Thunderbird Support Forum

I suffered a BSOD on my fully up to date Win10 Pro (v 22H2, build 19045.4474)

Upon rebooting, Thunderbird is failing to open. The error message is:

   Unable to open the folder Inbox on xxx@example.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again.

There is no other process using the Inbox folder. I have rebooted and the error message persists. It looks to me like the more correct message would be that the Inbox or the profile is corrupted.

I see other threads asking how to restore a corrupted profile, but none of the answers are very useful. They all see to be tips on how to restore a backup of the profile at %APPDATA%\Thunderbird\Profiles.

If I had a backup of that folder, I wouldn't need to ask how to recover a Profile after a crash.

If it helps at all, when I opened the Error Console in Thunderbird, I see the following messages:

``` Uncaught Error: Component returned failure code: 0x8055000a [nsIMsgFolder.updateFolder]

There must be some tool that validates the Profile independently of Thunderbird.

I'm a freelance writer, and often when querying an agent or publisher, they ask me to send the first "x" pages of in the body of the email (NOT as an attachment), and they want it double-spaced. It's double-spaced in Word, but when I paste it into T'bird, it's single-spaced. I've tried everything I can think of, to no avail. Is there a solution or work-around?

I keep getting the following mesage, this has started all of a sudden, computer did a windows 11 upodate yesterday.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Sender Policy - Relay Denied 211.30.49.152 authenticated connections ONLY. OB303 e{391cd896-4e9f-4d6a-9932-850a9ace859b}. Please verify that your email address is correct in your account settings and try again.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

On 5th June I received the following message when I opened up my email.

Warning: Potential Security Risk Ahead. Thunderbird detected a potential security threat and did not continue to live.thunderbird.net If you visit this site attackers could try to steal information like your passwords, emails or credit card details.

I have not received any emails since then. Nor able to send any. I can receive and send my emails through my Mail provider- Telstra Bigpond and also receive and send on my Apple iPad and Phone. I have tried turning the computer on and off but this does not help although I am no longer receiving the warning message. Hope you can help fix this. Regards Dawn Howell

Yesterday, midday, my sent file stopped storing new messages after years of flawless service

I have tried: - closing TB and shutting down laptop and restarting

                      Under  Account Settings> Copies and Folders: unclicking "place a copy in" doing a test and then reclicking "place a copy in"  (directed to sent folder)

FWIW: 1.only thing I have done differently lately is create a Template

           2. Sent folder works fine on my on-line email ( I normally work with storing locally on my MacBook Air) but on-line email is not TB so likely irrelevant

I'm a newbie to Thunderbird. I've added an existing email account to Thunderbird, but it displays the emails with the oldest on top. How do I setup the Thunderbird app to display the most recent emails on top?

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

My aol.com IMAP is used directly only for travel. The same email address serves my Thunderbird POP email. Currently, ALL incoming mail goes to the AOL server. I cannot see the messages nor answer them on the local system. I store nothing on the AOL server. How can I get the incoming mail to the local email tool?

Any work-arounds?

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

I had to purchase a new computer and the set-up did not transfer my account of mozilla thunderbird files and e-mails. I downloaded the mz app and followed the instructions to Set Up Your Email Address and the Configuration was found in Mozilla ISP database. So when I selected Done, the prompt read: "Could not get OAuth2 details for hostname=imap.comcast.net." What do I need to do to retrieve my files and e-mails in the mozilla thunderbird website and transfer them to my new computer? Thanks

Hi

I recently changed my email address from johnbugler@phonecoop.coop to johnbugler03@gmail.com.

I receive Thunderbird 'flyers', and I want to ensure that they're sent to johnbugler03@gmail.com. If it hasn't been done already, please change my email address to johnbugler03@gmail.com.

Thanks and regards

Hi. My hard drive crashed. I have a new pc and the old drive is readable in a drive enclosure hooked up to new PC via usb. I have done the typical search for the appdata profile file, but I am not sure what I have here. I have attached a screenshot of the old drive and a global search on "Thunderbird". I am not sure where the profile file is residing. Any advice would be welcome. Thanks.

Recently the email display has been changed and not by me. At present I cannot receive emails as previously. Also I wish to revert to the previous display of my emails if possible. I can access email via the email.telstra,com site but I wish to stay with Thunderbird. I also do not get emails to my mobile as before

I would like to customize styling for recurring events in Calendar (115.11.1 on MacOS) without using extensions/add-ons. I enabled userChrome.css (`toolkit.legacyUserProfileCustomizations.stylesheets`) and the “has:” selector (`layout.css.has-selector.enabled`). In my userChrome.css, I added styles:

   li:has([alt*="Recurring"]) { background-color:grey !important; padding:1rem !important; }
   li:has(*[alt*="Recurring"]) { background-color:yellow !important; padding:1rem !important; }

Unfortunately, this seems to have no effect upon restarting Thunderbird. However, when I open Developer Toolbox (`Tools > Developer Toolbox > Developer Toolbox > Inspector` tab) suddenly everything works and the stylesheets are applied, but only until Thunderbird is shut down. Weirdly, other custom styles in userChrome.css work ok.

Is this intended behavior or a bug?

I keep getting this message sporadically: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hughes.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

I sent messages yesterday with no problem!

I can't see any issue with the SMTP settings. I've tried troubleshooting mode.

One of my email accounts (the main one) has stopped downloading to my asus Vivobook 15 laptop. My other two accounts are downloading okay and the account that is not downloading to my laptop is downloading to my Samsung mobile phone okay. Please can you help.
