I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

I've been using Thunderbird for about two months now and I just realized that Thunderbird (150.0.1) seems to be unable (or unwilling) to use some of the fonts that are on the computer (Windows 10, plenty of RAM and disk space).

Let me explain that I don't send a lot of emails, and most of the ones I do send are just a few lines so I had not had any reason to bother with the font -- the default font was fine -- until today...

Today my experience with fonts in Thunderbird was extremely disappointing. It started when I was composing an email and I copied/pasted some text from a web page into the email. Rather than treating the pasted text as simply text to have in the default font, Thunderbird put it in some strange font and size. This might have been Thunderbird's attempt to use the font from the website but neither the font nor the size resembled the text that I had copied/pasted. That was when I noticed that Thunderbird does not let you choose the actual size but only offers the choice to make text larger or smaller. Making the text smaller was sufficient for that particular time.

As I finished the email, I tried to sign my usual signature. Thunderbird lets you choose the font but once I had chosen the font that I routinely use for my signature, I discovered that Thunderbird totally ignores the choice that it just let you make. Instead of displaying the signature in the chosen font, it displayed my signature in a plain sanserif font.

I could live with a limited choice of fonts -- I have used another program where the only choices were serif and sanserif -- but I cannot understand why Thunderbird would offer a font choice menu that includes all my installed fonts when it actually only honors three choices. The only fonts reliably used seem to be some generic sanserif font that Tunderbird calls Helvetica/Ariel, a generic serif font that it calls Times and another serif font it calls Courier.

The dropdown menu lets me choose any of the fonts I have installed, some of them display properly while composing the email, others don't. If I send the email to another of my email addresses, Thunderbird displays the text the same way -- some fonts are correct and some fonts get replaced with one of Thunderbird's generic fonts.

I'd really like to have all my fonts available -- but that doesn't seem to be possible with Thunderbird so I guess I need to figure out which fonts Thunderbird is willing to use.

Emails coming into my email account with Telstra are not arriving, BUT I can send... Telstra support today says it is a Mozilla problem ? Please unlock or repaire???

I created a new email account but during the setup the account got added with incomplete login details.I am trying to delete this account so I can recreate the same, but it cannot be deleted. I tried running as administrator as suggested on google but this also did not succeed. Now I realize that the new account which I was trying to create has merged with my default account and corrupted this account as well. Now I am unable to delete both these accounts.

I am stuck badly as my default account is not allowing me to send emails. Please help me.

Hi, Why can't I see or find the calendar in Thunderbird anymore? Is it no longer appearing next to "New Message" like it always did? I have a lot of recurring events on it from the many years I've been using it, and I need to add more events. Please advise. Thanks

whilst all incoming emails are visible, many do not display their message header in the Inbox List. such as the one captured with a screen shot. Several have displayed in this manner over the last few days as can be seen.

all emails that I send have no text appears, but 1 attachment shows. Click on the attachment and the text appears. I wanted the text showed in the email not attachment.

SIMPLIFY THUNDERBIRD IT IS EXCESSIVLY COMPLEX. I CANNOT EVEN SEE HOW TO MOVE MESSAGES FROM THE INBOX TO THE RELEVANT FOLDER IN MY LIST. I PERSONALLY BELIEVE FIREFOX AND THUNDERBIRD ARE OVERCOMPLEX AND NEED SIMPLIFIED. SIMPLES. WHY CANT I COPY AND PASTE THE VERSION NUMBER. BLOODY ARESHOLES . AS I SAID IT IS BLOODY OVERCOMPLEX. AT THIS POINT I AM CONSIDERING GIVING UP ON WHAT IS CLEARLY AN OVERCOMPLEX PIECE OF SOFTWARE THAT REALLY DOESN'T LOOK GOOD EITHER AND THERE IS NO OFFICIAL SUPPORT SO WILL HAVE TO LOOK FOR AN ALTERNATIVE. COMPLETE WASTE OF SPACE TOO MANY COOKS SPOIL THE BROTH COMES TO MIND THIS IS WHAT WE HAVE HERE

Hello,

After moving my Thunderbird profile to a new computer none of my accounts can authenticate. I followed the instructions here: Move Thunderbird data to a new computer, using "An alternative method for manual transfer between Windows 10 and Windows 11 computers." What explains the response in the attached image, "Something went wrong," and how can I fix it? Happens when I click "Next", the first step to log it.

I have a related problem with other accounts set up in the profile. This one is using Oauth2. I tried switching to password, and hand a similar problem. I tested the connection to the server in Settings for the account and it was successful. Same for the others. They all authenticate successfully on my old computer.

Thanks...

I have set up 4 email accounts in Thunderbird. I tried today to set up another email account with the same domain. selected the New Account Button (email only); then pop up screen to add name of account user and users email address. next menu, TB was successful finding the server but a small yellow flag says "unknown hostname" but lists the 3rd party host, that there is SSL/TSL security and the user name matches the new account information just entered. Incoming settings looked correct. The next screen is Choose email account type and it was auto populated by TB and all info is correct. Next, enter password (for new account?) and TB fails to create a new account. Says Authentication error unable to log in at server. Tried doing the manual config. Outgoing server protocol shows SMPT when it should be IMAP (correct?) but the field is un-selectable. So results are same, Unable to log in to server.

the manual config screen has a host name field and it is autofilled with my company's name.domain but it is misspelled! Tried to edit but no success. I really need to get this new account up quick! So asking for any help available.

Starting yesterday for no apparent reason TB has been unable to connect to my email accounts. (IMAP or POP). These include Roadrunner, Gmail and Outlook.

Any Ideas? James

I am in the midst of the long process of moving most (not all!) of my gmail from the gmail server to TBird, using filters as discussed in this thread.

I've started by first using filters on less important emails (ie so that no true disaster occurs if something goes horribly wrong). As I do so, I have questions!

For example, let's say I use a filter to: copy all the emails from @someone.org to a local folder then delete those emails (from the server)

What happens if one of those emails happens to be within a thread, including emails from people who don't match the filter (ie are not @someone.org). Have I broken the thread forever, ie, has something gone horribly wrong? If so, how do I prevent this behavior/have the entire thread move along with the targeted value? If not, I don't see how I can move email without breaking threads, which is a bit of a problem.

(Also - whoops, I see I should update, but the question remains.)

Sending of the message failed. An error occurred while sending mail. The mail server responded: <anonymous@[10.0.0.31]>: Sender address rejected: not owned by user a1.914306843. Please check the message recipient "christine.krieger@a1.net" and try again.

why do I get this on new download

My correspondents keep getting shuffled and applied to the wrong subject line in the inbox. It was suggested that I right-click on the folder, select "properties" and then "repair." That clears it up, but only for a matter of hours. Plus, any emails that I have open get closed and then I have to find them again.

One person who suggested that I right-click the folder and repair it said if that didn't work, there was a more technical fix. I need it!

Help!

I have two Gmail accounts and one school account that uses Office 365. In the left panel where the inbox, drafts, etc. are, the Gmail accounts are listed in blue but the school account is listed in white. I can't see any reason for this difference in the accounts' settings. What does the difference indicate?

1. 1

Recently I have been unable to use my Verizon.net email account on Thunderbird. An AOL pop-up requests I sign in with my jsturni@verizon.net userid, but returns "Oops, something went wrong." I still can access the account on the web, so I know my password is OK.

1. 2

In addition, I can not manage to set up an additional js_consulting@verizon.net account. I tried auto setup as well as manual. I also can access this account on the web, so I know my password is OK.

(They both had been functioning until a few months ago)

Suggestions appreciated. Thank you.

When I try to print a PDF attachment it comes out as a blank sheet. This used to work OK. The print preview is fine. I have altered the settings to open PDFs in acrobat as a workaround. Any help appreciated.
