Thunderbird Support Forum

Greetings: This is the third time that I am contacting you about not being able to receive any e-mails. Thunderbird is the only one that I use and haven't been able to receive any new e-mails for the past week or so. You notified me that my account had been compromised or words to that effect, and that I needed to create a new password. I did this(with a bit of difficulty) and still have no new e-mails coming in to this account. I did try to SEND an e-mail out, and at first it stopped me for my NEW password. I gave it, and it then allowed the e-mail to go out just fine. I sent one or two more since then and they too seemed to have worked fine. For some unknown reason though, I STILL am NOT receiving any new e-mails. Can you please help me with this problem? NOTE: As I am STILL NOT able to receive any e-mails, would it be possible for you to send me any possible solution for this problem via my regular USPS mailing address? David Beard [removed address info from public support forum] Thanks much for any help you can supply.

Hello We are trying to set up an email client Mozilla Thunderbird, but nothing works, because the email client does not have enough fields that are specified by the provider, here is a letter from them:

Hello,

Your SparkPost account is configured correctly. I recommend contacting Mozilla Thunderbird support to see where you can enter the required fields in their SMTP client to connect to SparkPost. You can see the full client configuration steps here: https://developers.sparkpost.com/api/smtp/

They should be able to prove the steps to get these settings configured in their SMTP client.

Please let me know if you have any questions; I will gladly help!

I can't paste the link I get from Dropbox to connect FileLink for Dropbox into my settings. Why not? Even when I type the very long string by hand, it will not connect. What am I doing wrong? Is there a step I am missing? I really need this feature. Thanks- Pat Stoll

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

Hi,

I am running Thunderbird 115.10.1 (Flatpak) on Ubuntu 20.04. (no extensions except birdtray) I have 4 email addresses added to my TB, and I like to see all of them together, therefore I am using Unified Folders. When I am accessing Unified Inbox, TB is very slow and basically frozen until it loads this folder (often a pop-up appears that 'TB is not responding'). it takes between 30-60 seconds to load my emails (either on start-up, or clicking on another folder, then going back to Unified Inbox). Every other folders open almost instantly. I have to admit I have a lot of emails in the Unified Inbox (~20K), however the inbox of my main email has 18K, and accessing that folder separately is instant. So any operation, other than opening Unified Inbox, is quite snappy.

This issue persists since I upgraded to v115, even when I did an OS reinstall (also tried installing apt (v115.11.0)).

I have seen this answer: https://support.mozilla.org/en-US/questions/1428374#question-reply however, nothing changed by resetting the folder.

I recently lived thru the Cox-Yahoo conversion. Yahoo webmail has a folder called SPAM..where all the what I call JUNK goes to but in TB but it never gets into the TB JUNK folder..I can only see it on webmail Yahoo..How do I point the TB JUNK to link with this SPAM Yahoo folder please?

All the gmail entries & passwords deleted, remaining email passwords replaced, as of this morning.

I replaced them, and then so did they. I just yesterday deleted my online life... I'm sure just a coincidence.

Here's half of one they used: M.C555_BAY.0.U.-Co2UA6qeq4JOFgsvOCkdA**pHYS5XqT3TfRXLZAdnUxGM361xXXF0iCTeAaY5pXNyRoEu7KvIh3*uCkYXNAKRvbL7UnBYVnODYaRQ8e5lPvftncJgK1yNc9TzeqTMW1BCwqdeBAjmbGg

Suggestions? (Other than accept the dark side & sell your soul)

So I just changed hosting companies and now I can't access ANY of my emails in Thunderbird to change my incoming and outgoing server settings because the failed login messages keep coming up so fast I can't get past them. I can't be the only one who's ever had this happen. Is there a workaround?

Hi – I have been with Thunderbird for a while now but didn’t use your email program as I have been using Gmail for several years and still do. When I finished with my previous ISP, I copied the folders holding all my old emails to the hard disk on my PC. Is there any way I can use Thunderbird to read/delete these emails using my hard drive as the source and without using an ISP?

Very soon after startup it begins to stutter with the spinning beachball of unresponsiveness. At first it will spin, then come back for a few seconds, then spin again. Eventually the whole app is unresponsive.

The troubleshooting steps I see on here all start with "Go to [some location in the menu]". I can't do anything with anything in Thunderbird. I can force it to quit and start it up again, that's about it.

It is also always asking me for the passwords of some of my IMAP accounts. These are big accounts, some folders have several hundred thousand emails. The Inboxes are smaller, maybe a couple hundred in total at the moment. The last configuration I was able to make put it into Unified mode.

The damn thing is that after having been useless like this ever since I installed it, last week it started to work fine. Stayed that way for several days. Eventually that failed, though, and my whole Mac ended up locked up the way the app is, I had to manually power it off.

I don't know if it writes any info about what it's doing to a log file somewhere, I am not having much luck trying to find any information here. Just other people with similar problems but no substantive replies.

Using Thunderbird on an older Mac laptop, running macOS Monterey 12.7.5.

While managing my Thunderbird Inbox, I inadvertantly transferred a chunk of Inbox messages received from my MS Office365 Outlook account into the trash. I went into Outlook on the WebApp and discovered that all of the inadvertantly deleted emails were found under recover deleted emails. So within Outlook I recovered all mails into the Inbox. So far, so good.

Now I have all the mails listed in the Inbox on Outlook. But when I open Thunderbird again, the recovered mails do not show up. It seems that Thunderbird does not fully synchronize the folder and the recovered emails are not downloaded. Instead, all mails are once again removed from the Outlook Inbox. The previously recovered mails disappear again from the inbox of OWA and I have to recover them all again.

I have already tried several fixes. Within Outlook, I created a new folder and moved the recovered Inbox mails to that folder. This was done in the hope that this folder will then sync properly with Thunderbird. Unfortunately no. The folder does not sync and as soon as Thunderbird is closed again, all mails are deleted again from the new folder on OWA.

I also deleted the Outlook account (including all stored data) and recreated the account in Thunderbird. Unfortunately, the same thing happens again. The recovered mails are not displayed in Thunderbird and after closing the program, the mails are deleted again in OWA and I have to recover them again. Finally I went so far as to uninstall Thunderbird completely from my computer and reinstalled the software. That did not fix the problem either.

I will also provide another observation: in the past when I have recovered individual emails the same behavior has occurred. Seems that when Outlook or Exchange places a deleted email into the recovery queue, there is a change in its identify such that TB now views it as a deleted message.

Any suggestions on how this can be fixed?

Best regards

v115.10.1 I made a mistake setting SMTP credentials, wrong protocol, and it just stays on Sending dialog. So I abort when I realize I made a mistake and come back to mail I was to send. - but 30-60s after I aborted comes an error message saying it timed out

So the cancel button does not really cancel the send attempt, it seems.

Not sure where to report bugs, so do it here. Thanks.

v115.10.1 32-bit Changed isp and email completely, and wanted to change both server name and user name. But editing server name and leaving that field I get a popup wanting to restart - problem is I need to change user name as well or no go

So it starts to try and login but fails of course, since user name need to change too.

This really need another approach, maybe not so automatic.

Changing focus from first field to next one should not execute restart. - just when leaving second field if any of first and second is changed

So going through all accounts and failed logins etc all the way is cumbersome. - dual restarts every account

Not sure where to put bug reports like this. Thanks.

Now and then, when I press the Enter key, Thunderbird moves the current email message from Inbox to Trash instead of opening the message in a new tab.

I am using Version 115.11.1 (32-bit) on Windows 11.
