Thunderbird Support Forum

Dear all,

Microsoft banned all basic authentication method from Office365 because these method does not support multi factor authentication.

After that, I reconfigured the the configuration by used OAuth2 method on latest version of Thunderbird (78.5.1 (32-bit). The result as follows: + Can not receive new email from Offfice365 (Alert: As attached file No. 1)

+ However, I can send the email normally with OAuth2 via SMTP

Please help me fix this problem.

Thank you so much for your support.

Hi all -

Just upgraded to TB 78 on Windows 10 x64, Build 2004. Noticed two major things:

Issue 1 -

All of the mail folder icons are no longer yellow. Just a stark white with a black edge. I attached an Image of the issue for review.

Issue 2 -

My Message Composition Pane is dark with white letters and most incoming text mail is the same.

I do have some dark colors set up under PC Settings -> Personalization but everything was working perfectly prior to this new release.

I attached Images of the issue for review. Note the "dark haze" over the HTML email.

No add-ons are enabled!

Any help appreciated! Kind of urgent to me.

TIA :)

We are moving and I will not be able to access my computer for 2 weeks. I need to know how to set up "Out-of-office" reply. Any help will be appreciated.

Recently, an important email was put into my spam/junk folder. It was from a sender and with the same subject line that I receive every week. I've just now read the article about training the filter and I will start doing those suggestions, but for now I need to just totally NOT filter anything as junk. Is there a way to do that?

Thanks. SweetTasha.

Hello! I added two gmail accounts to thunderbird (let's call them gmail A and gmail B), with the aim of copying all emails from one account into the other. However, I discovered I really wanted to copy gmail A over to gmail C instead. I want to remove gmail B from thunderbird, but that is my primary account. I am worried that if I remove an account, it will delete all content in my actual gmail account, which I don't want at all. Does removing an gmail account from thunderbird delete the content in gmail, or just de-link the account, which is all I want?

I cannot reply to or write a message to any Gmail accounts. Everything else is working fine. This may of happened shortly after I tried to create a junk and better filter my spam folder. Following other advice posts, I've checked and smtp is set to "normal password". Any help would be greatly appreciated, Thank you.

This same error message keeps popping up; SMTP error from remote mail server after end of data:

My mother changed her gmail passwords. She uses thunderbird for email. How do you change the passwords so that thunderbird will work and get her messages again.

There doesn't even seem to be an entry blank in the accounts pages to enter a password.

WHY HAVE YOU MADE THIS SO DIFFICULT?

Hi Team,

I have been using outlook for my mail. now i have switched to thunderbird. now i need all my mail item backup to be exported from outlook and imported to thunderbird.

I have already backed up outlook backup in .pst file format. now how can i need feed it into thunder bird?

please provide assistance.

I need to export a lot of emails from Thunderbird on an old iMac. It seems the import/export tool is not on the version I have so I have a problem. I need to get a plug-in to do this now. However, the version of TB is very old and I'll need a new version of Thunderbird to install the plug-in... So the question is - if I upgrade the old TB I have, will I keep or lose all my old emails? I need a sure answer to this because I can't lose these old messages. I don't want to import them anywhere, I just exported text or html for file storage.

Reading thru this forum I don't have high hopes, it all seems vague and complex (even tho we're now in 2021, no less, and ye olde issues rattle on and on). But a definitive answer would be useful to help me decide what to do. Thanks.

It's a small thing in this day and age of hacking and compromised web sites, why does the brain trust behind thunderbird make is SO HARD to change a password. NO instructions in help, search the simple terms "change email password" and NOTHING comes up. All I want to do is change my password on an email account. I can log into the email website with firefox but thunderbird cannot retrieve emails from that account, why? I am unable to change the password in thunderbird.

In version 78.0 (64-bit), as of 2020-07-15, headers are no longer displayed in messages. A clickable "1 more" is displayed in the "From" line but doesn't do anything when clicked and all fields are blank. Everything was working fine before the latest Thunderbird upgrade and system reboot. No other updates have been applied to my Windows 10 system. The message headers are definitely embedded in the raw message. I've also noticed that all folders now have a folder icon to the left of the name but that's probably just a normal update to the interface and there are two "Reply" buttons.

I'm having some trouble here doing a migration from Outlook 2019. Whether in the latest version or version 31.8, Thunderbird is not finding my Outlook file. Currently, the file is in a non-standard location. Where does it need to be? Will it need to be on the C: drive (which is rather small)? Or can it be found on the D: drive?

I've looked at other means of importing. I tried exporting from Outlook into a CSV file, but Thunderbird does not see all of the columns that were exported. For instance, the email addresses were not in that second column to be paired. That's rather useless.

Another option that came up in the search of previous answers was to export to vCard. It does not appear that I have that option in Export. And individually saving hundreds of contacts as vCards is not a particularly viable option, either.

What would you suggest?
