As of the newest TB version out July 31, 2023, I cannot send outgoing emails. Never had this problem with TB. After years of happily using TB and loving its wonderful functions and features, this inability to send outgoing emails is a mystery. Tried just about everything, but can find no fix. Tried to find a Mozilla-authorized earlier version to replace the newest version but could not find one on a Mozilla-authorized site to download.

Worked with 7 computer techs from the company from which I bought my new Win 11 computer this year--they couldn't find a fix. Worked with 5 techs from my Internet provider but not one of them could fix the outgoing email problem. Uninstalled, re-installed, repeated, checked all settings, stopped security software--nothing fixes the problem. My Spectrum webmail still brings in my incoming and sends out my outgoing emails but TB does not send the outgoing. I can only conclude the problem is the newest version of TB. Am I right? Is a fix on the way?

Who has run into this problem and how have you fixed it? Already spent 2 1/2 days working on this and not even the "computer experts" have a clue. Any TB heroes out there who can come to the rescue? Or should I wait a few weeks until this glitch in the newest version is fixed? Thanks in advance. I'm lost without my wonderful TB!

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I'm brand new to TB, and a novice at this, so thank you for your patience. I'm running the latest version of TB on a Windows PC. I have an Outlook email account that holds all of my Contacts. I know I can import those Contacts into TB - export from my iPhone, save file, then Import into TB. But how do I sync my Contacts between TB and my Outlook account? Thank you for your responses.

I downloaded Thunderbird 115 into Downloads/ directory Ubuntu 22.04 LTS and extracted the bz2 file. I did a cd to thunderbird and ran ./configure. Error the file was not found. What am I missing?

I'm transferring 10 email accounts for a client to a new service Dreamhost which recommends using Thunderbird. Backups include mbox, and zipped new/cur/tmp/maildir files for each account. I've installed the Addon importexport

but when importing in Thunderbird, 1) nothing loads into the account mailbox i'm importing to 2) a Local Folder appears 'Apple Mail Import" with nothing in it 3) and certainly no subfolders appear

I've tried with every conifuration that allows a zip There is content in those files, ex 400MB, 200MB, but nothing in thunderbird v. 102.10.1 Any thoughts?

Does Thunderbird no longer work with gmail or mailfence accounts? I have used Thunderbird for YEARS and now cannot get it to work with with GMAIL or MAILFENCE.......very frustrated!!!!! Thank you!

Hello. I think I am a little out of my league with this. I have set up Thunderbird and I believe that all of the information is correct, but Thunderbird just "Times out" Any help would greatly be appreciated. Thank you!

I would be very thankful if anyone would anoint me with the secret knowledge neccesary to re-add my generic SMTP email account after switching hosting providers. I'm stuck in what another poster has accurately described as "a maddening loop of impotence a maddening loop of impotence".

The problematic account opens and imports messages from the server, but I can't send any email. The pesky (and even auto-disappearing, see attachment) outgoing server password dialogue box appears and will not accept the password, no matter how many times it is pasted into the box.

Before bothering readers of this space I've read every post about the I could find about the issue here and on Reddit. Here's what I have tried:

1. Deleting the account from TB 2. Removing the saved passwords for all accounts on TB 3. Removing all SMTP servers from TB 4. Deleting the folder associated with the account from ~/Library/Thunderbird/Profiles⁩/[profileName].default-release⁩/ImapMail⁩ 5. Making sure none of my SMTP servers in Thunderbird share the same username and server settings as suggested in this thread.

I then re-add the problematic account in TB: 1. Using auto-detected settings (which match hosting providers settings) 2. Tried doing the same while in offline mode (as suggested here as suggested here) (result: the 'Done' button is greyed out and the settings revert to the previous hosting providers settings (question: where are these saved for retrieval in Offline-mode and can I delete them?))

I have four other accounts in TB with the same settings with the same hosting provider. They work and send emails. This to me pretty much rules out my port and server settings being wrong. Why can't I add my fifth account? Do I have to go through the hassle of re-installing Thunderbird and all my setup? Buy a new computer? I find this process to be opaque in the extreme and would much appreciate receiving the magic keys of knowledge. Your help is APPRECIATED. Thanks.

Also,

I'm trying to export my Thunderbird addressbook using the export function. I go to "address book"->"tools"->"export" and I get "Export Export accounts, messages, address books, and settings to a ZIP file. If your current profile is larger than 2GB, we suggest you back it up by yourself." Then it wants to export the whole thing as a Thunderbird Profile with no other choices showing. I can't seem to export the "address book" to the "csv" format which I used to be able to. Any ideas?

I received a message from Fire Fox that I should update. Now I have 2 Fire Fox icons and I need to know how to determine which one to delete. Then I need to know how to transfer my favorites and history to the one I keep. They both show favorites and history. I'm a rookie at this so if you can explain step by step it would help, thanks.

I have to use MSN now for my email server since your software no longer works!!! I can't send anything through your software now that you "upgraded" your TB software without my permission. Not sure why, but MSN is now saying that Outlook won't work with TB. So, good luck with that.

I have downloaded Firefox 113.0.1 for Windows x64 but the file seems to be corrupt. When I check the installation file with 7Zip Test Archive appeared a Warning Message due to a Checksum error. All others versions of Firefox downloaded can be checked correctly by 7Zip, but this installation file show an error message that I never have received. Is there a problem with the file? Thanks

Trying to transfer email accounts from old to new computer, but cannot access any messages on two accounts, both gmail, but a third has transferred correctly. One of those accounts contain additional folders accessible via the inbox. Followed instructions as shown on your transfer information page. Both Thunderbird instances are the same version. I can send and receive to the empty accounts and all others within Thunderbird. The account data is contained within the transferred Profiles/Mail folder but does not show within the program. All other data, including calendar events, have transferred successfully. Where have I gone wrong, or how can I remedy the situation?

What is the minimum version of Ubuntu to install Thunderbird 115 supernova? I'm on 20.04 on ZorinOS.

And by the way, when are you planning to make it available on APT?

Thanks, Tal Sabadia

Microsoft is discontinuing support for IMAP/POP on my website and now requires exchange. How do I add native support to thunderbird or is there a free add on. (I am aware of owl, but i'm not wild about paying even more money to send 1 or two emails per month).

I have used Xfinity for 15 years as my email service provider and used the same password for TB. Recently, TB stopped accepting the password. I changed it hoping that might help, but it did not help, I also reinstalled Thunderbird but it didn't help. Any ideas?
