Thunderbird Support Forum

Dear all,

Microsoft banned all basic authentication method from Office365 because these method does not support multi factor authentication.

After that, I reconfigured the the configuration by used OAuth2 method on latest version of Thunderbird (78.5.1 (32-bit). The result as follows: + Can not receive new email from Offfice365 (Alert: As attached file No. 1)

+ However, I can send the email normally with OAuth2 via SMTP

Please help me fix this problem.

Thank you so much for your support.

I have been trying to figure out a way to change the font sizes in Thunderbird 78.4.3. None of the "help" works. Font changing extensions are out of date. Help threads point to menu items that aren't there. Can't even find the "config.editor". My eyes just can't handle the small fonts anymore.What can I do?

Captain Quack.

We are moving and I will not be able to access my computer for 2 weeks. I need to know how to set up "Out-of-office" reply. Any help will be appreciated.

I've used Thunderbird for years. After the most recent update in late July 2020 (78.0.1), Thunderbird no longer works. It will not download new mail. It does connect to the IMAP server but then gets to "checking mail server capabilities" and hangs with the spinning circle indefinitely.

I have not done anything to Thunderbird, I just let it install the update. I did not install updates to any other program on my PC. I'm running Windows 10 on a laptop that is about 4 months old. Thunderbird worked absolutely fine before the 78 update.

I am not experiencing any connection issues or problems with any other running programs.

I have tried the following fixes already: 1. Checking my account configuration and confirming it is correct with my email provider. I have the correct ports listed and correct server names. 2. Changing the timeout setting from 100 to 2000. 3. I am able to access my email on my provider's Web interface so this isn't a password issue. There is no CAPTCHA required either. 4. I checked my anti-virus/anti-malware program (Kapersky). Thunderbird and Mozilla are both listed in the "allowed apps" list. I tried removing them both and re-adding, as well as searching for other variations of Mozilla/Thunderbird to add. I also tried Kapersky's "refresh" function. 5. I tried restarting my computer. 6. I tried rebooting my wireless Internet connection. 7. I tried using Thunderbird's "start in safe mode with apps disabled" function. 8. I tried re-installing 78. 9. I tried clearing caches and cleaning with CC Cleaner.

Nothing has worked. Something in the 78.0.1 update has messed things up. Thank you for looking into this.

Hi,

I use the archiving feature of Thunderbird to move e-mail into yearly archives (Local Folders). I now have yearly archives going back a number of years. I appreciate the fact that they can be indexed by the search feature.

However they do take a fair amount of space on my laptop. I'd like to move some of the older years to a networked disk. I have several different e-mail accounts. My archives look like this:

  - Local Folders 
       - Comcast mail
             - 2011
                - Tree of sub-folders
             - 2012
                - Tree of sub-folders
             - etc.
        - Another mail ID
             - 2011
               - Tree of sub-folders
             - etc.

Can I select individual years within an e-mail identity and have only those on a networked disk? How would I do that?

What happens when I am away from my local network (and the networked disk with some of the Local Folders is not available)? Am I correct that those folders would simply not appear in my Thunderbird navigation pane? Or would it generate an error?

I generally set only the most recent years' archives to "Include messages in this folder in global search results". It's terrific to be able to find things from previous years, but I generally don't need to look back that many years. I also assume there's a performance penalty the larger the number of folders included.

Should I be sure that folders moved to the networked disk are set to NOT be included in the global indexing? Would having that set generate errors or strange behavior when I did a search while away from the networked disk? Or would the results in those folders show up (since they are in the index), but simply not be displayable?

Thanks for any help or guidance anyone can provide!

I have Thunderbird installed on 2 different machines. Keeping the messages in sync is no problem as they both use IMAP. However I would also like to keep the contacts in the address books in sync too.

Is there a way to do this?

Thanks

I would like to be able to automatically forward all email received from a specified sender but cannot figure out how to do this. I can only forward emails one at a time and even then it must be done manually.

I'm on Thunderbird 78.4.1 release. I can add an event in Thunderbird calendar, but it does not get added to Google calendar. I can add an event in Google calendar and it does get added to Thunderbird calendar. I can delete an event in Thunderbird calendar, that is also in Google calendar, and it does get deleted in Google calendar. I have 3 extensions: Provider for CalDav & CardDav, Provider for Google Calendar, & TbSync. I've tried enabling & disabling all combinations, but still cannot get Thunderbird calendar event to get added to Google calendar. Is there a post specifically for my release of Thunderbird that explains how to properly sync these calendars?

Hi,

I'm a long-time TB user, currently Portable Apps vsn. 78.3.1 (32 bit). My desktop PC (Win 10) suddenly failed to connect to my POP account. I don't think it's a server problem as I have changed no settings and my other devices (Android, iPad Air 2) still connect fine. The message I receive is: Thunderbird: Connection to server xxx was reset. I reinstalled TB Portable, keeping the same profile, etc., but I didn't really expect it to fix things and it didn't. I've tried safe mode but no joy, so I doesn't look like an addon problem.

Would anybody have any useful suggestions please, as I'm stumped :(

Thanks!

I want to import an old address book formatted as abook.mab by 5-10 year old TBs into current TB address book. The only article I can find on file doesn't appear to be addressed to current software, I can't decipher some of it, and what I do understand doesn't work. Any thoughts?

My mother changed her gmail passwords. She uses thunderbird for email. How do you change the passwords so that thunderbird will work and get her messages again.

There doesn't even seem to be an entry blank in the accounts pages to enter a password.

WHY HAVE YOU MADE THIS SO DIFFICULT?

I have tried to change font-size, font-color and font family as default for the messages that i am sending in the preferences but it does not work.

So i tried creating two files 1 ) ~/.thunderbird/r4f28oqg.default-default/chrome/userContent.css

/* Body */ body { font-size: 12pt !important; color: #006FC9 !important; font-family:Arial, sans-serif !important; }

2) ~/.thunderbird/r4f28oqg.default-default/chrome/userChrome.css

/* Body */ body { font-size: 12pt !important; color: #006FC9 !important; font-family:Arial, sans-serif !important; }

I am not sure how it works, i just want my my fonts to be with these default settings when i type and they should be received with the same size, color at the receiving end.

OS: Mac / 2020 Macbook Pro Thunderbird version 78.7.1 (64-bit) (most current) Provider for Google Calendar Add-on version 78.0.1 (most current)

Been having this issue for a while now - Calendar entries suddenly don't show up in the calendar tab and in the today pane.

I go into the calendar pane and click the eye shaped icon next to the google calendar I want to see, it all becomes visible again in both the calendar and today pane.

The next day it's usually gone again and I have to go in and make it visible. I don't shut down my computer or thunderbird. Calendar settings are set to "Show all calendars"

It's not a huge deal, but tedious to do every day and the whole point of having the today pane is that I'm not thinking about those things, I see them, I remember to do them. I don't always remember to refresh it and it's caused me to miss some things.

I have tried removing thunderbird and re-installing, that doesn't affect it. I have tried disconnecting/reconnecting the Google calendar, that doesn't affect it either.

Please help! Thanks
