Forum Thunderbird zajednice

My ISP has made a change for "third-party" accesses to its e-mail (which still works fine on its own website e-mail access page). I need to check my Username, Password, SSL, Protocol, Incoming & Outgoing Server Ports. BUT I don't see on my Thunderbird page where to find these: it's my preferred way to do e-mail! Where are they??

I have 6 email accounts linked to Thunderbird. I noticed today on one of the accounts, along with inbox, drafts, sent, etc., there is now a spam icon. I didn't change any settings or even look at that email account today. This is the only account with that icon and it won't allow me to delete it. All settings between all accounts are the same, just this dang spam fire icon that I can't delete

I am trying to add an Proton mail account to Thunderbird using the Proton Mail Bridge (PMB). In the PMB guide it is recommended to uncheck Account Hub in the Setting>General. The problem is that the Account Hub still pops up when trying to add a new mail account - it simply refuses to go away regardless of several restarts of both the computer and the mail client!

I have a new computer and I am loading my email accounts into TB. One of them loaded perfectly but the outlook account has been trouble. I have read several forum questions/answers and tried all of the suggestions with no help. I will attach a screen print of the page I get when prompted to enter password credentials. I cannot go further until I can get TB and Outlook to communicate so I need help. I don't want to use Outlook as an email server if possible.

Thunderbird 148+ on Windows 11 repeatedly prompts for the password when synchronizing an Exchange account (professional) configured with the native Exchange support (no add-on installed).

The account only offers “NTLM” or “Normal password” authentication methods. OAuth2 is not available in the account settings.

During synchronization, Thunderbird asks for the password separately for many folders. However, clicking “Retry” usually works immediately without changing the password, and manually re-entering the same password also works.

The issue then reappears for the next folder, causing continuous authentication prompts (I have many folders...).

Actions already tested:

• deleting saved passwords and tokens,
• deleting/renaming key4.db and logins.json,
• restarting Thunderbird,
• recreating the account.

The problem persists.

This looks like an authentication/session handling issue rather than an actual invalid password.

I have email accounts that are with Shaw (shaw.ca) which was bought by Rogers. I've had these accounts for years, and about a week ago the emails were not being downloaded and I could not send emails either. The email server is : Incoming - imap.shaw.ca, security type SSL, port 993

                   Outgoing - mail.shaw.ca, security type STARTTLS, port 587, with domain shaw.ca

I deleted Thunderbird and reinstalled it on my desktop computer that runs Windows 11, and attempted to add my Shaw email accounts using the above email server information, however received an error message that it could not connect to the server. I was however able to set up my Outlook and Hotmail accounts and could receive and send messages.

I also have Thunderbird on my laptop (Windows 11), and the Shaw email accounts were also unable to receive or send, although they were receiving and sending last week.

I contacted Shaw (Rogers) technical support and they said the Shaw webmail was operating because I could send and receive using Webmail, but that it must be an issue with Thunderbird. This did not make sense as I also installed Canary and Mailspring, and was unable to have my Shaw email accounts set up in those email programs with them being unable to connect to the Shaw email server. The tech rep said I would need to contact Thunderbird to have them confirm there was no problem on Thunderbird's side.

I also installed the Outlook email program and tried installing one of my Shaw email accounts using the Shaw server specs, and it installed the account and connected to the Shaw email server. I was able to send and receive emails from it. When I used the same Incoming and Outgoing specs in Thunderbird, Canary, and Mailspring, it would not connect to the Shaw email server.

Any suggestions as to what the problem might be and what might be done to correct it to allow my Shaw email accounts to be set up in Thunderbird would be much appreciated. Thanks.

keep getting connection to sever failed, wont load any emails or send messages, does not show any old emails that were saved, settings are all correct tried all fixes, nothing works ?

Hello,

I can't receive any of my e-mails. I can send e-mails out now. Plus I can put in my password to log into my e-mail.  This has been a headache for me, I have been with Thunder Bird for years.

I also get a boxes that says : Unable to write the email to the mailbox. It says to make sure the file system allows me to write privileges, and I have enough disk space to copy the mailbox. I have enough space on my computer system and all. Another box that says my e-mail is being processed. Please wait until processing is complete to get messages. I did e-mail you yesterday on these issues. As I said I can e-mail messages out now also log into my e-mail with my password. Thanks, Chris

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

When I try to send an email via Thunderbird using my email account it errors out with a smpt error. I went in and deleted all the passwords (like it said online) to force a screen to pop up. Then I closed Thunderbird and restarted it with no success.

To whom it concerns, It just happened yesterday June 11,2026. I put in my password to my e-mail to open it and it stated that my e-mail account is being processed. Said to wait until processing is complete to get messages. I have never had this issue, I been with Thunder Bird e-mail for years. It isn't even showing my e-mails that I had in my inbox on my e-mail. If you can please help, I need my e-mail up and going. Thank you, Chris Note, it also said that Thunder Bird had crashed in a box, they wanted to know what page I was on. I am not understanding this.

All folders are shown ticked but they do not appear. I can view one folder at a time with Go>Folder>my account>Inbox(say).

Using IMAP. Firefox 151.0.4 I don't know what I could have done to cause this.

I think I've tried everything to figure out why Thunderbird will not send emails.

Yes there was an update the last week of May to version 140.11.1esr (64-bit).

Yes the incoming and outgoing mail server info gibes with my ISP (Shaw) - added pix

Yes have done the necessary adjustments to Windows Defender and Firewall.

Yes I have increased mail.news.tcptimeout because occasionally have received message that "Outgoing server

• SMTP" mail.shaw.ca timed out. Try again. Yes I have indeed tried again.

Yes I have called Shaw and they will not offer any suggestions because TB is a third-party.

What's left to try? A version reversion? Thunderbird has been so stable for so long. I even considered Betterbird but it uses the same profile so............

Thanks.

I have a large number of email accounts configured in Thunderbird, roughly 20 or more.

Occasionally, one of the accounts needs to re-authenticate or re-enter its password. When that happens, Thunderbird opens a password/authentication dialog, but the dialog does not clearly tell me which configured email account triggered it.

With only one or two accounts this might not be a serious issue, but with many accounts it becomes very difficult to know which account needs attention. I may see a login prompt, but I do not know whether it belongs to a reg@r...p.com or work@r...p.com, or jobs@r...p.com, or hello@r...p.com, and so on.

I get it, outgoing SMTP servers can be shared or associated with multiple identities/accounts. In my setup though, each outgoing account is effectively one-to-one, and I still have no practical way to tell which email address the login prompt is for.

Even when an outgoing server is shared by more than one account, it would still help if the prompt showed the related a list of the accounts/identities connected to that outgoing server.
