Thunderbird Community Forum

Changed our broadband provider on Friday from PlusNet to EE and, since then, have been unable to reply to emails on my Thunderbird Mozilla account. I am still receiving them but when I attempt to reply I get the message:

"Sending of the message failed.

An error occurred while sending mail. The mail server responded: <X@dolhun.co.uk> recipient rejected - relay denied. Please check the message recipient "X@dolhun.co.uk" and try again."

Can anyone offer any help please? I am not very computer savvy unfortunately 'Regarding the question below which I have answered 149.0, to be honest I don't know which Thunderbird version I have but I had to fill in something!!

PRELUDE: I have several email accounts. All accounts display properly, except one. Yes, this is similar to my question about bottom of the far left [of emails] list of emails - but this is different.

On the far left of Thunderbird is a list of all my email accounts with "Inbox" etcetera. Each email account shows it's Inbox/Sent/Deleted/ except for 1 account. The problem email account only shows it's Title and Inbox northing else. Yes, I tested it and sent emails to it, and used the problem email account to send, create a draft, and they don't show..

The image explains it.

Thanks for reading this ~r

Hello, I use Thunderbird to manage several email accounts, one on them is not active anymore but I still want to be able to access the emails stored in my thunderbird directory tree, so I keep it active. And the fact is that every day this account tries to access a remote server that does not exists anymore to retrieve email that can not be retrieve, and every day I am asked for a password that cannot work. But the fact is that I did deactivate all options to read remote emails for this account, so that behavior is odd and I am not able to find a way around it. Any idea what to do not to be bother anymore ?

Thanks in advance for your help :-)

This is a new thing. The 2 devices (laptop and Kindle) have always synced my Outlook emails. New today. Can be fixed I'm sure but don't know where to start. Thanks!

Hello,

Does anybody knows why or how this happened? Thunderbird has worked just fine since the May 1. My internet connection works well. Has anybody had this problem before?

Thanks

When I try to access my e-mails I am getting message." Login to server pop.tiscali.co.uk with username [redacted]@tiscali.co.uk failed." Nothing I do helps

I don't wish to use the calendar that comes with Thunderbird, but instead continuing with my Macintosh iCal.

1) How do I switch off the Thunderbird calendar function? 2) How do I get the calendar invitations sent to me as an ICS file attachments, that I can open in Mac iCal. Just like in Airmail and in Microsoft Outlook.

Mozilla suddenly says "The certificate for mobile.charter.net does not come from a trusted source." It will not let me get my emails. Is this a problem with Thunderbird or Charter (Spectrum) I am able to receive email on my I Phone. I do not know which Thunderbird version and can't find it using your instructions. Help please

I have a number of pop3 accounts with the same mail host, but suddenly one of them gives me the message "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

I use Thunderbird on two Windows machines, and the problem is on both, so it is something in the interaction with the server, however, there is no problem accessing the mail via webmail directly on the server.

I have tried to change password on the account, but the problem did not go away. In fact, I got the box to tell me that the old password did no longer work, so I know that the problem pops up after log in to the account. Before the error message appears, the message "downloading 208 messages" (or something similar) briefly appears.

Is there a way to find out exactly what fails?

I'm using thunderbird 149.0.1. I'm trying to add a microsoft exchange account (@outlook.com). Using the account hub, after I entered the full name and email address and did the two-factor authorization, I'm stuck on the second screen (see attached). According to the instruction , I should not enter my account password in the first dialog box. However this is not possible since the password field is required. If I enter my account password in the password field, and leave the "Your login" part blank (or fill it with my email address), the window would complain "Exchange auth error" after I clicked continue. If I put a random string in the "Your login" field, clicking continue would lead me to a microsoft signin dialog, and if I sign in with my credential and password, the same "Exchange auth error" would still appear after I finished all the steps in the microsoft popup.

Hello,

This would have been a reply to https://support.mozilla.org/en-US/questions/1390397?utm_source=chatgpt.com which is one of the top google results for "Thunderbird make font fixed length addon"

Some html text is hard to read, I would like a button, to make it all one more readable font. (font override toggle button to variable lenth font) and a button to make it a fixed length font (font override toggle button to fixed lenth font) Maybe a button to also strip formatting like bold/italic/coloring etc..

The solution

Preferences > General > Language & Appearance > Fonts & Colors > Default font > Advanced > Font Control > Use fixed width font for plain text

Which is too deep into the setting to casually flip for one message and then bring back to normal. I don't want this forever, just when there's one hard to read email.

Running 149.0.2 on Mac. Reorganized IMAP folders in Roundcube webmail. Thunderbird still shows old structure. Deleted folderCache.json, no change. No Subscribe option in right-click menu. Many thanks!

I upgraded my Fedora nad I think that Thunderbird 149 came with that upgrade. I cannot send mails. Ctrl+enter has no reaction. Downgraded to 148 and everyhing is fine. |<
