I had Thunderbird on my Windows 10 computer. I bought a new Windows 11 computer and downloaded Thunderbird. When I try to set up my email account, I provide my full name (not my Thunderbird user name) and email address. The next screen has the message "Configuration found in Mozilla ISPDB ". I clicked on IMAP and hit continue. The next screen I type in my password for my Spectrum mail account. I have confirmed that the password works went I log onto the Spectrum website. The next screen has the Authentication error "Unable to log in at server. Probably wrong configuration, username or password.". I've also tried using my Thunderbird user name and Password instead of my full name and Spectrum password with the same results. I know my Thunderbird user name is correct but I can't be 100% sure that my Thunderbird password is correct.

I'm not sure if this matters but my email has the has the extension ----@socal.rr.com. This was assigned to me by my original email provider, which was Time Warner Cable. Spectrum bought Time Warner Cable a few years ago and I think Spectrum uses a different extension.

What is the best way in TB of organising the storage of email messages on my local storage device:

• Many folders/subfolders, each containing a limited number of messages?
• Few / One Archive folder containing all messages, each message tagged with one or more tags for easy search/retrieval?

I would prefer the latter, but I am unsure if there are any limitations to how many messages that can be stored in one folder i TB.

• Are there any practical limitations regarding the no. of messages in one folder?

I recently got a notification that a Thunderbird update was available, so the update was downloaded and installed.

Next I went to my inbox to tidy it up, by deleting some items and archiving some that I wanted to keep. On looking at the 2026 archive none of the items where found.

Why has this happened and is there any FIX ?

I am not able to receive or send emails using my wifi, but can using data (same provider). I have queried this with my email host and wifi provider and both have said there is no issue on their end that would block these actions. The email host suggested I change port 465 to 587 for outgoing to see if that made a difference. It did not.

This issue is occurring on the web platform as well as the android app.

The error message in account setting is: an error occurred connecting to gsyd1001.siteground.net:993."

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.

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

Hi

Just checking when ThunderMail and Pro will be available? I'm in need of email services for my small business and just don't want to subscribe to Google. I love Thunderbird, glad it survived so many transformations over decades and would like my subscription contribute to further development.

Can you, please provide me with at least estimated timeline?

Thank you S

Prelude:

1. I have several email addresses in Thunderbird.

ISSUE:

1. One address, the first on the list, Draft folder shows "1"
2. View email Shows "No message found"

QUESTION: I like to keep a tidy Thunderbird - how might I fix this issue?

Thanks for the read, ~r BTW - this seems to be the last of the gremlins since my migrating - - Thunderbird - - Yea! :)

After I migrated everything to a different computer, 'Local folders' no longer appears in the side bar, so I cannot archive messages locally.

Can some kind person please help me to reinstate it?

For the second time today, I lost the entire body of a rather detailed email I was composing for two different glitches. When I started to reconstruct the first I was hitting cntl-S frequently. I relaxed a little for the second and was about to save, but I got a message about the attachment from my drive that I was forwarding, and the entire body was again lost.

From the posts I've read, it appears I'm not alone. Unclear what triggers the saving of a draft, but is there a way to increase the frequency? Between the two I lost today, I wasted over an hour and lost some of the original thinking.

I searched the setting help, but didn't find anything.

Thanks! Bob

Witam serdecznie mam problem z kontem darekkowalski@konto.pl mam zajęte 97% i nie mogę tego zmiejszyć już odistalowałem pocztę wyczyściłem i nadal to jest to informacji przesyła skany mojego problemu proszę o pomoc jak to zrobić dziękuję Dariusz Kowalski

I'm new to Thunderbird so can you explain what is the status of a Local Folder, please. Does it count against the email allowance? and How can I move emails from a Local Folder back to the main folders, please?

I wish the subject line in an email would be editable ala Office Outlook. I make frequent online orders and the acknowledgment emails often simply have a subject line such as, 'Thanks for your Order' 'Order delivered' 'We got your Order'. That tells me very little. If I could add something like, 'Best Buy - backup ups battery', 'eBay - head phones', 'Walmart - house wares' that would make life much simpler. --Don

Is there a bug in the code for v152? I need to connect to a ms office 365 email account with requires OAuth

The create new account process does not work, because it forces you to go through the whole (manual) process which then fails because you cannot select the Oauth option from Authentication method dropdown box - because its not there !.

This URL with the process to add OAuth: https://www.bing.com/search?pglt=419&q=setting+OAuth+in+thunderbird&cvid=22ed20c67b3843d58ddbc136bed2f174&gs_lcrp=EgRlZGdlKgYIABBFGDkyBggAEEUYOTIGCAEQABhAMgYIAhAAGEAyBggDEAAYQNIBCTExMjgyajBqN6gCCLACAQ&FORM=ANNTA1&PC=ASTS

fails at Step 2 because it does not let you complete to then go to Step 3 - because the account is never created !

How do I fix this ? thanks

PRELUDE: I have Thunderbird (TB) Version 152.0.1 (64-bit)

I have 45+ email addresses, some at various different domains, 8 (was 10 yesterday) Email accounts with Shaw that was taken over by Rogers. It's been a nightmare. I now have TB working almost as it should, and am use to but, one account has issue.

I tried to format this so it's easy to follow, but more formatting is not available so please see the pictures attached. Pics are self explanatory, but in case, pic 1 shows 3 accounts. The address with issues is the middle address (fake-two (faketwo@there.xy). The other 2, fake-one and fake-three have all their folders.

ANSWERS to possible questions: I used a outside mail to send/receive to/from fake-two. It receives and sends Email.

I have Juno Email Accounts ; What are the Settings ? ... Incoming, Ports, Outgoing, Ports

Mozilla Thunderbird Will Not Install on Win10 Machines ... The Auto Settings Algorithm has issues.

Email Address : [edited] @Juno.com - TextMail : [edited]

/edited email and phone# from public community support forum

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

Dear community,

I'm planning to change my email provider and during the transition period I need to have the old and new accounts running concurrently. The help article states:

".....you can create additional profiles, each with their own set of account configurations, messages, etc. (Note, each profile can access multiple email accounts''.) .

but I can't see how this would work. If anyone can explain in simple terms how to achieve this, or point me to the relevant information I should be most grateful.
