Thunderbird Support Forum

This is a recent issue. If I send an email with no images and no attachments, it copies the email into my "sent" folder with no problem.

If I send an email with even a small attachment...it sends the email, but "times out" copying the message to the sent folder.

I've checked the account/server settings, they are exactly as recommended. I've changed the sent files to "other"...no difference. I deleted and reinstalled Thunderbird...no change.

Ideas?

I have to manage a number of joint email addresses which are outlook.com addresses, so I have them all installed on Thunderbird.

Up until recently, it worked fine, although every few months Outlook.com would not allow the sync because of some security issue (wanting an alternative email address, wanting an alternative phone number, wanting me to confirm that the last sync was me). I would sign in to the email account on a browser, fix the issue, and then it would work again.

As of a few days ago, Thunderbird is showing the "Login to account XXX failed" and "Login to server outlook.office365.com with username XXX failed" for maybe a dozen of the addresses every time I open Thunderbird. If I login to the email on a browser, and force Thunderbird to "Retry" several times, it will sync the account - but the next day, the same issue arises with the same account. When I check the account activity, it shows successful automatic syncs.

Is there another setting I need to check or change to make Thunderbird work with Outlook.com addresses?

I installed TB 115 portable to review it. I now have it all setup and configured to my liking. Now I want replace my installed v102 with the new portable ver. My plan is to upgrade to installed from 102 to 115.5.2 (same as portable). But what files/directories do I need to move to do this? I have the Installed ver on C: (Win10) and the portable on D: .

Road map please.

Hi,

I did backup on my emails locally in my laptop, because I should migrate the website from one to another hosting and now I have problem with the emails after importing them, they are not visible.

How can help me with it? Looking forward for your help.

Best Regards, Rosana

moved thunderbird 115.6.1 from windows 7 to windows 10 and i can receive and forward new emails in win 10 but can not send new emails in windows 10. What do you think?’

I'm just getting started with Thunderbird on Windows 10. To test it, I set up my yahoo IMAP account xxxxx777@yahoo.com using a yahoo app password. It worked fine, so I deleted that account and set up my 'real' yahoo IMAP account, which is xxxxx@yahoo.com, using another app password from Yahoo. This is a different yahoo account, so I needed to get another app password. Again, that account worked fine.

However I then chose to delete that account on Thunderbird and return to using my xxxxx777@yahoo.com yahoo IMAP account, by getting a new app password and following the Thunderbird instructions for setting up an account. The trouble is that Thunderbird is now connecting to my xxxxx@yahoo IMAP server and receiving those emails and folders instead of my xxxxx777@yahoo.com emails and folders. I have uninstalled and reinstalled Thunderbird and rebooted the computer. Thunderbird 'account settings' is correct.

The first tab in Thunderbird is "email- xxxxx777@yahoo.com", and the folders that follow are from my xxxxx@yahoo.com account. Each time I receive an email on my xxxxx@yahoo.com account, it shows up in Thunderbird under my xxxxx777@yahoo.com account.

I'm stumped.

Thanks, David

Before these last few fancy updates I didn't have any problem creating filters but, now I can not figure out how to do what used to be so simple. Is there any reference material that gives a detailed explanation on how to create a filter under the latest version of TB? In addition, none of my previous filters work!

I am trying to migrate from Mailspring to Thunderbird, yet have problems with adding my Google/Gmail accounts.

When I try to add a new account with my email and password, Thunderbird detects the IMAP details as follows: INCOMING SERVER Protocol: IMAP Hostname: imap.gmail.com Port: 993 Connection security: SSL/TLS Authentication method: OAuth2 Username: <my email>

OUTGOING SERVER Hostname: smtp.gmail.com Port: 465 Connection security: SSL/TLS Authentication method: OAuth2 Username: <my email>

When I then try to connect, I get the Google sign in popup, where I re-enter my password and grant the access via 2FA. Then, the screen to give Thunderbird read/write permissions for mail, calendar, etc. appears, I click "Allow", the popup closes and Thunderbird tells me: "Unable to log in at server. Probably wrong configuration, username or password."

I have checked other help articles; cookies are allowed, Thunderbird has no stored passwords for Google/Gmail, I have no overly protective antivirus software installed (only Windows Defender), I tried it with/without my VPN off.

I saw older articles mention allowing unsecure apps, yet this has been deprecated by Google in 2022 (I also tried "Password only" instead of "OAuth2", didn't work). I also never got an email from Google that a sign-in request was blocked (only the typical "Did you just sign in?").

Other (non-Google) accounts work fine in Thunderbird, and I only installed it today (so there should be no updates), while another Gmail account of mine doesn't work, either.

I am out of ideas what I could try to get my accounts to work... Can anyone help me?

From David, Top Ten Contributor: "I am trying to assist, but I don't grasp what you are experiencing, since it is not what I think of as threading. You're saying the folder is unthreaded, yet the messages appear threaded by subject. Maybe some other voluhteer on the forum will offer some insight."

All the threading help is oriented to something I can set on the menu bar that also includes Date, From, Size, etc. I wish my threading problem was that easy. Threading is not chosen, never has been. Then suddenly April 2, 2024 6:30pm est, all my e-mails that had a thread got threaded, with arrows showing up in the subject of the e-mails.

There is a symbol on a different bar with choices like Sort By --> Threaded or unthreaded. All this does is hide e-mails that are even threaded or unthreaded, but it shows that what happened to me is also called "threaded." The term "threaded" has two meanings or definitions or uses or whatever, which makes asking for help all the more difficult. People keep telling me about the menu when I have a choice of threading, not realizing, as I think David didn't, that threading is also elsewhere in the thunderbird software.

And when I choose to show threaded, that e-mail I was sending on April 2 does not show up, but if I search for the file, it does show up. So it is there, but invisible. This whole threading situation just gets worse and worse. I need that file in particular, as it happens.

Thanks to anyone who read all this.

Hello, I'm running 115.6.0 (64-bit) on Ubuntu Studio 20.04.6 LTS (Xfce, if that's important ?)

Because I have 10 (IMAP) accounts configured I normally run in "Unified Folders" mode and I was therefore in this mode when I upgraded.

If I select View | Folders | "All Folders" I get a tick-mark but if I then click somewhere else on the screen and go back the only tick is against "Unified Folders".

If I select "Recent Folders" , "Unread Folders", or "Favorite Folders" they are displayed and stay displayed.

I have tried deleting the various files in the Mail directory suggested by other solutions but they don't make a difference. I think I don't have a problem getting "Unified Folders" - I have the problem of NOT using "Unified Folders". . .

Any ideas ?

PS: Non of my IMAP accounts allow me to select a folder for "Sent"; "Archives"; "Drafts" or "Templates" in the "Copies & Folders" section. - The field is either "NO available folders" or is empty and has no drop-down list available.

My backup tool blew up due to 1000's of Thunderbird files being modified.

I can't tell if this was due to some kind of malware, or if Version 115.5.1 of Thunderbird went through the database/file structure and wholesale modified everything. If the former, I don't want to backup the files (yes, I have run BitDefender of the profile structure: all 125K files and it comes up clean). If the latter, and everything is operating as normal/expected, then I do. I have seen no issues with the operation of Thunderbird (which I love, BTW).

So, did Thunderbird change 1000's files that were otherwise not accessed by me? (see example in attachment)

I am currently running the Version 115.5.2 (64-bit) / December 11, 2023. I presume this event followed shortly after the installation of "Version 115.5.1, first offered to channel users on November 27, 2023."

I have two accounts with sbcglobal.net. One is still working when I use Mozilla Thunderbird to access my emails. The other just stopped working today. I can neither send nor receive my email messages in Thunderbird. I spoke to a sbcglobal.net rep and they said to contact Thunderbird, as the message I am getting says server error. Since I can access both accounts via the Internet, it is not sbcglobal.net's problem. The rep also mentioned that blocks of email accounts are being updated on their servers. Maybe Thunderbird needs to reconnect with yahoo and at&t, etc.???

trying to get email - got this error; How do I fix this?????????? Happening last few days.

my email: [edited] @yandex.com

Sending of password for user pizzipie did not succeed. Mail server pop.yandex.com responded: [AUTH] login failure or POP3 disabled, try later. sc=75IVcg0DLKo0_290005_

For some reason, whenever I have multiple tabs open in Thunderbird, it will seemingly randomly open a new window, interrupting whatever I'm doing. What seems to happen is that the new window will contain the tab I was working with (address book, settings, etc.) and a tab for my mail, but that mail tab will have switched to a different mailbox. And then the new window that opened behind the other one will have a tab for my mail focusing on whichever mailbox was selected before.

This is driving me absolutely crazy! It keeps interrupting what I'm doing and makes me anxious to do anything in any tabs in Thunderbird. I need to fix it!

Any idea why this is happening and what I can do to stop it?

Thunderbird recently updated to ver. 115.6.0, after that it seemes that my configuration got lost: I cannot get contact to my mail at the provider. My settings are as stated by the provided as a pop3 account with the right settings. Worst of all is that my files used under the former version have gone lost, too. Is there any way to return to the former version of Thunderbird or is there another way to find my files? Regards Jens Madsen

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)
