Suddenly getting error message window titled "Send Message Error" Reads" Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.peak.org failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

Checked with ISP and they have not blocked or many any changes and verified the SMTP settings are correct. Port 465 Connection Security SSL/TLS Authentication Method Normal Password.

I also at times received a Tbird window in the lower right of the screen that I couldn't using the snipping tool on to same. Says something about reducing the cache which I did to no avail, going from what I gather is a default 15 to 10.

Was sending messages without issue this morning but now can't get past the above message. Can send messages using the ISP's Zimbra webmail. They have no knowledge of Thunderbird and do not support it. I've read what I could find but didn't see anything replicating my issue.

About four days ago my email froze & asked for my password to activate imap.mail.yahoo.com. Everytime I enter my password it flags failed & asks for retry or new password. Finally I went directly to the yahoo mail site & logged in with the exact same password. If it works on yahoo mail but not on Thunderbird (anymore) I am at a loss. Can you help me? Thx, Doug

I have been using Thunderbird for a year. It is ok, but some problems are borderline un-tolerable. I have ~3500 emails in my IMAP account. I would like to keep more for a deeper search, but ok - I could handle that. And once in a while, about every month, I am doing something and the Thunderbird decides to re-download all my messages. And it locks me out of all emails for about 2 hours while this process is ongoing. I cannot open emails, I cannot answer - nothing.

I have no "cleaning" software, I do not mess up with the database file.

Is there a way to avoid this re-download? If not, is it possible to avoid the lock-out, to get emails usable while it does it - for example, download the most recent emails first and make them visible at least?

We use Mozilla for all our email accounts, and yesterday morning it temporarily crashed. We now can't access any gmail emails , apart from February 2024. Can you please help us retrieve our emails?

I have been using Thunderbird on my PC's for at least 8 years. It has been reliable and easy to set up for use with multiple acccounts. However, in the last couple of weeks it keeps freezing up and the header bar tells me it is "not responding". I have tried closing and reopening the program & restarting my computer, no joy. I wonder if there was an update recently which caused this sudden bug? My current version is 115.6.1

I have used message filters for some years with complete success. Recently when an email is moved by a filter, either on initial receipt or on manual run, the message appears in the correct folder okay but is not removed from the inbox. i.e. it appears in both. If I delete it from the inbox it gets deleted from the folder as well. !! I am not aware of having changed any settings. Can anyone explain where I'm going wrong, please? John

Thunderbird opens and is permanently trying to re-open a previous tab, with the oscillating dots. It will not respond while trying to do this. How can I close this tab?

Greetings, all,

I get this error messsage:

<We are unable to complete your request. Our system is currently unavailable.Please try again later.>

when i try to log on to my USAA bank accounts.

Tech support at the bank worked with me for an hour. We changed password, cleared the cache for the bank's apps, restarted Firefox, restarted the computer, all to no avail. I declined to try Google, simply because i don't trust it. Tech support person said another bank customer had had same problem and just changed browsers, which i don't want to do.

TIA for any help.

I am receiving the following message: The RETR command did not succeed. Error retrieving message. Mail server.comcast.net responded: Message 9 expunged.

The message number does change each time I try to download my messages. Thanks for any help. Rob

I think I have been scammmed I was sent an e-mail that appeared to be from cogeco.ca my provider stating that I needed to update otherwise I would no longer be able to get into my email account. I updated and now cannot get into my email I can get into everything else using firefox but not email, please help me. Thanks

Hi,

Hoping someone can help, I'm setting up my Gmail account and have copied all the settings over exactly from my old laptop and have generated a new 'app password' in Gmail. Thunderbird pops up a Google login page then it is saying it can't connect to the server. Everything is working fine on my old laptop with configuration exactly the same (except for the use of older but still active app password).

I don't think Google allows me to see my old app password, only generate a new one, but as the new one won't work I'm thinking that maybe Google somehow knows I'm using POP email on two machines and won't allow this until I delete the old app password. Does anyone have experience of this? Just don't want to delete the password in case it stops working on both laptops! Also note that I don't want to disable 2 step authentication as this makes my account less secure and it has been working fine for years with this enabled.

Thanks!

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

I keep getting a message that says on YouTube "experiencing interruptions, find out why?'. The videos pause and are choppy. When I click find out why, it's telling me to turn off my high resolution. I don't even know how to do this. My tower is connected to a samsung hd smart tv, that serves as my monitor. I have a wireless keyboard and mouse. The message is constant - all day long, every day. Can you please help me fix this problem. I am a paying member of YouTube Premium. Thank you.

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

I'm trying to send a reply e-mail and I get this message. "Sending of the message failed. A certificate that is not yet valid was used to issue the server's certificate. The configuration related to smtp.gmail.commust be corrected." What must I do or what can I do?
