Thunderbird Support Forum

Hi, I updated my version of Thunderbird by downloading the latest version and installing it as opposed to allowing Thunderbird to automatically update. The basic reason was my old version didn't support OAuth 2.0 which I needed to continue using my gmail account. After the update, I had 2 problems. First, my address book was empty but I have solved that from a backup Profiles folder I have. The second problem is when I start Thunderbird I get the following error message in the pane that would normally show the last email in my inbox:- "File not found

The file mailbox:///C|/Users/blogs/AppData/Roaming/Thunderbird/Profiles/ohv7zad7.default/Mail/Local Folders/Inbox cannot be found. Please check the location and try again."

The 8 digit default file is showing a different 8 digits to my actual Profiles folder. What do I need to do to prevent the error message appearing every time I start up Thunderbird, All my old emails are appearing as they should. Thanks PL

Login to my Thunderbird account has failed for the second time in less than a month. The first time it happened, the system seems to have fixed itself. This time, it is locked. See the attachment showing the error message. I vaguely remember being advised a few years ago to delete something in my TB and reinstall, that the content of my account is stored elsewhere and would reinstall. Is that correct?

A few days ago I got error message from Thunderbird: "Sending of password for user crangard65@gmail.com did not succeed. Mail server pop.gmail.com responded: Username and password not accepted.

Later the same day, after shutting down PC, got into Thunderbird without any problem. Has been OK for a few days then yesterday the same error appeared. I have no problem accessing my gmail directly via Firefox using my usual username and password.

Any suggestions?

Operating system is Linux 4.15.0-163-generic and Thunderbird version is 78.14.0, Build ID 20210901192859

Thank you.

I was able to login to all my gmail accounts via thunderbird yesterday, no problem. Today several, not all, of my accounts are giving me a "login to server imap.googlemail.com with username <username@gmail.com> failed. Retry/ Enter New Password/ Cancel. I try entering the password and no luck. I login with the same password via Firefox to gmail on web and it works fine.

Whats up?

For several days I get the message "Login to server imap.gmail.com with username alansharp26@gmail.com failed". This seems to be since the following update has been installed: Thunderbird 90.10.0 (20220525135609)iNSTALLED 6 June 2022 , 22..22.43. I can receive emails using Outlook on my laptop, and also on my phone and iPad. I have checked the settings and they seem correct.

I’m having trouble sending mail with my gmail account. Have tried authenticating with Oauth2 but does not seem to work. Incoming mail works fine. Have tried rearranging settings but nothing works. Any help would be appreciated.

My email housekeeping is atrocious, and as a result, I have stored loads of emails with large attachments. As my inbox capacity fell, I learned to detach files and store them separately, but that doesn't solve the historic issue and I am at 95% capacity again. So I need a simple way of identifying the emails with the largest attachments (>5MB) without searching all my folders one by one. Any suggestions welcome!

Win7 AMD quad core 64 bit desktop. A few days ago, Tbird 91.10.0 started failing login to both my gmail accounts; wouldn't download mail. When I checked account settings, the 'oath2' parameter had been changed. I re-selected 'oath2', and re-entered my passwords, and everything worked (getting and sending email, both accounts). Last night, when I tried to *send* an email, I got an 'enter password' popup. Entering the password (same one that worked to get mail) did not work, for either account. Today, the problem persists after rebooting, etc.

Gmail's web interface allows logins, receiving and sending mail for both accounts on the same computer.

The seemingly most applicable (closed) thread says to, among other things, enable cookies, but gives no direction as to where that setting is located.

Any thoughts on cause or cure? As I said, this failure just started 'out of the blue' a few days ago. I've used Tbird for many years without any of these issues.

Thanks for any assistance, Charlie

Outgoing mail stalls. The blue line goes across from left to far right and then stops. A "message sent" does not appear. I have waited for 30 minutes and the stall persists, even with a short test message. I turned off my antivirus (Bitdefender) and firewall. Incoming mail is fine.

I have another computer that works well for both in and out mail. Both computers use the same ISP (Netfirms) and have identical outgoing server settings, except for the email address.

Your help is greatly appreciated!

I have two different outlook email accounts.

When configuring them, I cannot send emails. The SMPT server user name is the same for both and there is no way to save two different user names.

Please help.

One account is hotmail, the other uses a personal domain name. The accounts work perfectly outside Thundirbird. The problem is when I need to send an email.

Thank you.

I have four Gmail accounts which I'm phasing out because of the absurd Google policies and convolutions. I've added four new accounts with another, my own mail hosting service. all the four Gmail accounts I have set to forward all to thee new accounts.

The problem is every time I start up Thunderbird it defaults stubbornly to the previous Gmail account which subsequently it cannot log in and for a password.

I tried everything, setting the other account as default account, unchecking server settings [i.e.check for new messages at start up].

Since I have much (downloaded) information still in subfolders that I need to access from time to time I have not yet deleted that account.

Nothing seems to work, every time I start Thunderbird it immediately goes to that previous default Gmail account and then prompts me for "mail server password required".

The strange thing is that the other remaining three Gmail accounts which have identical settings do not create a problem.

how can I make this stop for once and for all?

Hi,

TB 91.5.0 on Windows 10 (with profile folder excluded from virus scan)

The latest update to seems to have resurrected a problem with saving copies of sent emails. Sending works fine, but copying of the sent email to the sent folder causes the send dialog to hang. Disabling the "Place a copy in:" option in account settings eliminates the problem. Using the "Other" option to place it in a local folder works *that is not part of a unified folder* works OK.

I have tried repairing folders and deleting the sent files inside "smart folders" in the profile, with no luck.

Hello,

since a while my Thunderbird stopped downloading any mails. Instead it always asks to type in the passwort again but also after doing that, it just doesn't load any new mails. But I also never got any other error message. I use two different email providers (gmail and gmx) and neither of them work any more. I tried updating my Thunderbird. Now I have version 91.10.0 (64-Bit) installed but it still didn't get any better. Then I thought it might be due to the OAuth 2.0 thing that gmail now uses (which still wouldn't explain the problems I have with my other email provider), so I checked for the necessary preferences and the passwort it was indeed not set to the authentication method OAuth. I changed it and then the prompt asking for a passwort changed to the one from gmail. But even after typing in the correct data and clicked on "allow" for Thunderbird to use the necessary gmail data, it can't connect and gave an authentication error. Now that I tried to make a screenshot, it doesn't even do that anymore.

I use Windows 10 Home and I didn't change anything that could have caused this and all the account settings should be correct.

So, I don't know what to do anymore and I didn't find any other threads fitting this problem. Can someone please help me?

Cheers, Nadja

For some reason after running a Windows 8.1 System Restore, Thunderbird no longer worked. It kept producing the following message: "Thunderbird is already running, but not responding. To open a new window, you must close the existing Thunderbird process or restart your system."

The problem was that Thunderbird was actually NOT running. Nor did it appear in Task Manager so I could end the Task. Restarting the system did not eliminate the problem. Nevertheless, I decided to save the Thunderbird Profile for the email messages that it contained.

I then downloaded and reinstalled Thunderbird and replaced the Profile with a version I had saved several weeks ago. This solved the problem as far as Thunderbird working is concerned. However, I lost all of the pop emails after date of the weeks old profile I had saved. The missing emails were from two pop email accounts.

In the Profile that was causing the initial problem and that I saved, the missing emails appear to be present. However, if I copy the Mail folder from that Profile and replace the Mail folder in the Profile that now works, the emails do not appear. Rather, only the names of the two pop email accounts appear with none of the account folders, i.e. no Inbox, Drafts, Sent or Trash folders and their contents.

Is it possible to copy certain files/folders from the problem Profile and replace those in the Profile that works in order to recover the "lost" emails. Copying all of the content from the Problem Profile simply causes the same issue with the "Thunderbird is already running" message.

I am running Windows 8.1 Pro (64bit). The current version of Thunderbird that is now working is 91.10.0 (64 bit). Assistance to recover the missing emails would be greatly appreciated as some of them are rather important. Thank you in advance for considering my issues.

DKIM is configured correctly, mails result in a DKIM pass on outlook.com and other Microsoft services as long as a HTML signature with a link and image is not attached: dkim=pass (signature was verified).

If however a signature is added, e-mails fail with dkim=fail (body hash did not verify).

This only applies o more robust signatures, which contain website links and/or images. Postmastery covered the issues with MIME and Outlook DKIM status, and I assume that improper MIME is the culprit in this scenario.

This seems to apply exclusively to MS services, as mails with signatures get a DKIM pass on all other e-mail providers I had checked.

Dear Community,

I am trying to set up my organizational email address on Thunderbird. I am able to receive emails just fine. But when I try to send, I get an error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: SendAsDenied; {redacted}@hotmail.com not allowed to send as {redacted}@lehman.cuny.edu; STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message [BeginDiagnosticData]Cannot submit message. {redacted: a long string of letter, numbers, colons, commas, and spaces} [EndDiagnosticData] [Hostname={redacted}.PROD.OUTLOOK.COM]. Please check the message and try again.

I think the error may be due to one or both of these complicating factors: (1) I also have my Hotmail account set up on TB. I think both accounts use Office 365. (2) My institutional email address and domain are NOT the same as the username/domain I use to log into this email account. To log into my institutional email from a browser, I go to outlook.office365.com and enter my login credentials: {redacted}@login.cuny.edu. This takes me to my institution's SSO login page. From there, I enter my login credentials, and then I'm directed back to Office365. But my email address is {redacted}@lehman.cuny.edu.

Even though my @lehman.cuny.edu account is selected as the "From" address in TB, the error message suggests that I am attempting to send from my @hotmail.com account. Weird.

In searching for answers, I found this page, but I don't think it solves my problem: https://support.mozilla.org/en-US/questions/1270491

BTW, I have tried a few different combinations of using the @lehman.cuny.edu or @login.cuny.edu names in the "User Name", "Account Name", and "Email Address" fields in the TB settings for this account. All result in similar error messages when I try to send an email from this account--or in some cases, losing the ability to receive messages too.

Here are the server settings I'm using in TB (I got these from the Office 365 settings after logging into my email account in a browser). IMAP Server name: outlook.office365.com Port: 993 Encryption method: TLS SMTP Server name: smtp.office365.com Port: 587 Encryption method: STARTTLS

I'm using: Thunderbird Version 91.9.1 Ubuntu 20.04.4 LTS

Can someone help me sort all this out please? I'd be very grateful!

I have a local folder that has about 950 emails in it and is about 9MB in size. Today, when I choose an email in this folder to view, it just says Loading... at the top and then there is a blank screen below. I have tried Repair Folder. I have tried creating a new folder and moving emails over to it to view them. Same problem happens in the new folder.

The odd thing is... if I choose to view the email in a new tab or in a new window... it displays fine.

Any ideas what I can do to fix this?

Thanks for your assistance

I have used Thunderbird for years, I think I may be forced to change! I have lost IMAP login Gmail, from Thunderbird, since the last update download (last email on Thunderbird is 6th or 7th June 2022 Thunderbird constantly says it cannot log in to GMail IMAP, requests to try again or get new password (for which it requires the password it will not recognise) Still using Gmail on my phone, have had to launch Chrome to use Gmail on my (old) iMac [running 10.13.6, High Sierra - can't update further], so I know the password is still valid. It is Thunderbird which seems to be the problem, here. Have read through various Problems/questions similar, but have not found a solution that helps

I had a similar problem with an update of Firefox, in that I was unable to use the browser - in the end I had to delete the browser, and several weeks later, re-downloaded. (This meant that I lost all my bookmarks etc, and had to re-establish passwords, but I'm now back to Firefox)

About a year ago, I was experiencing problems with the current-at-the-time version of Thunderbird which I have been using for ~15 years after transitioning from Eudora. After much frustration, I decided to move to the beta releases & the problem (long forgotten) went away. I thought that the stable release would catch up with me & I could revert to the stable versions one day but I understand this is not possible or advisable.

Q1 : Can I revert from v. 102 betas to the current stable ?

Q2: With the latest 102 beta 2 release (4 June 2022), all my tabs disappeared & I can not get them back. I may be missing the obvious but I can not see how to get them back. I tried reverting to beta 1 but no change. The update was done via the usual "help, about" when it prompted to upgrade. Help messages on the subject seem to refer to older versions where things were obviously different.

Clearly something went wrong & I am not sure if I can fix it myself or must wait for a fix. Any tips welcome.

I am now using gmail to collect my (multiple accounts) pop mail for me until the problem rights itself. I traditionally use pop as I am often offline due to location. This is also my first ThunderBird support question ever.
