I-Thunderbird Isithangami Sokwesekwa

I can't send emails out of Thunderbird but can receive them, not sure what to do? Is there a phone number I can call with Thunderbird for help? I'm not that savvy with all this.

Struggling with TB constantly "downloading" x 10s of thousands of 10s of thousands of emails (all of which are downloaded), and the programme grinding to a halt. Have set the inboxes to a retention policy of 2500 total. So shouldn't even be trying to DL more than that. Seems to mainly manifest when I compose an email (exactly the time that the sluggishness is a problem). Have done the usual compacting/deleting * files.

This is getting to be a real issue now. I wonder if there's any paid support channels that can deal with this?

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

With just 2 email addresses that I have been using for years, I suddenly get this Undeliverable message when attempting to send emails using Thunderbird:

"The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT"

I can receive emails from the 2 addresses fine, I just can't send to them through Thunderbird. When I sign in to Hotmail Outlook Live I can send and receive to these addresses with no problem.

I'm stumped! Any ideas? Can I reset Thunderbird?

Thanks

I've been a faithful Thunderbird user since the beginning - and continue to use Thunderbird with our company's Microsoft365 deployment

until Monday of this week -- when suddenly I find that my credentials are being refused.

The symptoms

• XXX: Connected to outlook.office365.com
• nothing in the activity viewer
• no email coming in

I've read and tried all the fixes proposed in the article at https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 (restarting thunderbird after each step, naturally)

• have authorized Thunderbird to our Microsoft365 tenant
• created and tried registering with a new thunderbird profile
• have set my security settings to 'accept all cookies'
• have used the config editor to remove 'oauth2.issuer' and 'oauth2.scope' values
• I've checked that my account in Microsoft365 has IMAP and Authenticated SMTP enabled

So, since Monday, I've been living in hell, trying to pretend that the Microsoft Outlook app for macOS is useable, but it's practically debilitating to be forced to use that piece of software.

Can somebody please point me to another possible set of steps that I can use to try and diagnose this?

I absolutely hate myself for having to ask for help on this, but I'm at my wit's end...

Hello! Windows 11 22H2 22621.1555 + Thunderbird 102.10.1 (64-bit) I face a problem with Yandex mailbox with the following authentication settings: smtp.yandex.com:465 SSL/TLS OAuth2 The "Enter credentials" window gives --- 400 redirect_uri does not match the Callback URL defined for the client --- after logging into account. The address in the window is https://oauth.yandex.com/authorize?response_type=code&client_id=...&redirect_uri=http%3A%2F%2Flocalhost&scope=mail%3Aimap_full I removed the client_id but "localhost" is authentic and suspicious. What can cause the problem?

Keeping got massage: The folder 'Inbox on parkerlin@hochien.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

Have clean up all In box mail and compacted it, but still has same problem .

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.

What can I do?

Good morning

My client uses Thunderbird as the default mail client. I have setup SMTP in the Sage ERP system as the email configuration.

If we send email from Sage, Thunderbird crashes, however, the email does send though. If we reopen Thunderbird, it continues to work, but crashes again, once an email is sent from Sage. Error code: bp-cfdfe3a3-9c4d-487d-9a10-e59510230413

What could cause this and do you have any possible solutions?

Kind regards Maritza [removed phone# from public forum]

I had Thunderbird automatically upgraded to 115. Since then I only see the new emails, all folders and emails from September 12th, 2023 have disappeared. Unfortunately, the restore command doesn't help with MozBackup either; it is executed but with no result. Please describe to me step by step how I can restore the folders and emails.

In this folder: C:\Users\kschl\AppData\Roaming\Thunderbird is just an old profile. Therefore, I wanted to use a backup via MozBackup to restore all data, unfortunately this doesn't work. An initial comparison of the newly created profile also shows the folders, but they are not displayed in Thunderbird - there is an incorrect setting.

Please describe this to me step by step, including in which directory I should store the backup in the future.

I have been using Thunderbird for years to access several @charter.net email addresses, lately administrated at Spectrum, which took over Charter. Everything was working normally until today. I can still receive emails, but when I send, I get an error message asking for a password: "password required for outgoing SMPT server" Manually entering a password in that error message box doesn't help. Spectrum support is not helpful beyond confirming that my email sends and receives normally as long as I access it on their website. Three clues: 1) Spectrum recently announced "new and improved" email. 2) One customer service person described my email addresses as "legacy". 3) My gmail address sends and receives just fine from Thunderbird as usual. Any insights appreciated! Thanks!

For past 24 hours only, I have been unable to open email attachments. v115.7.0, however last update was 31/01 and has worked perfectly until now. Still use Windows 10.

Double clicking on attachments does nothing, other than popup software option for formats without specified defaults. Either way, no indication that attachment is opening.

"Save as" is saving attachment document to target folder, however trying to open these errors, suggesting document is corrupted or in incorrect format.

Have tried restarting system to no effect; likewise error continuing in troubleshoot mode. Cannot see any obvious settings that would impact this, nor have I consciously altered any of these.

I'm certain this may be an easy fix, or my own error, but this is eluding me.

My wife's C; drive is nearly full, and part of the problem is the TB Roaming folder under AppData under Users. On my PC this folder is 16MB, but on my wife's is over 35GB!

How can I reduce the size of this folder?

thanks,

I am unable to send messages from Thunderbird This is the error message I receive

Sending of the message failed. An error occurred while sending mail: Unable to establish a secure link with Outgoing server (SMTP) smtp.telstra.com using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.

I am not tech savvy so dont know what to do to fix it

After changing my password I get the following error message: "Server imap.pt.lu has disconnected. The server may have gone down or there may be a network problem" Thunderbird is running well on my mobile, so why not on my PC? I have tried these things: Internet connection is working (as you can see from this mail) I have checked server settings, they seem okay. I have deinstalled and reinstalled Thunderbird. All to no avail. Can you help me?

Hi everyone, I am far from a proficient T-bird user so stick with me... My C. drive has a massive amount of space being used by T-bird, over 67Gb. My account is the only one on this machine and it is hosted with Inmotion Hosting. I've confirmed with them that they see me as an IMAP account and my settings are IMAP also locally. I did find under settings in Sync and storage a setting for 'Keep messages in all folders for this account on this computer'. The check mark is checked so it will be keeping all messages. Under Advanced (to choose which folders are 'kept' locally, there are options for all of my folders, some are back to 2014. My question is if I uncheck this box so that the files are not kept locally, will it for some reason expunge the files from the servers within Inmotion? My hesitation is due to talking to them about 14 months ago and I was given erroneous info on POP vs IMAP and subsequently some emails being lost on a corrupt PC. I'm a bit gun shy to execute the unchecking and then the delete of the huge local file.

File path is:: C:\Users\Practice Manager\AppData\Roaming\Thunderbird\Profiles\kn769u8t.default-release\ImapMail\secure251.inmotionhosting.com

The secure251.inmotionhosting.com is the big pig with 65.4Gb.

Any insights and help would be greatly appreciated.
