Форум поддержки Thunderbird

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

Hi, I am trying to login to my emails and after entering my password the following message comes up message comes up. 'Login to server mail.optusnet.com.au with username dianne.hill failed' Can you please help me?

I have reviewed the previous forums on what changes to make to the outgoing stmp for outlook and have implemented them however, I am still unable to send emails. Please see attached for the edit smtp settings I am using. According to the forums these are the correct settings. The only difference is that I don't seem to have the ability to set authentication method to login as that is not an option for me.

What am I missing?

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX. Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

Support needs to take their head out of the sand! With the latest release of Thunderbird for iOS it does not work when trying to type a message. The default is "preformat" and trying to change it to paragraph or other does not work. Older version works on my MacBook Pro (2011). My MacBook Air, Thunderbird writing message does not work. Glad I did not contribute money! Oh well must be a way to get folks to purchase Office 365, Outlook?

I need to set up several gmail accounts in Thunderbird. The accounts exist; I can see email by going to gmail's webmail for them. I'm running Thunderbird 115.10.1 on Windows 11.

I choose Tools > Account Settings > Add Mail Account then provide the name, email address, password, then TB validates the credentials with gmail's systems. I get a green light message saying that gmail found the entries. I then provide the appropriate POP3 server name and port address and the appropriate SMTP server name and port address and confirm security settings - all of which were verified and carefully edited when entered. TB then sends the information to google and after an very long delay returns a message saying the attempt failed, probably due to incorrect password or settings. All of the information and settings - including the password which was copied and pasted AND the same one used to log in to gmail webmail - are correct.

Obviously, I'm doing something wrong but don't know what. The error message is so generic as to be unhelpful.

Can anyone help me discover the problem?

Dzień dobry, Chciałbym uzyskać pomoc z odblokowaniem możliwości wysyłania wiadomości, mianowicie prowadzę restauracje i wysyłałem duza liczbę wiadomości z ofertą gastronomiczna i nagle pojawił się problem.

I remember when you could select a range of messages and delete the lot quickly. This is how I maintain my email. For a while now, and still, it takes a bit to sort messages, normally for me sort is by "Correspondent". Then when I select a range and hit delete, I may as well go do something else. Thunderbird goes unresponsive for the long duration. It is a major problem.

I am still using Win10 Pro, system disk is an SSD (1 TB) and the data disk is a normal HD (4 TB). 16 GB RAM, a Lenovo tower. It is not running out of memory, the drive isn't over utilized either. A 15 message delete is slow, try over 100 messages!

All other programs run fine, it is used in electronics design mostly. This issue popped up a while ago and I kept hoping it would be fixed. It hasn't yet. The OS is kept up to date, no other changes. I do compact folders regularly, so indexes should be optimized.

There is an email app provided by xiaomi on my phone.What in the email sent by this app contains a special format of `Date` fields.It looks like that: `Date: Thu, 2 May 2024 05:55:12 UTC` It doesn't look like others' `Date: Thu, 2 May 2024 06:05:15 +0000` or `Date: Thu, 2 May 2024 10:35:14 +0800 (CST)`

but it is still conforming to standards (or is it only parsable by the JavaScript Date method?)

After I modified windows time zone and restarted thunderbird. all emails changed time so this is not a time zone problem.

But this email shown two different times in the preview and detailed pages at this moment.

So can anyone tell me if this is a bug? Thank you.

When I start T'bird in normal mode, I get what you see in picture #1. Notice the custom menu bar at the top. I can still receive emails into the Inbox (but can't see or access them), and I can write an email, access the Address Book, Calendar, etc.

When I then start in Safe mode, with Shift key down, I get what you see in Picture #2. Notice that the custom menu bar at the top is gone. I have to recreate it every time I shut down and restart T'bird. That is unacceptable.

Please advise what I should do to correct this situation. If I can't, then I'm through with Thunderbird (after some 15+ years).

Many thanks, Robert Hawkins

My Local Folders has become corrupted after restoring from a backup. I can't delete or move subfolders, and can only delete messages by holding down the shift key. Is there a way of repairing this? Thanks.

Several days ago, my comcast email said it couldn't connect, and after trying a couple other things, I removed the account and tried to add it back on. When I try to add it as an IMAP account, it pulls up a window that loads for a minute then says "Unable to connect. An error occurred during a connection to localhost." On the thunderbird window where I entered my password, it says "Unable to log in at server. Probably wrong configuration, username, or password." I logged in on a browser, so I know the username and password are correct. I tried adding it as a POP account, and that worked fine, but I need it as IMAP.

Hi, I have Windows 11, Intel processor, 64 Gb RAM, TBytes of SD storage. Lately I have been experiencing issues displaying email with attachments. It is intermittent, but occurs when I display an email with one or more attachments such as PDFs. I have a preview window open to the right of my mail list. If I click on the item in the list I see a properly formatted email in the preview window .. for a few seconds. Without me touching anything, the mail converts to HTML and the attachment is gone. Redisplaying the item goes right to HTML. Further, the HTML has nothing to do with the original message. If I go to my mail server the original item might still be there, but it might be gone. I have not seen a pattern to determine why some are gone. I need to solve this. I don't see this problem described in previous posts.

Attachments: tbird_before.jpg - preview email with attachment (personal data obscured) a few seconds later it switches to tbird_after.jpg and I cannot get the email back.

My TB repeatedly downloading all the emails in my Inbox, it is slowing down TB and can't access and reply to current email due to it. Is there any solution to it without losing my data?

Apparently the latest Thunderbird update is causing our Windows 11 print spooler to stop. I've seen this problem talked about elsewhere but have not seen a solution. The spooler has to be restarted, otherwise no app/program will print, since only Print to PDF is then available. This is making Thunderbird almost useless to us. Help.

It all started about 3 days ago. I was having problems accessing my att.net email account on both my iMac running Thunderbird 115.10.1 and on my iPhone running iOS 17.4.1. I changed login password and was able to get the mail on iPhone, but not on the computer running Thunderbird. I got the settings information for both POP3 and IMAP from att. I first tried to go into Thunderbird and was able to find the email protocol settings and they were correct for POP3, but still not retrieve email. The error message I last received is, "Sending of password for user ******@att.net did not succeed. Mail Server inbound.att.net responded:[SYS/TEMP] Server error - Please try again later.

Thunderbird Error Message (attached). Sending of the message failed. The message could not be sent because connecting to the Outgoing server (SMTP) cs15.uhcloud.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What is the phone number for support?

After clicking the Thunderbird to enter my email the whole system goes through connecte3d to uepat624@gmail.com then up comes a message from Thunderbird indicating "you may have too many cached connections use IMAP Advanced Settings to reduce cached connections" Then things continue on for probably 5 to 10 mins. sending login info, looking up IMAP, checking mail server capabilities, looking for folders, sending login, opening folder box, downloading

Eventually email inbox and messages come up. I can send, receive and send mass mailings but when you read a message and want to go back to the inbox you have to scroll all the little boxes at the top of the screen back to the one that says "inbox".

I need someone to remove the cached connections. Pat Blackburn
