Thunderbird Support Forum

I am sending an email to several people and others as a BCC. If one of those people who receives it as a BCC hits "reply all", will everybody see his reply? Or do BCC recipients even have the option to reply all?

Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

Gmail is going to require OAuth 2.0 sign-in SFAIK, that means I will no longer be able to access gmail with Thunderbird. Are there plans for Thunderbird to meet the OAuth 2.0 requirement?

I'm trying with utter lack of success to configure a Thunderbird install to link to a Gmail account via IMAP.

System Basics: Windows 10 Home, 64bit, fully patched. Antivirus by MalwareBytes 4.30 Premium, fully updated. No fancy firewall, just a regular router.

This account had been installed and working fine until a family member "helpfully" changed the Gmail password, but reauthentication fails. I enter the account details, including password, into the Thunderbird Accounts settings for the account; it pings Google and correctly retrieves all the IMAP settings, and when I click "Done" Thunderbird opens a browser window to Google's two-step authentication with the email address prepopulated. However, when I click the blue "Next" button on that authentication page, rather than advancing to a password screen, the browser simply deletes the email address from the text box and stays on the same screen (see attached image for what I'm talking about).

Things I've tried:

• Uninstall, reboot, reinstall Thunderbird.
• Turn off MalwareBytes protection.
• Uninstall, delete every registry key related to Thunderbird, reboot, reinstall Thunderbird.
• Clear cache on every browser on the system
• Change Windows default browser settings to either Chrome (see below) or IE/Edge
• Install new browser (Chrome wasn't yet on this PC), then change Thunderbird's file handler for https to Chrome (this is MUCH harder than it used to be as T-Bird v. 78.anything doesn't have the old "Preferences" menus)

Incidentally, changing browsers doesn't seem to make a difference in that pop-up browser window, so I suspect Thunderbird is using its own internal browser and not the system browser.

I have, and can send, the support info extract from T-bird to a support technician but am unsure of uploading it here. Nevertheless, I welcome suggestions ... this is driving me nuts!

Suddenly, Thunderbird 78.9.0 (64-bit) Win10 is very very slow

I don't want to reinstall and have to redo all my settings - anything I can do for this?

All else works OK on the PC, Thunderbird was OK before.

Any way to back up my settings so I don't have to do all that again?

Thank you

Since the update to ver 91, I often get "Unable to save your message as a draft. There was an error attaching (filename of photo). Please check that you have access to the file."

I have just had to install thunderbird on a new PC, and the email setup system is causing serious crash errors (red boxes with lots of text and Stack Overflow programming bugs (the actual thing not the website) ). I want to try installing an older version of Thunderbird, specifically 78.13.0

And I can't. The thunderbird website only gives me the ability to download the new version 91 or nothing at all.

I can find possibly older versions of thunderbird from 3rd party websites but they look a little.... off and I don't fully trust their content,

But, Why on why can't Thunderbird offer historic downloads of previous versions for those that need them or those that want to explore if they work on our specific systems.

How do I download version 78.13 from a reliable source?

Many people, including myself, use a received email to reply to sender / senders about issues unrelated to the thread. For this reason, I prefer to see all emails displayed individually without reference or linking to previous ones. How do I turn off threading? Thanks

TB 91.7.0 (64-bit I used to send/rcv gmail no problm, started having issues ~ Oct 2021 I then setup a 3rd party app password in gmail account for thunderbird. That allowed me to Send Gmails, but, not receive it kept asking for password. Then I read to use OAuth2 and saw that Google will no longer allow 3rd party app passwords, so i deleted it in google, and set both Imap.gmail.com and smpt.gmail.com to use OAuth2 (both set for SSL/TSL). I did this just for smpt first when the 3rd party app password was still enabled, i could recv but, when i went to send, it would ask for password, i enter it, then it would sent msg to my cell phone to Allow thunderbird, i would press Allow on my phone, and Thunderbird would come up with Sending message.. with the progress marked all way to end BUT, it will never complete sending.... I have to hit cancel it then shows Failed message unable to authenticate. After I deleted the 3rd party app password in gmail settings, now when i start thunderbird or try to receive emails, it goes through the same authorization process with my phone, but, then never downloads any new emails. I have spend HOURS on this.. extremely frustrated (I have been forced to us ms mail which i really don't like, i am too used to thunderbird (although I wished thunderbird had check boxes on emails to select via checkboxes for delete, or moving, etc)

Hi has anyone find a good way sync microsoft office online (outlook.com) calendar in thunderbird? I have been trying to get a working solution with exchangecalendar add-on, but apparently this add-on has been deprecated. https://github.com/ExchangeCalendar/exchangecalendar/releases/tag/v4.0.0

Hi,

I have several Gmail accounts. I have been using Thunderbird for many years. POP3 I keep everything on my Desktop. I just got this from Google and I'm at a loss. Anyone have any idea if or how it will affect Thunderbird's login?

Google On May 30, you may lose access to apps that are using less secure sign-in technology ??????@gmail.com To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account (Link to my account) using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0.

What do you need to do?

Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google.

I have been using Thunderbird for several years for my GMail accounts, and have always preferred to download my messages using the POP and SMTP protocols, rather than use the IMAP protocol which leaves them all on the web. Google now inform me that "To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google or other more secure technologies, like OAuth 2.0. What do you need to do? Email software, like Outlook 2016 or earlier, has less secure access to your Gmail. Switch to Office 365, Outlook 2019 or newer, or any other email software where you can sign in using Sign in with Google." These changes are due to take effect from May 30th. How can I prepare for them and still use the POP and SMTP protocols after that date? Is OAuth 2.0 appropriate?

Since font size is controlled in Firefox by CTL +/- why not the same for the main screen in Thunderbird? Eyesight requires larger characters. Simple solution best. Past my time to futz.

Google has announced that after May 30, 2022 third-party apps that log into google with account name and password (which I assume includes Thunderbird) will no longer be able to do so, as they will enable 2-step verification. I currently and for years have used Thunderbird to pick up my mail from 5 accounts, 3 of which are gmail accounts. Will I be able to continue using Thunderbird after May 30, 2022? I have been unsuccessful getting any helpful information from google itself. They don't have a list of "trusted" third party apps that will continue to work with them. Anything people know about this will be helpful to me and appreciated. Thanks.

I've been happily using Thunderbird for email for many years. Recently, the gmail OAuth2 requirement has made my POP3 accounts quit working. Currently on 38.5 for Windows 10.

Following various posts, I've tried to convert two specific email accounts to imap, and things are not going well.

My primary email is already imap and works fine. I've tried multiple times to convert the other two, and my current state is I've deleted those two accounts entirely (via Account Actions). When I try to install Existing Account, I eventually get to the point where the server config seems correct, but hitting "Done" results in the above message. I'd be surprised if imap.gmail.com can only support one email address. The emails are named differently, and use different passwords. Imap is enabled via browser based access to both accounts.

Incoming server imap.gmail.com:993 Outgoing smtp.gmail.com:465

Suddenly, I cannot sent Spectrum email from Thunderbird. Spectrum checked things on their end and said all is fine. I turned off Deep Guard in my Anti-virus software (briefly) and that didn't help. I get this message when trying to send email: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout002.msg.chrl.nc.charter.net cmsmtp 47.134.62.67 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

I can receive mail fine. I tried to look at my outgoing 'settings' in tools but only see the setting for incoming with the port @ 993. I CAN send Yahoo mail from Thunderbird fine (though I cannot SEE any outgoing port info in that mail either). Hoping someone can help.

TIA...

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

Dear community, my customer is unable to send invoice email from his management software. They get the error "There is no default mail client or the current mail client...."

Can you please help me? Thanks

Thunderbird 91 opens inbox pdf attachments in a new tab instead of in Adobe Acrobat Reader. Is there a way to revert back to the old behavior where these were opened in Adobe?
