I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

Recently I posted about this problem here: https://support.mozilla.org/en-US/questions/1580858 In sum, I was having problems both in downloading messages from the Spectrum server and also with sending messages. I've attached screenshots of the error messages.

Matt and David kindly posted some helpful responses. The problem then seemed to spontaneously solve itself and I breathed a sigh of relief. Then a few days later it re-appeared.

This time it's not quite as bad in that I'll get the error messages but then usually a few minutes later I can download the messages or send an email. But it's still a real problem.

I called Spectrum again and this time the rep was adamant that if I can still use the Spectrum webmail feature (and I can), then it's not a Spectrum issue.

Last time Matt asked about my antivirus. I use Windows Defender (and occasionally do a manual scan with Malwarebytes free version), so if I understood him right, I should be OK as far as antivirus interference.

Matt also suggested I set TB so that I download messages at startup and every 15 minutes. I was set to every 10 minutes so I changed it to 15.

Matt said for me to check the Activity Manager. I've attached a screenshot of what that showed a few minutes ago. But I should note that this was after an error message displayed but my email downloaded anyway.

Finally, Matt said I should check the Error Console (Control + Shift +J). I've attached a screenshot of that. He also said I should use the trash can to clear it, so I did. He then said to press Shift + F5 to attempt to get my messages. But on my laptop, F5 just dims the display so no dice on that. But I have a second laptop and F5 is "neutral" on that one so I tried it there. I didn't get any new error message.

However, one of the screwy things is that sometimes I get all my messages as normal, but only after the "Can't connect to the server" message displays. And that's what happened with my second laptop above.

I hope I've provided better info. this time. And I hope you gents can help me with this mess.

Thanks,

Andrew

My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.

Both domains are hosted with Bluehost. Exhaustive research has revealed the following:

• Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
• There is no subject line or content that could possibly be regarded as spam.
• MXToolbox indicates that the secondary domain is not on any blacklist.
• Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
• Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
• Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
• If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.

After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!

Thanks in advance, Don

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

Trying to set up you Thunderbird Im used to Outlook. The setup here is not the same and it won't connect. The "Manual Account Configuration" is not the same as the pictures here. Pic 1 = What your system picked Pic 2-3 = Is whats in my Outlook pick 4 = is what happens.

In your help: "Manual Account Configuration" These pictures look nothing like what I see in your setup I could use some help. Im uninstalling Microsoft 365 and replacing it with LibreOffice and Thunderbird.

Id rather donate than have 365 main Email is home@barrysplace.ca AS you can see, im using a email that i rarely use. dont want to mess with the main ones

Our e-mail became slow, and wont open new e-mails. This has been for at least a week. A few days ago our e-mail account stopped working cokmpletely, and when prompted to sign in, it does not recognize our password. I am contacting you via a different e-mail as we have no access to hrttohrt@charter.net, which has been our primary e-mail account in thunderbird for years. What can we do?

I'm new to the community and don't really know how things work, so maybe this is the wrong place for this. I had a seemingly catastrophic problem after updating yesterday. All of the emails sitting in my inbox disappeared, and were gone from the yahoo server as well. Long story short, I figured out what happened. In my filter rules I sometimes had a blank entry at the end of the list. Previously that had been ignored, but after the update it is now treated as a match. So the first filter that had a blank in it caused everything in my inbox to be moved to a certain folder in my Local Folders. Obviously, it would be legitimate to not allow blank entries in the filters, but once you've allowed it, you really shouldn't make a change. In the end the solution was simple, but it wasted a fair portion of my day figuring it out.

This just started today. I am seeing question marks between the sentences in my messages. I had this issue a number of years ago and do not remember the fix. I am running the latest version on my Windows 7 desktop. It is just the new messages not the older ones in file.

Anyone remember the fix?

Thanks

I have my gmail emails rerouted to my outlook email address and in past week my emails are not showing up in Thunderbird for a number of days after they are visable in my outlook program. Why? I have compared my Thunderbird settings with my partner and they are the same. Only difference is that my partner picks up her gmail email directly, does not use outlook and does not reroute her emails. She does not have any problems with emails arriving late to her Thunderbird inbox. We are both using same version. Any suggestions?

I keep getting authentication failure while connecting to server for different accounts every time I start thunderbird. It's usually just one and sometimes 2 accounts that fail. When I click on the individual accounts they start working just fine. I get this for yahoo, gmail, outlook and a couple of others. Something to do with the initial start of thunderbird I think.

Multiple Thunderbird Problems that started around 9/1. (Now 9/8/26) TB won’t properly download emails

   • Status bar will say “downloading 1 of 61”, pulse a while, nothing happens, then says “nothing to download”.
   • Yesterday there were no downloads 5 pm to midnight. Left on overnight in the AM there were 114 emails in box, 20 of them dated previous day 2:33 pm to 5:43 pm
   • Morning Inbox also contains 9 emails dated 8/31, which are duplicates of emails received on that date and placed in trash then.
   • It is a big business problem that I cannot rely on receiving emails in timely manner.

Many times cannot simply SEND email in TB

   • I will compose email, click send, and recently cannot expect send to be successful. Often get the message "Sending failed because connecting to Outgoing server (SMTP) failed"
   • Sometimes 5 minutes later I click SEND and the message is sent. Other times it will not send at all for hours and I am forced to use my gmail account to send an important email.

Have performed the fixes suggested online without relief

   • I have checked that the SMTP is correct. (Also sometimes SEND works)
   • Have deleted the file global-messages-db.sqlite 
   • Saved my profile, deleted the TB program, reinstalled TB, copied in my old profile.

I have set up 4 email accounts in Thunderbird. I tried today to set up another email account with the same domain. selected the New Account Button (email only); then pop up screen to add name of account user and users email address. next menu, TB was successful finding the server but a small yellow flag says "unknown hostname" but lists the 3rd party host, that there is SSL/TSL security and the user name matches the new account information just entered. Incoming settings looked correct. The next screen is Choose email account type and it was auto populated by TB and all info is correct. Next, enter password (for new account?) and TB fails to create a new account. Says Authentication error unable to log in at server. Tried doing the manual config. Outgoing server protocol shows SMPT when it should be IMAP (correct?) but the field is un-selectable. So results are same, Unable to log in to server.

the manual config screen has a host name field and it is autofilled with my company's name.domain but it is misspelled! Tried to edit but no success. I really need to get this new account up quick! So asking for any help available.

Hi Support,

For the past few days I have been using Thunderbird as my mail app for office 365 account and it has been working however today I have attempted to send an email and it has stopped being able to. I get prompted to re-enter the password go through the login and the 2FA and then get to the "You're all set" response page and when I go back to the thunderbird app I get prompted to re-auth again.

Are there any troubleshooting steps I can follow to find out at what stage it is failing?

I have it configured for smtp-mail.outlook.com with port 587, StartTLS and OAuth2 selected. A username is also configured.

I have many years and email accounts on my old WIN10 workstation running all POP installations.

I have a new workstation with WIN11. Is it possible to install TB on my new workstation with my accounts installed as IMAP and keep the same folder configuration? I have many email folders and filters setup on the old workstation installation.

I would appreciate any installation recommendations. I've been using TB for years and would like to keep as much of the current configuration as possible.
