Thunderbird Support Forum

I'm getting login issues to my Outlook account. I understand this is an emerging problem and I"m following the instructions here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

However, I can't follow the instructions under section "Change Thunderbird authentication method for sending messages (SMTP)" because I don't have "Outgoing Server (SNMP)" in the lefthand side. I do have an option to edit Outgoing Server settings, but there is no option to set OAuth2 in the Authentication Method dropdown. I am unable to send Outlook emails, and I'm unable to complete the instructions to fix it. Help is appreciated!

Dear sirs,

I believe that Thunderbird is one of the best email client programs available. This believe is the reason that i am trying to migrate to your email software. Sadly i have been experiencing a some dificulties on my main machine. I’ve tried for several times configurating the email on thunderbird, with sucess. The problem resides on every time that i close the program or restart my computer my email account vanishes from thunderbird. I am using an exchange2019 mail box. Could you please help me out with this situation.

Besr regards, Joaquim Nunes

Has anyone seen a message similar to this when trying to attach a document, usually a pdf to an email?

O:\XXXXXXXXXX.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences.

Also, when someone send me an image file, I can't open it directly from the email. I have to download it and then open it. This isn't as big of an issue as the above, but I thought I'd ask it too.

Thank you

Windows 10 Thunderbird 115.10.0

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

Anytime I attempt to send an email in the CCC ONE application, I get this error message from CCC ONE:

"Unable to perform selected action while the email application is open. Please close your email application and try again."

This error message persists whether I do have Thunderbird open or not. I also checked Task manager while I had Thunderbird closed and found no instance of it running. Is there any way that Thunderbird is running in the background? Or could it be if Thunderbird loads at start up that it's tricking CCC into thinking it's open all the time?

I contacted CCC ONE report and they advised me to attempt to change the name of a DLL file so a new one would be created to replace it. I tried that, the issue still persists. They also told me to try and uninstall and reinstall Thunderbird, which I did, and it still won't work.

Any ideas on how to fix this?

Sending emails hit and miss. Sometime goes right out, other times I get this "The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. How do I cure this.. keep in mind I am very close to computer illiterate..

Thunderbird - Problem

My email address is: finnvebirk@webspeed.dk (alias: evab@webspeed.dk ) I have used Thunderbird email for many years. I have archive folders with more than 50 folders and sub-folders. Overall, I have several thousand emails in my archive folders.

After I wanted to create a sub-folder and move it to another location, the following has happened: All my folders and sub-folders are mixed together and arranged in a changed order. All emails in my archive folders and sub-folders have disappeared - all folders are completely empty. I think maybe a folder called 'Local folders' has disappeared. It is no longer possible to move emails from the Inbox to the empty folders. NOTE: Inbox, Sent and Trash still works.

Question-1: What happened ? What can I do ? Can I recover all my emails in the archive folders ?

Question-2: Can I restore my Thunderbird mail system as it was, e.g. 2 weeks ago ?

Question-3: As an emergency plan (if all my emails are lost !): Can I reset Thunderbird without deleting mails in Inbox, Sent and Trash ? If Yes – How do I do that ?

top - left "get messages". either the button or on the account right click and get messages.

its been one or 2 days now that i press either and also on TWO DIFFERENT PC running win 10 and 115.9.0 version and nothing happens! doesnt get any messages. dont even get the Checking notification on the bottom left. auto message retrieve doesnt work either no matter the time period. its like i am clicking on empty space... a while after, just by itself, it starts downloading again.

Today I tried to look up a previous email that I'd filed in a subfolder, but the folder displayed no emails. If I click on the subfolder above it, it shows me the number of emails and displays the list of emails. Then when I click on the subfolder I want, it displays the name and number of emails for the previous subfolder I looked at.

I tried troubleshoot mode, but still no luck, and the folder is gray instead of yellow like all the others.

I'm using Thunderbird 115.9.0 (32 bit), Windows 11 Home 64-bit.

I've been using Thunderbird for years and have never had this problem before.

Hoping someone will have some advice!

why om last updates all my hotmail accounts keep asking me for passwords ? everytime i need to login... your older version was best then this.. i think you make updates with problems , how can i get the older version only ?

Have used a Onetel e-mail account for a number of years.

Occasionally, the outgoing server drops out so messages can't be sent only received.

When trying to reconfigure with correct port numbers etc it will never reconnect straight away and there is always a long process to get it up and running again which always seems different every time.

I can never manage this by myself and always have to get help in. This has baffled the best brains in the business so any help or advice gratefully received.

TB v115.8.0 (64-bit) Closed the app and went to dinner Came back and opened the app. All the tasks are GONE!!!

I know TB keeps everything in text files, so I found the "calendar-data" folder and opened some files using NOTEPAD.EXE to find keywords I know represent my tasks. Sure enough, the data is there in the sqlite files.

What's the secret code that simply decides to not open those files and populate my task window?

I have had message filters set up for a long time. Recently I tried to make some changes (adding one filter, deleting others, changing the response). I find that if I close Thunderbird and reopen it, all my changes are gone! How can I get the filter changes to stick?

I am going crazy. This message keeps popping up every time I turn on my Thunderbird email program on my Windows 10 laptop! Please see the attached file. I shows you the popup and what happens when I click on 'Next'. I 'x' it off, and a few seconds later it pops up again. The only way to stop it from doing so is to turn off my Thunerbird program. I like to keep it on so I know when I get emails. PLEASE help me get rid of this. Thanks so much.

Previously, for years, selecting and deleting groups of emails took only seconds. For sometime now, the more emails selected to delete as a group causes the amount of time to do so to become longer and longer. Minutes go by. It feels like instead of dealing with all of them at once, it's deleting one at a time, but that's just a guess. What can I do to get back to where it used to be? Thank you.

Symptom:

1. TB stopped downloading new emails for one account on PC.

Solutions Tried without success:

1. Checked Email configuration and settings 2. Restart TB 3. Rebuild Global Database by deleting global-messages-db.sqlite file. 4. Delete Saved passwords. 5. Delete all emails on webserver dating back to when problem began. 6. Change password on webserver.

Additional information.

Current version of TB: Version 115.9.0 Windows Version: Windows 10 Home 22H2 Email Webserver: Ionos Email Protocol: POP3

Issue Details: I use TB on my desktop to manage many different email accounts. Some from Gmail and some from Ionos. Last week, TB stopped downloading emails from one of my Ionos accounts. It still downloads from my other Ionos account and my gmail accounts. I use Aquamail on my Android device and it continues to be able to download emails for this same account. Additionally, I have a laptop with TB and it continues to download emails from this account without issue.

If you need additional information, please ask. Suggesting switching to IMAP is not useful and not a solution to my issue. I respectfully request that you Please do not go there (been down this road before). I want to fix the problem, not go around it.

Thunderbird continues to lose my password for incoming and outgoing mail. Occasionally it works, but I keep getting messages that my password doesn't work / enter new password. When I go to passwords, it does not show the incoming or outgoing servers so I can make sure my password is there. I use Xfinity for my email. It was suggested earlier that it is an Xfinity problem. My Thunderbird email is essentially unuseable. I need it to work!
