Thunderbird-Hilfeforum

I am running 4 email addresses (3 hotmail.com and 1 live.com) on TB 102.15.1 (64 bit) - Windows 10. About a month ago I upgraded TB was unable to send anything no matter what Server settings I used - tried every combination - so I downgraded back to Version 102 and everything went back to normal. About a week ago, one of my hotmail accounts started giving me a "fail to log in" message. The other accounts work fine. The "fail to log in" will go from 2 or 3 times to 15 to 20 times in about an hour or so but every time, sooner or later will work and then it will be fine for a few hours and then start again. I have had these accounts running on TB for well over 10 years with no problem and I have not changed anything in the Server settings or anywhere else. The account I am having the issue with has been running on TB since TB started with no problems until now. I assume that TB may be having some issues with the Outlook platform but I have not changed anything there either and I have no problem logging into hotmail.com directly. I have spent many hours combing the internet for hints to no avail - everything I have tried has either had no effect or screwed things up so I had to back track to where I started. Any ideas???

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

Hi,

I have just setup a new Office 365 account in Thunderbird and when I try to send an Email from the account, I get the attached error message.

When I click on "Enter New Password", the window goes away for a moment and then pops up again. There is no chance for me to put in a new password.

I know that I need to use an app password when not using Outlook which I have generated in my Microsoft account settings.

I have tried to go to "Settings -> Privacy & Security -> Saved Passwords" and have deleted all Microsoft related saved passwords. When I access my Email account again, I get prompted via the web login of Microsoft (i.e. different from the attached error message) and the app password I generated doesn't work, only the general password for my account works.

I have restarted Thunderbird and updated to the latest version, but it made no difference. I have gotten it to work on another computer, but on my mac mini, it doesn't seem to work.

Before I remove the account completely and add it again, is there any way I can fix this as I don't want to download all the messages again?

Is this a known bug in Thunderbird?

If any developer is reading this, In order to reproduce, you would have to follow these steps:

- Setup a Office365 account using the regular password used to login to the O365 website. - When sending the first email, enter the same regular password -> the first time, the dialog to enter the will show up, but it will fail, because the app password wasn't used - Then try to send again, click on "Enter new password" -> no dialog to enter new password is coming up.

I am using Thunderbird 115.10.1 on MacOSX Sonoma 14.1.1

The settings I have used are: server name: outlook.office365.com port: 587 username: my full email address Auth Method: OAuth2 Security: STARTTLS

Thank you for reading this. Looking forward to a reply.

Sometimes a mail comes in, a notification sound is played - but no notification pops up (Thunderbird notification).

How come?

The mail comes in normally and arrives in the inbox - it has no filter settings.

Thanks!

A few months ago

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

It is supposed that all emails (received & sent) are saved locally in Thunderbrid. I moved my hosting account from one provider to the other provider, I setup same email address as i had with the previous provider and also using in the Thunderbrid. I could still see all the emails but Thunderbird asked me for a new password. Things were ok up to this point but when i entered the new password, all of a sudden all the emails of that account disappeared. Surprisingly when i try to search something using search toolbox, Thunderbird shows me result from all the emails that are disappeared.

I believe emails are still there but disappeared due to some glitch & that need to be fixed in the code. Can anyone please provide me a work around or development can fix this bug & release a new version ?

Thanks Farhan

My Yahoo IMAP account in Thunderbird no longer has any email showing in the Sent folder. There's plenty of mail in Yahoo Sent mail in the browser, but it's not finding its way into Thunderbird. I tried the Repair option, but I just get a typical message that I often see for Yahoo:

"The current operation on 'Inbox' did not succeed. The mail server for account Yahoo responded: [SERVERBUG] UID FETCH Server error - Please try again later."

The Yahoo account shows Sent mail in my iPhone. The Thunderbird Sent folder was seeing messages as recently as last week, so this seems to be a new problem, and I don't know if it's something that I did wrong by mistake. Thanks for any help.

Hello Thunderbird users!

Today my father lost all the sub folders below the folder Archives. Doe anybody know how to get them back?

I tried the following:

• Clicked on Folder Modes -> All Folders
• Tried the solution mentioned here: http://kb.mozillazine.org/Local_Folders

The strange thing is I also don't see any .sbd or .msf files, with one of the names he mentions, under the directory Mail (in the profile directory). How can they suddenly disappear or be deleted?

If someone knows how to get the folders (with the e-mails) back, that would be very much appreciated!

I renamed a folder and now the folder is not showing. As the folders contains few emails and I want to those back, tried restarting the thunderbird many times. Let me know if faced the same before and found a solution for it.

Opened TB 115.11.0 (64 bit) this am A compact procedure started up. I am now left with a message whose subject is quite different from the content The next message has just come through - apparently no problem, but the original error remains. See screenshot. Not sure what to do next!

Hi I decided to donate so I could get rid of the automatic start of my browser showing the request for donation screen whenever I open Thunderbird. Even though I received the confirmation that I successfully donated, I still get the annoying request for donation. How do I stop the auto load of the browser?

I just signed onto Mozilla to do some emails and my history email and files no longer appear. My address books are there and ok.

How do I get my history emails back?

Thanx for your help and suggestions

For some time now TB has been opening with a blank screen. I've located web advice which reads in part "Usually if you go to "Tools - Account Settings etc, TB will start in the Inbox folder" but that doesn't help because those are already my settings. I'm convinced that I have changed something because TB always used to open in the Inbox folder. Solution would be appreciated.

First post. I was trying to target a Thunderbird forum but I get vectored to Mozilla which seems to be more focused on Firefox. Sorry if I'm in the wrong place.

First, it was my impression that a global Inbox could be POP accts only. But my global Inbox has a POP acct and an IMAP account. I'm not sure but this might have happened when I converted one of my POP accts to IMAP. Am I wrong about this theory? Going forward, I'm going to refer to this IMAP acct as the "bad" one.

As a result, my bad IMAP acct that appears in the global Inbox has no Inbox of its own under its account. What I'm looking to do is get the bad IMAP Inbox out of the global Inbox and back into its account in my sidebar.

There's nothing wrong with my e-mail but I want to keep it that way. I have another IMAP account (aka "good") and as a result of my situation, I have to look at the bad Inbox and the good Inbox of the two IMAP accounts in different ways in the interface and it annoys me.

I've looked at the account settings. The good IMAP acct has the personal namespace "INBOX." whereas the bad IMAP acct has the personal namespace "". I've tried changing the bad personal namespace to "INBOX." as well but I also have "allow server to override these namespaces" and it won't stick. I don't understand IMAP well enough to be confident about making more changes without getting advice.

Hope this isn't too confusing.

I have moved Thunderbird from the new Microsoft Outlook and I am very happy with Thunderbird except for one thing.When sending an email I often get the error message:

"your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent-jemsym@aussiebb.com.au."

How can I correct this? I have checked the outgoing SMTP details and have changed a couple of things with AussieBroadband. the problem remains. Can you help?

Hello,

Please check the attached picture. My "Blogs & News Feeds" contains an empty "All jobs upwork.com" folder and I can't figure out how to remove it.

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?

Error message 'side by side configuration error'. I've been advised to re-install Thunderbird but not sure if I will lose my many thousands of emails and my address books etc.
