My Thunderbird (158 Meadow) is very slow sending emails. Up to 30 seconds for an ordinary message. Most often thew people are in my address book but even if they are no the problem is common across all outgoing emails. Windows 11 Laptop 26H2, 64Gb Ram, 500Gb SSD, 200GB free, i7 (12 Edition) Intel I have already checked that my Windows Defender antivirus has the profile folder as an "exception" Compressed my "send" folder Run "repair" on my send folder I have about 500 emails in my send folder I have an IMAP set up with SMTP set to 465 SSL/TLS Normal password I have checked my webmail and that works fine so it is not a problem with hosting etc.

Hello there,

With one of the email addresses I am montoring on Thunderbird I experience an unusual difficulty.

There are times, I get to see a pop-up window that the login failed, and being prompted to enter the password again.

I've learned that in those instances I need to remove the password from the password list in thunderbird, restart my laptop, and in opening the thunderbird dashboard re-enter the password, and then it's fixed.

Today, however I keep repeating this procedure time and time again, but this time it doesn't fix the issue, and this pop-up message keeps popping up, each time enter the new password.

Is there anyone who can help me resolve this issue ? ...

That would be great, because since the login fails, I am unable to receive any incoming mails of, nor send any from that account in thunderbird.

Kind regards, Christiaano

After a lot of research, I thought I had the filter issue conquered. I perhaps made them too complicated, using several "match any of the following" by using the plus sign and entering into the second window which appears. I used "match any of the following" For "from" I chose "from, subject, cc".

After creating a zillion of them, I wanted to edit one or more and when I click "edit" I get:

"This filter was probably created by a newer or incompatible version of Thunderbird. You cannot enable this filter because we don’t know how to apply it." Using 151.0 (64-bit) Thanks....

Situation: Several Earthlink accounts using IMAP in Thunderbird. Earthlink/mindspring folders show the same folders as webmail. However, Thunderbird includes (by default?) "Sent Spam" and "Virus Blocker" folders. These are not visible in Earthlink webmail.

The folder subscribe function doesn't appear to do anything.

Deleting the msf files from the profile and restarting Thunderbird recreates the MSF files, and the empty, non-existent (on webmail) folders persist.

Have had this issue for a very long time. Would like to know, just to assuage a tiny bit of OCD, how to remove the folders from the list displayed for the account(s) on Thunderbird.

Thanks in advance. M

I am unable to access my emails in Thunderbird. Thunderbird opened but does not respond as there appear to be some files /emails that it could not accessed.

I tried deleting the Parent.lock file. I then deleted Thunderbird and re-installed it.

On opening the updated instance, it comes up with the same couple of files/emails in the list. With the same ones seemingly trying to be loaded. See attachment. The files are Invoice 03-10-20 and Ticket_1.pdf

I've received the following message the last few days when I send an email with Thunderbird:

Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. (I am sure neither of those errors apply.)

It then gave me the option to "save" (I didn't get the exact wording before I clicked on "save") and I don't see it anywhere. This was a very important email and I need to find it.

I have now the version 158.01 (64-bit) with Windows 11. My Gmail account only dowloads email like once a day. The server settings are: -Check for new messages at startup -Check for new messages every 10 minutes This started a few days ago, while I had the version 158.00. I have many accounts on Thunderbird, and re-installing all of them would be time consuming. Any suggestion?

I have configured the message columns in the Message List pane for all the folders the way I want them. Unfortunately, Thunderbird frequently changes the columns in some, but not all, of the folders back to the default column configuration.

To temporarily fix this, I click on the column picker button in the folder that has the column configuration I want and select "Apply columns to > Folders and its children > " my top level folder. I also repeat this and select "Apply current view to > Folders and its children >" my top level folder. Sometimes this corrects the column organization in all my folders, but I usually have to repeat the above procedure multiple times to get the columns arranged the way I want them in ALL my folders. This lasts a few days before Thunderbird again returns the message columns in SOME of my folders to the default configuration. I then have to repeat the above procedure multiple times to get them the way I want, only to have to do this again in a few days.

How do I stop Thunderbird from making these changes, or how do I change the default column setting to the way I want it, not the way Thunderbird wants it?

This is not a new issue for me. I've been dealing with this for quite some time over many Thunderbird versions.

I'm relatively new to Thunderbird and have discovered that all folders are configured for threading by default. Threading is something I don't care for at all. I've found one article that addresses this issue but the process outlined is ponderously byzantine. I'm hoping this has been simplified since that process was published. How do I turn off threading on all existing and future folders? Thanks for any comments.

Have got a replacement computer, and downloaded the latest TBird (having used it with AOL) for years). Following initial set up procedure, TB detects correct settings for AOL and the "enter password" page opens from AOL succcessfully for authorisation. AOL requires 2 factor authorisation, and I use a phone code for this.

However the speed at which the code arrives from AOL has always varied quite a bit, and today it is taking almost a minute so the TB set up screen is timing out long before the code arrives. Cant go on retrying as I will get locked out of the account. No point in going for manual set up as the auto settings are correct, so the same problem is going to occur. I have three AOL e-mail addresses to set up! Is there a workaround of some sort for this - its terribly frustrating and the set up screen "connect your e-mail settings" timeout period does seem quite short if you have to wait for a 2FA phone code or e-mail code - any delay in the arrival of which is completely ouside your control .

Hello,

I'm moving to Graph from EWS and have followed the instructions at: https://support.mozilla.org/en-US/kb/microsoft-ews-graph-migration

I get through to screen that offers Graph API as an option, alongside IMAP, POP3 etc, and click on Graph API which directs me to my browser to log in to my email service (via GoDaddy). I log in successfully which takes me to the Thunderbird 'You're All Set' screen saying the account has been securely connected to Thunderbird and therefore ok to close that screen.

Back on Thunderbird it then progresses but returns with "Authentication Error - unable to log in at server. Probably wrong configuration, username or password".

The username and password are correct, and there aren't any other options available when editing/manually configuring the connection...so at a dead end, alas.

Any pointers much appreciated!

For years I have had two email addresses: - @virginmedia.com and an older @blueyonder.co.uk one - with no problems: POP is set up with the two servers pop3.virginmedia.com and pop3.blueyonder.co.uk. SMTP is set up with smtp.virginmedia.com for both. Everything was sweetness and light. I could receive and send from both accounts no problems.

Two weeks ago, the MF-505 relay refused error popped up when I tried to send an email from @blueyonder.co.uk and has continued to do so ever since. I can receive @blueyonder.co.uk emails with no problems. I can receive and send from @virginmedia.com with no problems. I can login to the virginmedia webmail site with @blueyonder.co.uk and send emails with no problems. Even so, I changed the @blueyonder.co.uk mail app password with Virginmedia just in case; no help. I have deleted the saved passwords and resaved them; no help. I have tried adding an @blueyonder.co.uk smtp outgoing server to Thunderbird even though I never had to before; no help. I have checked smtp server outgoing settings - even though everything works fine for @virginmedia.com. No problems there.

The general advice "out there" seems to be wait and it will resolve itself but it's been two weeks and for what it's worth Virginmedia confirm there is no problems with my account or their services their end.

any suggestions will be appreciated.

Upon startup Thunderbird downloads multiple copies of every email. A few days ago it was just 5 copies of each now it is 10 or 15 copies of each. Of course it then gives the disk full message. But this drive has over one Terabite of free space.' Been a user since Thunderbird inception and donated a few times but this and other iss are making it hard to stay loyal.

I use Thunderbird with a info@... account hosted by TransIP.

When I send an email, especially when I reply to a previous email and even more when this was my own email, the sent email is not always saved in the Sent folder: neither in the webmail of TransIP nor in Thunderbird. It seems random when emails are and are not saved in the Sent folder.

The replies are sent through; the recipient receives them.

What can I do?
