Thunderbird Support Forum

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

Certain email newsletters that I signed up for (and verified) go directly to trash. I have no Thunderbird filters on nor does my internet or computer. How can I fix this? I switched from Outlook but sadly, will have to go back if this isn't fixed.

I have already several times asked my question and have received no reply so far. Could you please reply to my e-mail: jean-pierre.biber@natcons.ch Here my question again: Good evening I have been using Thunderbird mail for ages, and now suddenly diverse thing don't work anymore: I can't chose my signatures anymore, the language correction does not work anylonger, and when I print things they come out wrong. Can you please help me fix that? My email is jean-pierre.biber@natcons.ch Kind regards Jean-Pierre Biber

Back in 2015 someone asked about the fact that emails are not marked "as read" once opened but I don't think the answer was ever fully given. They were told: "This option has always been available and I use it. via Menu Bar Tools > Options > Advanced > Reading & Display or via menu icon menu icon > Options > Options > Advanced > Reading & Display select: 'automatically mark messages as read' Select: 'Immediately on display' click on OK When you select/left click an email in the list, it will auto open and display in the Message Pane below the list. If you use double click, it will auto open in a new tab or window depending upon what you selected. In bth instances the message will be immediately marked as read." Here's my problem with that .... I don't use the "Message Pane", I don't like it. I have my incoming messages set at "table view" and they are all just listed down the page by date. I don't want to see what's in the email until I actually open it....but, once I open it and read it when I close out of it the email still stays BOLD in the list....this didn't used to happen, once I read the email the BOLD went away. When I use the "automatically mark message as read immediately on display" then new emails are not in BOLD so I can't tell if they've been read or not. Bottom line, is there a way to have messages marked "read" AFTER they are opened WITHOUT using the message pane??

Suddenly I can not receive my emails on Thunderbird. They do show up on my cell phone. When I send an email, I get the following, "Your message was sent, but a copy was not placed in your Sent folder due to network or file access errors. What can I do?? Ed PS I will get your email response on my cell phone, thank you.

Thunderbird keeps erasing my inbox.

Today was the third time.

It has erased over 300 emails!

I currently have Thunderbird set up using POP but would like to change to IMAP to sync with my other devices. If I change from POP to IMAP, a. will that affect the emails that are currently showing in Thunderbird and b. will the emails that are in Thunderbird then appear with my other points of access?

I can't open my Excel attachments in ThunderBird.

Is there a setting I need to open. The one I use by default only gives me word, wordpad options. or choose my own, which is still word and wordpad.

Thanks for any help.

I'm using ThunderBird 115.7.0 and Windows 10.

Most of my emails are going to trash, once in a while I may get one in my inbox, not very often. I now just go to trash for my emails, I am not very tech good but have tried and my son also tried, but we couldn't fix it, we probably may it worse. So I am coping by using trash as my inbox. I know this is not a permanent solution and would very much like to know what I did wrong and get it fixed so I won;t screw it up again. Thank you for your time.

After updating to TB 115.5.2, we keep getting the following error message when we try to send or forward an email: Sending of the message failed. An error occurred while sending mail. The server is not responded. No such domain at this location. Please check message recipient "xxxxx@gmail.com" and try again. I get this error on all emails we try to send. We get this same error on my spouse's computer also that we use Thunderbird with. I have already checked settings with my ISP and the POP settings are correct. We can use other mail servers such as outlook.com and gmail.com using Thunderbird. ISP is cis broadband. have checked firewall, have uninstalled Thunderbird and re-installed without solution to problem. ISP has checked port to make sure it is not blocked.

incoming emails do not seem to be effected.

I had emptied my spam and junk folders but unfortunately I had marked up one email address as such which I need to undue, but I can't find where the list is. Where do I find it please?
