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.

My computer crashed while Thinderbird was open and now all subfolder, all other accounts and everything else works well except my main Inbox part. I get gray picture with no messages, the wait cycle is constantly rolling and nothing happenes. When I opened preferences for the Inbox, there was no path. I tried to copy it from Inbox subfolder but can't write in that window. Tthanks in advance for your help Best, Alex

Using Thunderbird I upgraded not too long ago (in 2 steps) from Eudora to now version 91.11.0. I no longer see my address books (but see files abook.mab and history.mab (but not the .BAK versions as suggested on the internet)). Both files seem to contain data (when viewed in Notepad). How to get Thunderbird to recognize/use my address books?

Thunderbird keeps asking for address book password everytime I open thunderbird. I have selected to "save password in password manager" but it won't save it. It works after I enter it, properly syncs my address book, but it's frustrating when to have to copy from my lastpass every time I open it.

I have looked in preferences in saved passwords and it is not there. My imap, smtp and caldav logins are there, but no carddav password. Nothing else asks for password, just carddav.

Using: - Windows 10 Pro 21H1 - Thunderbird 91.11.0 x64 - CardDAV server is hosted by zoho (https://contacts.zoho.com)

I was reading email, archiving some and deleting others. After deleting a message, it started deleting all messages in the folder as if I were pressing "Supr" continuously. To stop that, I clicked on a folder. It showed the display "Are you sure you want to delete folder xxxx?" After clicking no, I went back to where I was reading and it continued deleting. So I closed Thunderbird. Opened a terminal window to test if keyboard was stuck but but there was no sign of a key being struck.

After reopening Thunderbird, there is no trace of the deleted messages. Those I manually deleted are in the Trash folder but those deleted without control are not. This makes me think it is not a problem with my keyboard or OS but something related with a bug at Thunderbird. Does this seem right or am I missing something?

I am using Thunderbird 91.9.1 (64-bit) on a clean new Ubuntu 22.04 install. All updates are applied up to date. I have not found any bug related to this and I do not know what to do. I am very wary about continuing to use Thunderbird.

I am on TB 91.11.0. It crashed a few minutes ago and now I can't start it. I have rebooted my PC. Doubleclicked on the TB icon, and it does show in the App List in Task Manager. I have never had anything happen like this before. Looking in the crash/events folder I can see that a report was made and uploaded. If it helps I can attach the crash report. How can I get TB going again? My whole life is in there.

Please any ideas?

Scott
