I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295

   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I have my Mac and thunderbird set to auto-update, so I am not sure where the culprit lies. But my system did a Mac update and a Thunderbird update both recently. I'm now on Sonoma 14.3.1 and Thunderbird 15.8.1. When I started thunderbird it spun for 10 minutes. I thought it was locked up initially, did it again and even tried starting in safe mode. But after about 10 minutes, it eventually stopped. Problem was all my calendars won't display. I can add or remove either. The interface is barely responsive, and it crashes after a few minutes. I started Thunderbird from the command line to see if I could monitor the errors. I get about 100 of the following:

2024-03-10 14:06:22.361 thunderbird-bin[17189:518538] Rethrowing (from nts_ValueForProperty:) NSInternalInconsistencyException: Unhandled error (NSCocoaErrorDomain, 134092) occurred during faulting and was thrown: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" CoreData: error: Unhandled error occurred during faulting: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" ({ })

Anyone having similar errors, or any ideas on a fix?

Thanks,

I'm trying to move Thunderbird to a new PC. Both PC's are running Windows 11. I've followed the instructions for locating my profile. According to "Troubleshooting Information" my profile is supposed to be located at "C:\Users\photo\AppData\Roaming\Thunderbird\Profiles\k6i7koof.default-release\Mail\Local Folders". When I click on the "Open Folder" button, I receive an error message that the folder does not exist. When I try navigating to the folder manually, I can not find a "Thunderbird" folder under "AppData\Roaming". I've selected "Show Hidden Files/Folders" under Windows Explorer. I know my profile exists because I can access a set of Local Folders when I'm in Thunderbird. I'd really like to move those folders over to my new PC. Any help to find the profile folder will be much appreciated.

TBird 102.2.1 - just updated . . . and discovered that doing so caused several folder modifications I had just completed in the previous version disappeared. Really, really helpful . . . not.

Was in the midst of copying email files/messages to an external drive; 3/4 of the way through, in checking the "finished product" over there on the external, I discovered that -- regardless of what date the email had originally, TBird was changing all of the message dates to today's! That's really, really useful . . . I guess . . . in someone else's reality. My reality is that when I'm backing up email messages I have a reasonable expectation that they will each accurately reflect everything associated with the original(s).

So: How does one tell TBird to leave the original date(s) alone and copy the message(s) intact?

Guess it's now looking as if I will have to start this process all over -- and attempt to not seriously begrudge a program that makes such an unwarranted and unexpected change . . .

Thanks for any helpful information; appreciated.

Hi, am getting this error and am unable to use our new PC as this Thunderbird mail app is failing to migrate the profile from the other windows PC. Need your help asap on how to fix this. Not very technical, so need help. I updated Thunderbird to the latest version (115.11.0 32 bit) on my old PC before copying the profile over and loading Thunderbird on this new PC which has 115.11.0 64 bit version.

We just got a new computer because the previous computer died. I downloaded and installed Thunderbird on the new machine, which has Windows 11. I entered my name, email *@nc.rr.com and password. It had IMAP configuration on the screen and when I clicked 'Done', it gave me the error "Unable to log in at server. Probably wrong configuration, username or password." When I tried changing it to POP and clicked "Done", I got the same error.

There is a 'configure manually' link, but I do not know how to do that. Please let me know what I should do.

Hi,

I have several profiles in Thunderbird 115.9.0 (64-bit) on Win10 with each profile having few different email accounts which got created over a period of time since we had changed some mail service providers (mail hosting server) earlier.

Profile A1 -Email account a -Email account b (period Jan2022 - till date) -Email account c

Profile A2 -Email account p (period Jan 2020 to May 2020) -Email account q -Email account r

Profile A3 -Email account x (period Apr 2020 to Aug 2020) -Email account y

Profile A4 -Email account z (period Jan 2017 to Dec2019)

In reality the email account "b", "p", "x" & "z" are the same.

Question 1) So how ii can merge all my emails from different emails accounts located into different Profiles into a one single mail account and profile. Please note that the option to retrieve old mails from server is not there as the service provider has changed so i want to merge all past emails into one mail folder from local TB database only.

Question 2) After merging, there might be some duplicate emails in the same folder. How do i remove the duplicates and keep single copy.

Please advise.

Thnx & Regards Tejas

I am having trouble manually configuring an AOL email account (username@verizon.net). AOL's instructions say to manually configure the account. I tried to do that twice, once with IMAP and the other with POP.

Now, I have two email folders in Thunderbird that I cannot use. They are both empty because I get a message box that says "Login to server imap.aol.com with username@verizon.net failed." when I try to use them. When I use the same login credentials to login to the website mail.aol.com, they work.

I have to contact AOL as to why when I try to access the account with an email client (Thunderbird and Outlook) I'm getting password errors. In the meantime, how do I delete the two email folders created incorrectly in Thunderbird?

Thanks for your help.

Hi,

I have six IMAP email accounts that will cease to exist in a few weeks when I don't renew the domain/hosting where they reside.

Most of these accounts include invoices for purchases, and serial numbers etc that I need to have access to after the accounts will die, so just being able to read them offline. Even down the track when I inevitably build a new PC, I'll still want to have access to theses messages offline.

What is best practice for archiving or backing up these so I can still read them in future? Is there a way to archive so that I can read them in other clients in future? or I can only archive in a way that will be Thunderbird only?

Also... how do I get Thunderbird to allow me to read the messages from these accounts, without checking for new messages on these accounts, which would give error popups every time?

I've never had to do this before, and when I've searched around the results seem super confusing.

Any help would be greatly appreciated.

In case its relevant, my current Thunderbird version is 115.12.1 and running latest update of Win 10.

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

When I upgraded from MacOS Ventura to MacOS Sonoma, Thunderbird stopped working. Getting it to work the first time required me to use Apple's 2 Step Verification process to create an app-specific password. After the MacOS upgrade, that process was no longer available. Apple switched to 2 Factor Authentication, which is apparently different and incompatible with 2sv. The other websites and applications on my iMac have already switched to 2fa, and I'm not sure I can have both methods active on the same computer (but I've asked, Apple, anyway).

Is there a recent change in Thunderbird that would allow me to use 2fa instead of 2sv to access Thunderbird?

I have many years worth of emails in Thunderbird that I can no longer access. I can see the directory structure, and some of the email lists, but not the content.

Thanks for the help!

I recently updated Thunderbird to 115.3.3. When the update was complete it appears to have split my profile into two and created two of Inbox, Drafts, Sent, and Trash. I use Earthlink which is the name of the POP3 account. Now there are Inbox, Drafts, Sent, and Trash for "Earthlink", and a set for "Local Folders". Junk and Archives are only associated with "Local Folders", and "Outbox" shows up under a "Local Folders" header along with all of the folders I used to organize received messages. When new messages are downloaded they appear in "Inbox / Local Folders". Nothing appears in any of the "Earthlink / ..." folders.

I don't recall exactly what it looked like before but there was only one set of the primary folders, and the local folders I created to organize my inbox. I have attached screenshots of the the folder navigation pane, as well as the odd organization of the "Account Settings" tab. I am admittedly not an expert. Any help is appreciated.

Hello Forum!

My GMail account is approaching the 15GB limit and so I will need to migrate my email from one Gmail account to another, specifying a date range. range (i.e., any email sent before June 2015). Can Thunderbird help me to do that? If so, what is the process I need to go through?

Thanks in advance to all who reply, Dan

Unable to fix the side by side error, my only option may be to re-install Thunderbird or migrate to Outlook.

My question is whether its feasible to re-install Thunderbird and still preserve my old profile and emails. I haven't done any backups of Thunderbird but do still have all my emails on the server.

Thanks Lance

PS I have tried all the suggested fixes as shown in the following link to the side by side error: https://support.mozilla.org/en-US/questions/1439559#answer-1659630

My internet provider in Phoenix, Cox, has now handed its email services over to Yahoo. Prior to this, I accessed my Cox email (@cox.net) using Thunderbird. I am a technological dinosaur and am trying to figure out how to migrate my new Yahoo email to Thunderbird. I had a friend set up my Cox mail in Thunderbird but he is not available now. I am clueless how migrate my Yahoo mail to Thunderbird. I appreciate any help that the community can give me.

Will this work: 1. uninstall TB 2. Install TB and let it automatically set up my five (5) Hotmail email addresses using oauth2 3. Import my TB profile OR copy my profile folder (with all emails & address books) into new installation and still have oauth2 in server settings? OR will it revert back to old non oauth2 server settings?

Thanks in advance & God Bless

cox migrated their email system to yahoo but i dont believe yahoo uses usernames anymore, just email addresses so i cant set up my email to thunderbird since it requires a username and like i said i dont think one exists anymore.
