever. It's personal with me, I will not use Gmail, Yahoo, or AOL as my primary email.

Part of my problem has to do with the help aricles that direct me to a format that does not exist on myTbird ap ( 159.0)( on my Macbook pro Tahoe 26.7.1. Another problem is that I am constanly being interrupted by sluggishness occurring in last 3 days, probably from memory demands ot Tbird which is insane, I do not have that many emails and have never seen an email program using memory like this. I need accurate guidance to fix this. Help would be so appreciated.
