Thunderbird Support Forum

Hello,

I downloaded Google Takeout file, I was able to see it in my computer. But when I tried to import the mbox file into Thunderbird, it's not showing.

Please help.

I'm trying to read some old emails in an account from around 20 years ago that I have kept in Thunderbird the entire time. I stopped using the account, but kept it configured as it always had been with the old email saved in it. The emails are in several folders in Thunderbird, and I can see them listed when I select a folder, but the content of most of them is now invisible. For many years I upgraded Thunderbird and they remained visible, and I naively assumed that would always be the case. I think the visibility problem happened after a Thunderbird upgrade sometime within the last few years. Strangely, a few emails are readable. I think they're the last ones I viewed before I became unable to see additional ones I select to view. I believe all the data is still there, but I don't know how to read it. In the file system, here's what my Thunderbird profile Mail directory looks like:

/Users/myMacUser/Library/Thunderbird/Profiles/my-random.default/Mail account.server.name - TB Email Folder 1.sbd (empty directory) - TB Email Folder 1 (no file extension, apparently the file containing the email data. File sizes suggest they contain data) - TB Email Folder 1.msf (the index file, apparently readable) etc.

I'm using Thunderbird 115.12.2 on MacOS Sonoma 14.5. I tried several types of exports with the ImportExportTools NG extension, but it just exported zero byte or blank files for the invisible emails.

How do I read these folder data files?

My son has a Hotmail account that he accesses (of course) in Thunderbird. Yesterday he received an email from Microsoft that seems to suggest that he will not be able to use Thunderbird to access this account after 9/16/24. Is this true?

Dear

Subject to the following mail addresses: gunter.peeters@scarlet.be

We keep getting the following message when sending emails. An error occurred while sending email. The mail server replied: ip 213.49.30.104 blocked for relaying spam http://www.scarlet.be/pm/?e=f53&s=r&p=213.49.30.104. Please check if your email address is set correctly in your account settings and try again.

We are able to receive emails.

Is it possible to check this out?

Thanks in advance!

Kind regards Gunter Peeters

I am running a Mac Mini M1, on the latest OS, after upgrading my TB I have just had 2 force quit because of TB. As you will see it is using over 40 GB of memory, normally between 500 - 600 MB

Hi,

I used to compose my mails in the Montserrat font because my website is also in that font. Now I notice that the font is no longer available in Thunderbird.

Is there any possibility to import a font in Thunderbird?

Kind regards,

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

Heya:)

I am a webdesigner and I'm currently designing a website for a client that uses Thunderbird for his mails.

Previously, Domain, website, and email had been hosted with the former agency.

Now we are gonna split this up into 3 different providers:

Webhosting: Squarespace Domain hosting: Cyon.ch E-Mail hosting: Would be great to keep using Thunderbird :)

How can I ensure that my client can still use Thunderbird? Do I just need to change some DNS-records? Otherwise I will have to switch to gmail :(

Could I recover my message on thunderbird when I ever Setting : 1. Local Folder 2. Disk Space 3. Delete Message for 14 Days

I choose wrong setting, and my all of my message last 1 years have been gone Could i get my messages back? and where I can found the back up?

recently I learned how to point all accounts "archive" and "junk" and "Sent" to "local folders". But, Thunderbird continues to isolate archived messages into a separate subfolder within each of my several email account(s) - I work with a unified inbox and prefer unified "Junk" and unified "Archive" and unified "Sent"... How do I do teach Thunderbird to start using the intended folder structure ?

"Sending of password for user joebernard@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later"

^^This message comes up every time I try to send an email. It can be received outside of Thunderbird and to other addresses.

Right now I'm using 3 different email accounts on Thunderbird. All 3 of them are Office365 accounts. For some reason, 1 of the 3 accounts is prompted at least once a day, sometimes twice a day, to enter my password on the Office365 website popup that is used with the OAuth2 authentication process. It's very irritating, all 3 accounts are Microsoft Office business accounts. What would be the reason why it needs to authenticate daily? Is there no password manager to do this automatically once it's been entered once? Can I pick a different authentication method? What is the correct change to make so I don't have to keep typing in my password every day?

See the previous, now archive post about it.

If this option makes emails sent from Thunderbird to any other email client have arbitrary line breaks where the line changes in the view of the composer. Please explain to me like I am 5, why is this ON by default? I just spent hours wording and formatting a work email vital for my career just to find out it will most likely look like a poem to the person that reeds it. This mailnews.wraplength "feature" looks a lot like is there to signal to other non-Thunderbird users to use Thunderbird. I really really hope there is a good explanation for why `mailnews.wraplength` exists and is on by default.

I have over 35 email accounts, which I use Thunderbird to collect. Love Thunderbird for well over 2 decades!

I am wanting to have 2 of my email addresses to be downloaded before all the others. I have indeed successfully "moved" these 2 accounts to the top of my account list (Shift and mouse). However they are not downloaded in the order of the account list.

How do I accomplish this? Is it possible?

I created a ticket, and it auto-responded to run this by the Volunteer Community. I really want this to be handled by support, but welcome anyone to give me a solid answer.

We had a storm and now email doesn't work. We are a business and have to have email. I've went in and changed the Mozilla password and when go back to email it won't accept it. Emails aren't coming through. Can't sign in. What do I do?

I get the pop up that includes Add Security Exception

I am in Australia and Optus is my email provider. They have checked all is working at their end and suggest I contact Thunderbird which is why I am here.

Thanking you for trying to help
