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.

Unified Folders in Thunderbird 115 for mac no longer works. Useless! Computer Tech specialist here and have been using Thunderbird for ages. With this latest version, the inbox, sent, etc etc etc no longer display as unified. The Unified Folders category when ON shows as its own item in the left column with a single empty inbox! Scrolling up and down to each account for each subfolder is a waste of time!!! Hope you fix this ASAP!!!!! Unified folders works fine in 10.12.13 but I cannot got back to that due to your system.

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?

Hello

Please can you urgently help with this issue.

We cant seem to access our Thunderbird email today. !

message : - "Server outlook.office365.com has disconnected. The server may have gone down or there may be a network problem"

Please advise ?

Many thanks Stavros Kosta

Hello! I accidentally hit 'K' with a thread selected, and so got a message at the bottom of the screen saying that replies to the thread will not be shown. This is the same situation as in the now-archived question [[Accidentally pressed "K" on an email - can no longer find it|https://support.mozilla.org/bm/questions/1380096]].

I'm now writing because I *was* able to select the option to display ignored threads described in the reply to the question above – so that I can, at least, now see the thread that I accidentally ignored without meaning to. But I'd like to actually fix the problem and un-ignore it.

I've read the support article on Ignoring Threads, but what that article describes – namely applying 'Ignore' to the same thread so that it toggles off to unignore the thread – isn't working. I also tried quitting Thunderbird entirely after doing that and then reopening it, but I can still only see the thread if 'view' is set to still display ignored threads; when I remove that view instruction, the thread disappears again.

Does anyone know if there's something else I should try? Or is this maybe a bug in Thunderbird that needs to be fixed? Thanks so much in advance!

The spell checker is constantly using English (USA) and not English (UK). No matter what I set it to it reverts. I suspect every time there is an update it does this and it is extremely annoying for anyone living this side of the pond (In the UK).

PLEASE can we have English (UK) by default. I notice when you add it to the list of languages in settings the USA version cannot be deleted.

I changed the email login for my primary account, thinking thunderbird would still show the years of saved messages in folders for the original account. They have gone away, but WHERE TO?

Hi! I have a lot of IMAP mail account and want to store all relevant mails in an lokal account stored on an local folder. So I created an new local account and selected in the account settings at the option Message Store Type "File per folder (mbox) to store each folder in an separate folder an the local file system.

The Account Name: RS_Mailablage_Zentral Local Directory .....\RS-Mailablage_Zentral

Now I want to move/copy some mails from the IMAP-account to the new local account in an new created folder. But it doesn´t work either by drag & drop nor by using the the option "Move to" in the Message-menu. It doesn´t work in the troubleshoot mode.

In the local directory I found all the created folders from TB as directory foldername, as directory foldername.sbd and as file foldername.msf. You can find some screenshots at the uploaded pictures.

Please can you help me to find a solution.

I use TB version 91.13.0 (64-bit) on Windows 10 Home version 21H2

Hello, have the latest version of Thunderbird (102.5.0.) in Windows 11 Pro. I'm using 6 IMAP accounts there.

I want to stop check mails automatically in one account, so I unchecked: - Check for new messages at startup - Check for new messages every 10 minutes - Allow immediate server notifications when new messages arrive

Problem is thunderbird still checks for new mails of that account and shows me notifications. What is bad please?

Tried to clean install of thunderbird, didn't help it. Thank you

Been using ThunderBird for many years to access my ATT email account ( [edited] @pacbell.net), but for the last three days it won't allow ThunderBird to access it and download emails. Have reloaded T-Bird, Changed passwords,, etc. but no good. Called ATT twice and they say since I can download from ATT sites it's T-Bird that's the problem....why after this many years???

Hi

Why does Thunderbird want all my personal information.......??

I'd be MORE THAN happy to make a donation to support you guys, but I am NOT happy about all the info I have to provide - and frankly I'm bot going to be bullied into giving info I don't want to. I donate to Wikipedia and they don't ask such intrusive questions - so why do you? You say that less than 2% of TB users donate - this PROBABLY the reason why they don't...!

And the fact that there is no direct link to ask somebody ask question about this subject, is really frustrating.

Thanks

I can't control the FONT SIZE of the incoming emails with the new version of T'bird. Hate it!! It's ugly. Looks crowded and, as I said I can't set it so the incoming fonts are a readable size. OR the font size in the individual mail boxes... This lack of control makes it next to useless for me. I'm in my 70s and really do need the larger font sizes.

Error message: "Sending of the message failed. The Outgoing server (SMTP) smtp.frontier.com does not support the selected authentication method. Please change the 'Authentication method' in 'Account Settings | Outgoing Server (SMTP)'." Can you help? Was on the phone with Frontier for an hour - they say incoming settings are correct (no problem receiving emails), as well as outgoing. We tested sending an outgoing message from their webmail server, which was successful. Thanks, dbleagle

I have just had an update to 112.0b1 (32-bit) but it looks completely different , I do not to uninstall this version and install old because I could lose all my folders

Any ideas how I change setting to look like the old version

When I receive a message in Thunderbird and click Reply, the Write window opens with some of the quoted text in the reply — that which has more than one line in a paragraph — containing overlapping lines. That overlap does not occur in the original received message.

Hello everyone, I just installed Thunderbird Beta (114.0b6 - 64 bit) out of curiosity.

When I import RSS Feed, all icons representing folders are gone unlike on Thunderbird Stable version.

Although Feed Subscription pop up window still show icon for each feed folder.

Is this normal on Thunderbird Beta?

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??
