Recently, the Thunderbird email product quit working propertly. It requires me to log into the account each time I wish to open an email. This has been happening for the last week to 10 days. I have to reenter my password each time. Example, I open an email after logging in for the whatever many times it has been during the day, and I need to answer the email but need to get some information first. I go get the information and the email program requies me to log in again, even if it has been just a few minutes. This has not happened in the past. I have been using Thunderbird for a very long time, many many years and never had this happen before. I loaded the program on my laptop that I use when I travel or am not at home. Same thing happens with it.

This is highly frustrating and time wasting to have to do that. There is nothing I have found that shows me how to address this. My phone has a different email program and that does not happen when using the phone. And like I said, I have been using this email program for a very long time and have not experienced this in the past.

Is there access to a user's manual or some quick guide to help me with this? I am not a tech newby, but I'm not an IT professional either, which was why I choose using Thunderbird many years ago. It seemed user friendly at that time.

Thank you kindly for your help. Ken

I used to be able to download with no problems. I did not change any settings, but now I can’t download any emails from either of my accounts.

I have email with shaw.ca and telusplanet.net (now operating under gmail). Neither one will download

When I try to connect it gets hung up on: Host contacted, sending login information . . .

After a while it used to come back with a comment about login to server failed

I have tried under 3 difference wifi/ethernet networks I’ve tried under wifi as well as direct Ethernet connection I use Windows 10 and it is up to date Thunderbird is up to date I use the POP method I’ve tried using a smaller password I have changed from SSL/TLS to STARTTLS and back I’ve tried using different ports (995 and 110) I use AVG and have tried it with AVG options turned off I have AVG configured to allow in and out for Thunderbird I use Normal password as the authentication method

What else can I do?

For a week, I have not been able to send any emails through Thunderbird.

This is the only day that I have been able to delve further into the problem.

If I send an email, this is the response that I get after sending. Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I have contacted my main provider and they have been useless. I contacted my secondary provider and they sent me what the settings should be. I checked their info against mine and everything is correct.

I prefer Mozilla products over all others and I wish to get this corrected sooner later, I have two assignments to send over the weekend.

I would rather being doing something else that trying to figure out this problem.

I should be celebrating or mourning the passing of my wife 3 years ago, than trying to figure out what is wrong.

One thing I did do was to go to the Mozilla website and download Thunderbird again in case there was a conflict somewhere in the system.

Thanking you in advance. K

My 'sent', 'All Mail', 'Spam'; and 'draft' and 'templates' folders in my gmail account in Thunderbird have suddenly disappeared My other account looks fine, as is my husband's account I have deleted the account from thunderbird and reloaded it but it remains the same. My gmail account on my ipad and iphone still have the all correct folders in place Can you help please - ?

Just installed latest Thunderbird version 128.5.2. Previously using a very old 78.5 version for many years. I now have a row of buttons on the toolbar at the very top. The first button is "Get Messages." When I first open Thunderbird and click that button, nothing happens. If I right click that button I see two options. One is to "Get All New Messages" and the other is the name of my only account. If I click the "Get All New Messages" option, it still does not work. If I click the name of my account, it proceeds to asks for my password and look for new messages. There is also a small button that looks like a cloud with a down arrow below Menu Bar under the word File. That is also used to Get Messages. When I click that button after first opening Thunderbird, it works. It asks for my password and looks for new messages. The odd thing is this. After I get it to work the first time and I type in my password and it look for new messages, then the "Get Messages" button at the top that did not work at first now works. So when first open Thunderbird that button does not work to do the first check for new mail. After using the cloud icon the do the first check when first opening Thunderbird, then the larger button at the top works. Anyone know why it works this way? Thanks, Tim

Can't this problem be solved, the other clients are doing well :man-shrugging:

I wanted to say thank you, but the post is in the archive. https://support.mozilla.org/en-US/questions/1197767

Thank you very much!

The year is 2025, version TB 128.6.0esr (64-bit), and your solution is working!!! This is a real problem, IMHO! I looked at the TB at lunch, there was no letter, I look at the letter in the evening and he writes to me that it arrived at lunch. It looks like I’m blind :(

I've been using T-bird for a couple of years without a problem. A couple of months ago, T-bird started sending me error messages and no longer sent outgoing mail. I checked with Spectrum (my main mail provider for email: mad1doc@twcny.rr.com) and it looks like all my settings are correct. I have 2 other Gmail accounts and they both work perfectly. I'm including a screenshot of the most recent error message / server refusal. What do I have to do to fix my RR email account?

HI.... HELP...Got Hacked... All of a sudden, starting a week ago, I get 60 and more, unwanted E Mails from people I don't know, & have to go thru & delete them daily.. I have a list of my true correspondents & can re enter them, if there is some way of one time, emptying the Input box or what ever, to stop this from happening, every day...........Thanks. Ken

I've tried Troubleshooting Mode but it only recommends "Clear Startup Cache" and when I click it to reboot the program Thunderbird stills fails to load the Inbox file and Troubleshooting Mode again recommends the same "Clear Startup Cache" as a remedy. Not sure what to do to get Inbox file loaded in program. BTW the program does download new emails to the Inbox file but program is unable to load the file. During Thunderbird program restart the message at the bottom left of Thunderbird window is "Summarizing files for Inbox" which after 20 minutes program crashes ans asks for a reboot. Any corrective action recommendations is appreciated.

Thanks, Mike

Not sure when it changed but I remember being able to add a new email address when creating a new email by opening the address book and dragging. There may have also been the ability to right click on the address in the new email or from an email in the Sent folder and 'add to contacts or list'. Not sure of the wording.

Has something changed? I can seem to accomplish this without copying the email address then opening the address book and adding it manually to my contacts. Even when the contacts side bars is opened in the new mail window with F9 you can only select from existing, not add to the contacts from the TO: address.

Thanks

I need to change my password however I am not succeeding.

I am trying to change it from the following path : Settings - Saved Passwords.

Once in the above path, I type in my new password and press close.

I then close thunderbird and when re-opened a pop up window appears to type in the password. When typing in the new password, the following error comes up:

Login to server secure.emailsrvr.com with username ------------- failed.

For thunderbird to continue working, I need to enter my current 'old' password. Somehow it is not recognising the new password.

Can someone please help ?

Since I updated this version, Thunderbird often fails to connect to the mail server. And sending mail is very slow.

I don't know why, is it because I use VPN? Do I need to set Thunderbird to use the system proxy to connect to the Internet? I used automatic detection before.

I was advised to change from Pop to Imap I have 3 gmail accounts, & all 3 now have Imap in brackets after the name. 2 are no problem but my main default account has two occurrences, the Imap one I can open with no problem but every time I open Thunderbird this message pops up " The STAT command did not succeed. Error getting message number and sizes. Mail server imap.gmail.com responded:[SYS/PERM] Your account is not enabled for Pop access. Please visit your gmail settings and enable your account for Pop access". Is there anyway I can sort this out, or do I just ignore it? Please don't be too technical I am 81 & struggling with technology!

I have to change my email accounts by the end of the year. I've been manually moving folders and emails from old account to the new. Then I would like to copy 'Message Filter' from the first account to the next.

Is there a guide or an app to do this? The Message Filter is probably the most important thing I need to do.

All of the sudden today I can't send email from Thunderbird. Incoming email fine. However whenever I try to send I get a server timeout error. This has been working fine for years up until today. This is the message; Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtphm.sympatico.ca timed out. Try again.
