Forum communautaire Thunderbird

A weird thing has started happening to my Thunderbird inbox in the last couple of days. Emails are showing as from a totally different sender. For example, a Google search on Sondheim has been "sent" by EDF (my electricity supplier) and some Groupon emails are showing as coming from people I correspond with. Also a Keto bread recipe from a low carb group I belong to has been "sent" by one of my work clients! More weirdly, I copied them into a subfolder on my inbox and they then appeared correctly. I have tried repairing the folder but it made no difference.

I recently updated windows and since then I have not been able to login to my emails and or recover contacts or calendar on thunderbird. I am able to login to my primary email but I have no contacts and am not able to login to my other 2 email accounts.

I can sign in with my google account, but when I come to the installation window with Pop3 and SMTP another password is requested. I don't know which, and there's no possibilty to get a new. Please help Jens

My old desktop used Windows 7 and I used Thunderbird as my mail. I had a tech help and transfer files to a new desktop running Windows 11. Mail came over but he said he couldn't use thunderbird for a reason??? and switched it to Spectrum Mail which I don't like. I would like to restart a thunderbird mail account again but don't remember my password and my old computer has been destroyed. Any way to do this without starting from scratch and losing all my old mail and contacts?

I have a Yahoo.ca email address and have been using Thunderbird to retrieve my email for years. For some reason, a window now pops up to Rogers.com and they want me to log in there. This is not a Rogers email address and it is separate from Rogers. I had this issue before and this forum managed to get me back. My settings are correct. I have deleted the profile 5 times and added it back after a computer restart and still nothing.

Within the last 6 weeks I migrated to Win11. I migrated my apps that would work and Thunderbird also. Got a recent update of TB. Finally MOSTLY disabled the bloody awful thread thing in TB (seems to be folder specific??!).

But ever since running on Win 11, I cannot stop TB from marking my messages as read even if I have never opened them. Even If I never use another device to connect with email. I try things and sometimes it works for like a day and then poof! : any email that comes in is read as per TB.

It is killing me. I run my biz on email and if it is unread I give it low priority. But turns out it is marked read without any action from me. I get a LOT of emails.

Really! I do no want to migrate to another email program.

I am fluent with regedit and can hack a .ini file. Point me in the right direction please.

help!

I've installed a legacy version of TB and been using it for some weeks, now. [52.9.1 (32-bit)] That's necessary because I run a legacy windoze OS.

I have an idea of how to make the Start Screen Layout easier for me. Specifically the accounts / mailboxes panel, where I [so far] have nine email accounts. The idea is that - under all-but-one email account - have these two folders:

• Inbox
• Sent

Then, under the email account I use the most, I will have

• Inbox
• Drafts
• Sent
• Junk
• Trash . . .

. . . . followed by all the necessary and appropriately-labelled subfolders.

Is there any reason that's a silly idea?

What's the Local Folders thing, at the bottom?

After nearly 30 years, Eudora's SSL settings have made it incompatible with current mail servers. Or so I was told.

Oh, I'm a geriatric, even if a little more computer savvy than some of my contemporaries.

My old Win 11 laptop died. So, since I had an SDD adapter, I removed SDD drive from the old laptop and connected it to my new laptop.

- I had already set Thunderbird on the new laptop so I have an existing profile. - I was able, using the Import tool, to get my address book successfully transferred from the old profile. - And while the old calendar name appears in calendar pane, I don't see any of my appointments. - I tried create placeholder calendar, then deleting all the other calendars and retried but still no luck.

I don't want to just copy and paste all the contents from old profile into the new profile as I don't need my old emails or email account data. So, what should I do? Thanks for any help in advance

Firebird is so slow now, that I can rarely receive the code that you send me. Have to take annother programm for that. Freezes even when trying to mark a mail or erasing it. WIN 11. The programm is working well at my wifes laptop also WIN 11. 2 month ago it worked fast and fine. Working in Troubleshooting mode does not show any spam ordner like before and it does not run better. I also downloaded the last version. No change! I would like to uninstall the programm but did not dare due to perhaps loose all my mails. Could you help me please? Thank you!

In trying to launch Thunderbird, I am now for the first time being asked for my primary Thunderbird password. I do not remember setting this up and I have no record of this. How do I reset this password so that I can open thunderbird? I have been using Thunderbird for several years now and have never previously been asked for a primary password.

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

To Whom it concerns, It has been about 4-5 days since I can't receive my e-mail. I have e-mail you different times with errors coming up. When I open my mail since yesterday an error now says error with acct. cray9@oh.rr.com. Another error occurred with the POP3mail server. The mailbox closes. Then a box comes up Thunder Bird crash reporter then I can put why and then restart my e-mail. It does try to load my e-mail then stops. And now my password box doesn't come up to put my password in. Last it says connection to mail.twc.com was reset then once again the mailbox closes. Please help, I have been a customer with Thunder Bird for years. Thank you!!

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.

Just shortly Thunderbird always asks for verifying the Google-Calendars when starting Thunderbird.

I already tried to change it to ical via private Calendar-address...

Why is this suddenly happening and how to resolve?

Good morning, for some time now, appointments on the calendar that were scheduled before I open Thunderbird have been “forgotten” and don't appear. For example: an appointment (or memo) at 8:00 a.m.; I open Thunderbird at 9:00 a.m., and the appointment doesn't show up. Thank you.

All of a sudden every time I open something in an email it automatically creates a new tab. When I delete what I have open it takes me out of my email account and I have to delete the tab to get back to my remaining emails. I have changed nothing so I am confused as to why it has recently changed.

Until recently the folder pane could be sized or hidden via the double-headed arrowed cursor. Shortly after the 151.0.1 update this stopped working. All suggested solutions have not worked. A full uninstall (Revo Uninstall) and completely new profile has not fixed the problem. Folder pane only responds to the menu setting and is only Open/close but no sizing.
