Thunderbird-Hilfeforum

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

• Download and install from "Download Thunderbird" link in notice.
• Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

Hi,

I had to update from an older version of TB to the latest due to the gmail security changes. I had an security/authentication issue that was brilliantly solved by a contributor here.

I have now realised that the update caused another problem ... my address book is empty. I have been doing much searching and reading about this and it seems that the problem is that there was a failure to convert the old .mab address file to the new .sqlite address file that the newer TB version uses. What I could not really find is the definitive answer.

I do not have any .mab.bak files in my profile folder. I have:

• abook.mab(44KB and filled with addresses)
• abook.sqlite (256KB and filled with zeros)
• history.mab (77KB and filled with addresses)
• history.sqlite (256KB and filled with zeros)

From what I read, the option open to me is to downgrade TB (all the others appear to rely on the .mab.bak files), export the address book, upgrade TB again and then import the exported address book. What I'm hoping is that someone here know a simpler way in which I can get the new TB to convert or "see" the old .mab file.

Many thanks.

Hi folks. I got a popup today advising me to upgrade Thunderbird to the newest version. I thought, "hey why not, I've been using Thunderbird for YEARS, I like it it's great"....so I did I can no longer connect either of my gmail accounts or my icloud account. Is this a known problem with the upgrade? If I wait a bit will "it fix itself"?

Any ideas?

Thanks!

Mozilla says it can't upgrade existing Thunderbird version and wants me to replace it with new version that I must download, as if from scratch.

If I do that, what happens to my settings vis-a-vis Gmail, which is where I fetch my mail?

Can some of you share experiences you've had using thunderbird with office 365? I may migrate a small business' email to office 365. I know 365 + thunderbird is possible as long as imap is enabled and that wouldn't be an issue. Mainly I would like to know how smooth it has gone for those that have tried it. I don't think the people at this org use the calendar feature of thunderbird. They would need email and contacts. I've used thunderbird + gmail many times and that combination works well.

I bought a new laptop because the old one died. Now I tried to transfer my TB data into the new computer. I managed to do it BUT... only one of my two MAIN folder data is there.

Last time I needed to do that when my laptop died it worked. Now despite me using the EXACT profile path/name (eg, C:\Users\XXX\AppData\Roaming\Thunderbird\Profiles\XXX) in TB's local directory at my new computer only one MAIN folder's data is present.

Does anyone know how to solve this issue?

Thank you!

I have set up a new server for all my web sites, including the domain I use for e-mails. I have changed the nameservers and e-mails are going to the mailbox on the new server. The e-mail address remains unchanged. I now want to set up an account on TB to access these e-mails. I've gone through the 'Add Mail Account' procedure, to the point where TB tells me 'incoming server already exists' and I can get no further. Do I need to delete the old account in TB and start again? I can do this, of course, but it means setting up a whole lot of preferences over again, which I'm hoping ot avoid.

Hi Team, I love TB and have been using it for a very long time. Until recently I was able to access my profile from both windows 7 and Ubuntu 20.04. The current versions are 91.9 on Ubuntu and 78.4.3 on Windows 7. I have 2 users (my wife and I) and somehow seem to have got into a real mess. My wife is asked all the "new install" account stuff from either windows or ubuntu. For myself I can open my profile successfully (bizarrely) with 91.9 on ubuntu but hit the install issue on windows 7. I have in the past messed around with profiles.ini with some success, but so far I havent been able to massage my configs so that I and my wife can access our old profiles.

I have looked though some of the existing issues but am hoping some kind soul will explain to me: a) can I use latest code to access the same profile b) how to configure the magic, please?

regards, Paul

Hi,

I've recently upgraded to the 91 version and the order of the account folders have changed. i.e. the email folders and the off-line personal folders are no longer in their previous order. How would I change the order.

I tried moving them, but they return to their original position after every reboot of thunderbird 91.

Additionally, is there any good docs about folder paths to learn more about archiving or default settings.

Thanks,

I have an existing Thunderbird account on my Windows 11 PC. I am now trying to open and access this same account on another PC with Windows 10.This is the message that keeps on appearing:

Unable to login in at server. Probably wrong configuration,username or password.

Any help would be greatly appreciated.

Thunderbird 91.9.0 says it cannot update and I need to download and install new version.

1. will this wipe out my current version? 2. How do I back up the old version/data so that it is recoverable?

I have things stored in some folders that I really do not want to have to singularly back up to other files and folders, as it would take me about 3 hours to do.

Any help apprecated.

I made the mistake up upgrading to the latest beta, not realizing it would convert my datafile to a different format and you can't go backward. I have done recovery over the years, but all the help refers to the old formats. Opening TB just causes it to hang. I have a large thunderbird file with a lot of files. I thought maybe a folder that I use a lot was too large so I tried splitting it in 2 but it has been unable to sync those since I moved them. Instead my whole computer hung and it turned out 400+MB was being taken by a folder which gets created when a folder can't finish compressing, but I had no choice but to delete that because my computer wouldn't function. In the past when a folder wasn't working right I would delete the folder index file and it would rebuilt the index and re-built that folder. Now all of my folders have mozmsgs but only some have sbd's. And the new folder isn't even there, although it's showing in my TB app when it opens.

I need to know what types of files I should delete in order to have my folders re-sync to the server.

Thanks!

I have used Thunderbird for quite some time. It recently crashed and had to be reloaded. When I did the install I checked the box for it to not be the default browser, it still loaded and became default. I deinstalled and installed several times with the same result. There is something Im missing. Any ideas?

Many years ago, I had two computers receiving email. Both received a copy of each email.

I am attempting a move from my old Thunderbird (38.5.0 in Windows XP) to a new 98.9.1 in Linux Cinnamon Mint. I sent an email to the mailbox. It was received only by the new Tb. I shut down Tb and restarted it. I sent a second email. It was received only by my old Tb.

The server settings are: Check at startup, Check every 10 minutes, Automatically download, Leave messages on server, Until I delete them."

I can find no option to allow the email to be downloaded by two Linux versions of Thunderbird, though surely that must be routine for those who receive their email both on a computer and phone. I need a POP solution, since I can be away from either version of Tb for some time.

Help, please!

I let Thunderbord fill out the first forms page, and the encrypted P/W is green. I also attempted to populate the "att.net" settings, tested it, and the P/W is green. After doing all this, I do NOT see a "Create Account" field. Not sure what to do now.

All the posts suggest

 Please see https://www.mozilla.org/en-US/thunderbird/all/

but that just offers the latest version (current 91.9.1) which won't run on El Capitan.

Other posts tell you to look at

 https://www.thunderbird.net/en-US/thunderbird/releases/

but that only gives you the release notes for the older versions, without any download links.

How do you get the older versions?
