Thunderbird Support Forum

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 have 6 gmail accounts which until last Thursday were all working fine on Thunderbird. However, I received an email for my main account from google telling me that they were switching on 2 step authentication, whether I wanted it or not.

After that imap stopped working for this 1 account. So I logged out of google for this account, and logged in again, using 2 step via phone. Still not working.

So I checked all my Imap settings with googles instructions, updated from the default smtp server, and still nothing.

Went back to google, and found I could switch off 2 step verification which I did. Thunderbird now partially works. I can download emails but when I come to send or save as draft, I get the error message as shown.

Windows 10, Firefox 91.4.0 (64bit)

Gmail refuses to allow Thunderbird to connect as it is "less secure" app. I used to have access using a "app password" but now even that does not work. Microsoft will be doing something similar this fall. So ThunderBird will not be able to work with Microsoft or Google mail servers. I installed OWL as a temporary work around, but I have multiple email accounts on several domains, and "ModernAuth" seems to use a web access and cookies, which means only ONE email address per domain can be used. What is the work around?

Hi: I use Thunderbird 38.7.2 on a MacBook Pro with MacOS 10.11.6. Thunderbird tells me that it is up to date, and that I am on the release update channel.

As of today, 9 June 2022, Gmail rejects my password, and re-entering it does not help.

I went into Preferences/Account Settings/<account_name>/Server Settings/Security Settings, Options are

    Normal Password
    Encrypted Password
    Kerberos/GSSAPI
    NTLM
    TLS Certificate.

Nothing about OAuth2.

Read that version 38 of Thunderbird is supposed to be OAuth2 compatible, so I'm stuck. As Thunderbird thinks it is up to the latest and greatest, I cannot update it to something newer. And I do not see a way to enable OAuth2.

The answer is probably obvious. just not to me.

after a recent upgrade (91.10.1) Thunderbird no longer has the question about remote content on the email view page. The one with options like show all remote from _ or show only remote content from _. Stilll has the exception section in Settings. Emails show embedded content on webmail. What gives?

I was notified by google that someone had my password and tried to log into my gmail account. I changed my password. Thunderbird requested the new password and I was unable to download messages. Then I tried to send a message and again Thunderbird requested my password. It did not accept the password. Now when I try to receive messages my password is not accepted and I get the error message Login to server imap.gmail.com failed. The choices are Retry, Enter New Password and Cancel. I enter the new password and get the same error. I went to Google help and I ensured IMAP is enabled. I clicked the link about Captcha. I've tried everything. I have the latest version of Thunderbird.

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.

I am getting desperate as the harder I try to sort this out the bigger mess I get in.

I think after about 20 years I may have to stop using Thunderbird but I do not know what other Email client to replace it with as they all seem to be confusing.

The archiving problem particularly relates to gmails but I cannot understand the gmail webmail system at all - it seems to sort emails into categories I do not understand or need or want to use.

I cannot send a screen shot easily due to the confidential nature of emails

I had to delete one of my email accounts (verizon.net) and now want to reinstall. When I attempt to add email account, I get a message "incoming server already exists"! The email account is, in fact, gone. Please help.

After suffering a disastrous loss of email caused by our web hosting service I've begun to use the Archive function in TB.

The objective is to not lose emails caused by others than myself.

Where are TB Archive folders located specifically? (yes, I understand they are somewhere in my default identity)

If I make a copy of the Archive folder contents located on my computer, put it in a stick drive (for example), delete the entire Archive folder contents located on my computer, can the backed-up folder contents be copied back to the former so that the emails will appear in TB as before?

Or, perhaps you can suggest a simpler way to backup emails?

Thanks,

Craig

I have started to have emails disappear from my in box. I have been in touch with my internet provider with no luck as they think it may be some thing with in your system. I am not what you would call computer literate so I have no idea what is going on. Any help will be gratefully received Regards Geoff Chatfield

The spell checker is constantly using English (USA) and not English (UK). No matter what I set it to it reverts. I suspect every time there is an update it does this and it is extremely annoying for anyone living this side of the pond (In the UK).

PLEASE can we have English (UK) by default. I notice when you add it to the list of languages in settings the USA version cannot be deleted.

Since updating thunderbird on the 7/7 I have noticed the filters are getting mucked up, they seem to get deleted and the global " Mark all folders read" is not working. I have done several restarts with addons stopped, and cache cleared, but it still happens.

Like many, I'm getting Authentication error using gmail. I had no problems on my old computer under Windows10. When moving to a new computer with Windows11, my main gmail did install. However, 2 other emails, I also need, will not install without this error. I'm using McAfee LiveSafe antivirus on the new computer. If I can't solve this, I'll no longer be able to use Thunderbird (which I like!).

Today my 102.0.1 has disappeared. TB has worked for me for decades including now on 102.0.1 which is the latest version. I've downloaded 102.0.1 again but still doesn't show up.

Been using TB for ages - love it - however it has recently stopped receiving emails - what is the cure? Reinstall? New update?

About your message below regarding 'Email me when someone answers the thread' - if the problem is that I am NOT receiving emails? Send a text?

suddenly Thunderbird email stopped working. I keep getting a request to input and change my password and have done that several time. I also have gone through all the steps to ensure all the info was correct and connected properly. My email works fine when I login through the internet. Passwords are correct, connection info is correct. My emails work fine on my phone. I have uninstalled the program but it had no effect. I am using version: 102.0.2 (64-bit)
