Thunderbird Support Forum

i have 2 desk top windows 10 comps and an ipad and i phone which all share the same email address. 1 comp works fine, the other desktop and ipad will send emails but not receive them, the iphone can send emails and sometimes receives them but not all the time. IMAP port 993 and ssl/tls with normal password. Disabling Avast anti virus did not fix it. any ideas?

I cannot send or receive messages on my Thunderbird a/c. I Believe I have to firstly update my email password from my supplier (Spark New Zealand) but to date I have been unable to do this. When I tried to do this on line Thunderbird indicated they did not recognize my email account at all. What should I do?

I don't seem to be able to self help very good anymore, can someone please take the time to teach me / guide me through the steps ?

1. 1 can I set up Thunderbird to receive my Gmail email, and if so, how do I proceed?
2. 2: How can I set up Thunderbird on my iPhone?

I appreciate your time!

Thunderbird 115.12.1 (64-bit) on Linux Debian 12, I have several accounts in a panel on the left. When the accounts are collapsed, they unexpectedly expand and make it difficult to know which account's email I'm reading on the right.

How do I control that behavior, please?

On powering up my PC this morning, opened Thunderbird and everything was gone - email settings to my various accounts, settings, calendar, addresses etc nothing is left at all

All I have is a basic screen : "To set up your existing email address" etc

I keep getting "can't connect" message and I have to enter my password for outgoing mail. Incoming comes through no problem. How can I get Thunderbird to remember my provider password for outgoing? They obviously already have it for incoming.

I can not get thunderbird to stop opening a web page on start up. Deselect the "when thunderbird launches......." but it is turned back on once I close and restart

It actually opens my browser and opens a thunderbird donation page.....

After the update to 115.12.2 (64-bit) installed, I made a couple of changes to tasks and TB went sideways and crashed, and continued to crash upon startup every time I restarted, even after a reboot. So, I copied a backup of my AppData\Roaming\Thunderbird directory onto the TB AppData\Roaming\Thunderbird dir. Now TB starts, but I have only Mail and I see no way to get Calendar/Tasks back. How do I do that?

Compact folders: caused a saved draft email to disappear. Closing and re-opening Thunderbird resolves this. Suggest the help document https://support.mozilla.org/en-US/kb/compacting-folders-potential-complications be updated to advise this solution (before the user raises an issue). How does this message get to someone who can action this?

Regularly the messages in some subfolders are doubled. I don't know why or how it was triggered. It is very annoying, because some subfolders contain a lot of messages. Since I don't know how to get rid of this double messages, except by deleting them by hand one at the time, it is a very time consuming matter. I tried repairing the folder, but that didn't work. I already have had a folder where all messages were doubled several times. So every message was there six, seven, or eight times! Is there somebody with an explanation and - preferably - a solution to prevent this?

I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

I am trying to setup an Outlook account on Thunderbird and I get an error: "Unable to log in at server. Probably wrong configuration, username or password." I have an existing Outlook account which I am able to use on the Outlook app on Windows, the Android app and the web version on outlook.live.com I wish to have an e-mail client on my Linux Mint machine from which I can access my Outlook e-mails. To do so, I went to the 'Account Setup' page on Thunderbird and used these to set up my account: Your Full Name: <My Name> Email address: <email-id>@outlook.com Password: <My Microsoft password which I use to sign in to Outlook> Under Manual configuration: INCOMING SERVER Protocol: IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: OAuth2 Username: <email-id>@outlook.com OUTGOING SERVER Hostname: smtp.office365.com Port: 587 Connection security: STARTTLS Authentication method: OAuth2 Username: <email-id>@outlook.com

I am sure that the password I am using is indeed the correct password. I still get an error as shown in the screenshot on the Account Setup tab. How do I resolve this issue? Thanks a lot!

It seems as the interface thinks the window containing Thunderbird is longer than it actually is. The bottom part of the interface is missing and there's no scroll bar. This is most apparent to me in the Address book, where part of the fields is invisible, as are the Cancel/Save buttons. When I start Thunderbird, that bottom part of the interface would appear for about a second and then disappear. Resizing the window doesn't help.

When I start Thunderbird in Troubleshooting mode, the interface works fine, but "Reset toolbars and controls" and "Disable all add-ons" doesn't fixt the issue.

It might have started when I connected a secondary monitor, positioned above the primary. I thought disconnecting that monitor fixed it, but I since reconnected it and the issue now won't go away except when in Troubleshoot Mode.

Hi All my emails from before February 2023 have disappeared. I live in Australia my server is Telstra who informed me that it isn’t their fault and that I should contact you. Many thanks Bee

Every time I open up Thunderbird a tab opens up containing a Thunderbird Privacy Notice. As I'm working then every so often a number tab opens with the same information. If I'm in Thunderbird for long I can have a dozen on more identical tabs. How do I stop this?

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

I was finally forced to upgrade from win7 (which worked) to win 10 (me no likey) because of a required program which would not even install on win7. After the upgrade, which obliterated my hard drive of several important things, I am reinstalling TB. I always used an NAS directory for Thunderbird, and have email records going back nearly twenty years. I installed TB 115 and have tried several ways to get it to recognize my profile directory on the NAS to no avail. I tried copying data into the default directory the 115 install is looking at. The about:profiles shows it is looking in the correct directory, it produces a parent.lock file in that directory when I run the program. It does not give me my email, or contacts. I do not use the calendar or to-do lists.

My system is an AMD K6-6400K with 16 GB and a 500 GB drive. Though programs are loaded on the drive ALL data is stored in an NAS. There is about 375 GB available on the C drive.

I have used the cmd line to pull up profile manager, added a profile, pointed it to the data that is on the NAS, a parent lock file is created there too but it shows me no mail.

I have edited the profiles.ini file manually to have the program look at the directories, both the NAS and a local directory which has had the old files entered. Neither worked.

I tried opening TB and creating a new profile and pre-loading the info there, nothing. I've been at this for days now. I have uninstalled and removed manually all TB folders and reinstalled older versions to give that a go but without effect. I am no Luddite (Many years ago I owned a system integration, assembly and install company doing networking for the military as a civilian contractor.) but someone has to explain this to me like I am a five year old. There is no reason having my email back should be this difficult!

PLEASE give me a hand?

My TB directory appears in C:\Users\owner\AppData\Roaming\Thunderbird My old data folder was on a network drive at M:\Users\owner\AppData\Roaming\Thunderbird\profiles\k5zbs5az.default When I manually enter the M: address in the profiles.ini file, it "corrects" it to C:\Users\owner\AppData\Roaming\Thunderbird\ even though the switch 'relative' is off.

[Profile1] Name=default IsRelative=1 Path=Profiles/zpfeu8eu.default Default=1

[Profile0] Name=default-beta IsRelative=0 Path=C:\Users\owner\AppData\Roaming\Thunderbird

[General] StartWithLastProfile=0 Version=2

[Install5D388C1349709B37] Default=C:\Users\owner\AppData\Roaming\Thunderbird Locked=1

Running the Mozilla application with a specific profile using command line arguments brings up the program but no mail. It creates a lock file in the correct directory, but no joy.

I get no pop up error messages.

I can not send emails to anyone. I have checked everything listed on the email help support list. I have cox.net and went to them to get answers with no results.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.
