Upgraded to Sonoma 14.5 on iMac and when trying to open Thunderbird, I get the message "Thunderbird" is damaged and can't be opened. You should move it to the Trash. What do I do?

I am moving Thunderbird to a new PC, old was Win 10, new is Win 11. I installed Thunderbird on the new one, same version 115.10.2 though this is now 64 bit, old was 32 bit. I followed the instructions to move the profile by copying the Thunderbird folder onto aUSB stick then copying it to the new computer. The address book is there, but the local folders I had are not. Looking inFile explorer, I see that the Local Folders folder is there which contains all the folders I had, all populated, but there is also a Local Folders-1 there which does not, and this is the one Thunderbird is using. If I delete this folder, next time I start Thunderbird, it creates this folder again. I have obviously done something wrong, but cannot see what it is.

I am setting up a new Windows 11 Computer and am trying to install Thunderbird. I have downloaded TB (Thunderbird Setup 115.10.2) to my Download Folder. I double click on that file to run the Setup program, complete the user account information and TB and select Continue. TB completes the search and displays the correct account (att.net) connection information, SMP, POP3, Ports, etc. I select DONE and the Checking Password box displays. It runs for a few minutes and an Error message displays: "Unable to log in at server. Probably wrong configuration, user name or password." If I select Configure Manually, a window displays showing the correct configuration information (I have checked it four times). I will note that "Normal Password" has been selected for Authentication Method in case that is important. I have tried this method several times and get the same Error message. Any help will be greatly appreciated. Thank you.

I have attached a screenshot of the configuration window. Note: My account is with att.net but I am still using my old pacbell.net account that was merged with ATT many years ago.

Hi.

I've just installed the latest version of Thunderbird on a clean copy of Windows 11.

Thunderbird comes up with no buttons across the top (Get Messages, Write, Print, Address Book, etc).

I can't see an option for displaying them.

Any suggestions please?

Thanks, Dave.

I have a new PC. After installing Thunderbird onto my new PC, emails from my old PC are not there. Can these be recovered? I have a copy of my old PC hard drive files but not the actual PC. Thanks Jim Ferrier

I just installed Thunderbird on a computer, current version, and it didn't update my address book or contact list off the server. How do I do this manually as I could not find something saying to "download contacts" or anything like that. There is the "Directory Server:" option but I don't know what that is or how to use it. I didn't do that on my other Thunderbird installation (Work Computer). My email server is Mail.com if that matters. Thanks

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you

My mail is hosted on Hostpresto. Yesterday 'someone' (it wasn't me. I was in bed) gained access to my cPanel and email and deleted my only email address, then installed their own. All my mail gone. I was stupid though - I opened another email address with the same name as the old one and started Thunderbird on the pc. Of course, it synchronised to the empty folders!

Luckily I have another instance of TB running on another machine and it's all there - I am not internet connected there!

How do I bring the folders containing all the old mail from the 'safe' machine's appdata/roaming/thunderbird location to what will be my 'working machine' without it immediately synching to the server and deleting it all?

Thanks Andy

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

Been using Outlook, but am having issues. Decided to try TBird. Got the email part set up (far as I can tell). Calendar and Address book are a different story. Calendar: Using Google Calendar as primary calendar. Consists of an appointment, birthday, and holiday calendars. Created a new calendar and entered the URL for my Google Calendar. It showed up in TBird apparently OK. Created ANOTHER calendar and entered URL for Googles stock Holiday calendar. It also seemed to show up OK. Tried to do what I did with those calendars to add my Birthday Calendar, but Google uses data from Google Contacts to create that calendar. Can't figure how to add that data. HELP? Address book: Exported Google Contacts Data to a CSV file. Tried BOTH Outlook CSV and Google CSV exports. NEITHER produced a CSV file ANYWHERE Close to what TBird appeared to want, based on what showed up on the "fields" page that appeared after I chose the CSV filename. Moving data around in a spreadsheet is a Royal pain. Isn't there a Google Contacts CSV export file that more closely approximates the arrangement that TBird WANTS?

According to Help>About Thubderbird the current version is 115. But searches in my browser tells me the latest version is 105.

Am I not searching deep enough?

Thanks, James

Since installing Ubuntu 23.10 on my new desktop pc, Thunderbird is failing to see the account details in .thunderbird I copied all the files from my backup into a new account directory (/home/cfi/.thunderbird/y4xyxmli.default), a technique that has worked many times in the past, but not this time. Previously, thunderbird has simply taken the settings from the backed up files and used those to connect to my organisation's mail server. Any ideas? How can I force Thunderbird to read the old account settings?

Many thanks.

My email provider required me to migrate to a new server and advised setting up a new Account in Thunderbird. I did this and it successfully imported most or all of my stored emails from the old server. However, the import only preserved the first level of sub-folders (I have up to 3 levels). If I right-click on my email account in Thunderbird and choose Subscribe, I can still see the sub-folder structure there. Is there any way I can restore it so that it (a) shows the full collection of sub- and sub-sub folders in the tree; and (b) locates the correct emails in each sub-folder? If not, I face days of work to recreate sub-folders and move emails to their correct location. Thanks for any help!

How do I move all my message filters and address books from my Windows desktop PC to my Windows laptop?

I have three email accounts and ten address books. (The message filters use the address books to sort messages into folders.)

There are a bunch of abook* files in the root directory of the profile. Is it sufficient to move these to the laptop, or are they indexed somewhere?

There are msgFilterRules.dat files in many subfolders of Mail and ImapMail. Is it sufficient to move all of these into the corresponding folders on the laptop?

Is there an easier way to do either of these?

I am struggling with Gmail and Yahoo mail account in TB these few days. I hit almost the same errors from both. I generated app password for Yahoo mail, and put it in when setting up new account. For connection security: SSL/TLS For authentication method: tried with Normal password, Encrypted password, and OAuth2 However, I am seeing the expected authentication window pop up when trying the OAuth2. For all three authentication method: errors are always the same --- unable to connect to your IMAP server. I've followed another instruction to change maximum number of server connections to cache into 1 or 10. Error messages were the same imap one. So, what should I do/try for next?

After creating a IMAP email setup instead of the old pop3, I want to move my old folders over to the IMAP setup, but when clicking 'copy to', 'move to' or just simply dragging them nothing happens. No errors no nothing.

Whats wrong ?

I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.
