Thunderbird 커뮤니티 포럼

I have searched without luck.

Either every thread I can find is about a slightly different version of the question, or none of the answers have worked.

I use Outlook Express 6. I'd like to move over to Thunderbird.

I have several GB of dbx files that I would like to import/transfer/convert and be able to access in Thunderbird.

I tried to use the import tool in thunderbird, but choosing "Import from Outlook" gives me the error: "There is no email program associated to perform the requested action. Please install an email program or, if one is already installed, create an association in the Default Programs control panel." I don't see how this is relevant. Regardless, I have now selected outlook express as the default email action, but get the same error.

I have also tried the "Import from file" option, but the only options are "backed up profile", "calendars", "address books". It would seem to me that it would be common for people to move from Outlook Express to Thunderbird, so it seems bizarre to me that there isn't an option to import DBX files. I've opened DBX files in notepad before, I know they're just text, importing them should be a no-brainer. Do I have to write my own conversion program?

Greetings, I have Centurylink for my Internet Service Provider. They provide my internet service and email. I have been using Thunderbird for many years and know it quite well. My issue is this. About a year ago Centurylink had a major update with it's services. Since that time I've been having issues using Thunderbird for my e-mail. I'm currently using the 139.0.2 (64-bit) release.

Getting e-mail using Thunderbird is very slow and sometimes nearly impossible. I have to open the Centurylink e-mail and get caught up on e-mail using their e-mail service. They also want me to start paying for the e-mail service through Centurylink.net services.

Another anomaly is any sent messages I send using Thunderbird will not post to my Sent folder in Thunderbird. I use IMAP because my Desktop and Laptop share the same e-mail so I can have those readily available on each. I have been through all of Thunderbirds settings multiple times chasing a remedy to these issues without any results. This is very frustrating!

If I delete my e-mail account from Centurylink.net and attempt to use Thunderbird solely, would this be something you would suggest? I'm not familiar with how to SAVE Thunderbird e-mail files when changing ISP's or where the information is saved. That is very important to me before attempting too many changes in trying to find a temporary remedy to these issues.

I'm trying to hold out for any big changes for another year, due to getting fiber brought into our area and access provided to all customers in the next year.

I'm very excited about Thunder having e-mail provided exclusively. However, not seeing any target dates for this service, I'm trying to put off having to jump through two or three changes until our fiber is available.

Any help and suggestions would be greatly appreciated! Thank you in advance for the help!

PS. I have just donated another $20.00 toward Thundermail and Thunderbird Pro projects.

It is very very hard to find new message. Years ago was so easy. Now it is near impossible. Must select special filter to view only unread. TB suppose to make it easier, not harder.

To change color of text or background is impossible. Once I found that must choose the color and close color changer. I did it once and again no way it works. Toooooooo complex. Even when I see the chosen color, and close two not one windows choosers (why two?). Again it is eeeextreeemly hard and often impossible to change color of text.

I have a couple of hundred filters and one of them occasionally kicks in and unexpectedly moves certain messages to a new folder but I can't figure out which filter it is. Rather than me going through every filter manually, can't Thunderbird tell me which filter affected a given message? I'd like to be able to right-click a message and be shown the exact filter(s) which affected it.

The other day I received an email from Mozilla suggesting I move from Thunderbird ESR to the Release version (Windows 11). I backed up my profile and installed Release 139.0.2. The following error is now popping up periodically in Thunderbird: "The folder 'Inbox on [myemailaddress]' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I do not think this message is really related to disk space (there's plenty available) or file write privileges since nothing should have changed. I see that others have encountered this message where Thunderbird is trying to compact other folders. However, I did not see a solution applicable to my situation.

Thank you, in advance, for any insight in getting rid of this error.

I changed my Google account password just today. I have used Thunderbird on PC for Gmail without issues for years. I went into Thunderbird Saved Passwords and changed the appropriate line to the new Gmail password. I restarted Thunderbird and tried to send a test e-mail. I kept getting "Login to account Google Mail failed" with a box of 3 options, Retry, Enter New Password or Cancel. When I click on either Retry or Enter New Password, it doesn't give me a chance to enter a password and goes immediately into the same "Login to account Google Mail failed" box with the 3 options. I searched and read the support and one of the option is to remove the line from Saved Passwords and re-create it. I did that and tried to send another test e-mail. Now I'm still not getting a chance to enter a new password. I keep getting the box with the 3 options which doesn't allow me to enter a new password. There isn't a new entry in the Saved Passwords.

Strange thing is Thunderbird is receiving new e-mails fine. I'm just not able to send.

Thanks.

15.18.0 how to export to mobile from settings in the desktop thunderbird so i can use my android phone--if it will help, on my desktop there is no Export to mobile in settings!!!!!!!

Will Thunderbird Release make it any easier to migrate Thunderbird from Win10 to Linux (Ubuntu or Mint)... With 200 million PCs becoming obsolete in a few months, I would think Mozilla would have noted that many of us are going to migrate to Linux but moving Thunderbird has been a nightmare (still unsuccessful nightmare). I've followed all the directives and none seem to work... I've been using TBird since it started and have a LOT of emails I'd prefer not to lose so if I could just get my Windows profile to work on Linux it would be great... I know you're busy, but we are facing an Armageddon of sorts out here... Help! Thanks a million cheers pj

By mistake i set up Thunderbird to delete emails from my bigpond.com account, once downloaded.

Therefore Thunderbird contains all my old emails.

I want to restore the old emails to my bigpond.com account.

is there a way to export emails from Thunderbird?

Thank you for your help.

I have combined thunderbird and gmail, and it works different at my 2 pc.s, but that is ok.

But my original thunderbird relays on yousee and the adress from yousee.

What if I skip yousee?:

Can i still keep the email address from yousee to continue this combination?

I want to keep it, (the adress) if possibly, but not yousee??

This is the question ?

--,

Other words, not questions:

I must say: The configuration and the userfriendly way Thunderbird runs at pc is the very best - also the way You can mail to a group and answer between each other and all ( not easy in gmail)+ the way you can make maps= The worlds best.

But there are too many problems with yousee at the mobile, therefore I am thinking about shipping it.

( I also have Thunderbird at my mobile, but some new spams here, which does not shows up in Gmail or Thunderbird ...at pc.s) --- Best from Denmark/ Kib

Updated from 138.xx to 139.02 today.

Archiving from either of my two feed (RSS) accounts doesn't work right. I click archive button, instead copies to the archive folder of first email account in list.

Used troubleshooting mode to disable addons, still happens. Saw nothing in changelog to explain this.

A bug?

Since 5.18.2025 I get a "no message found" in my sent folders and other folders. "Find" will still find the messages and they can be opened, but I can't get the email folders to display. I know they are still there. Version 128.10.2esr. How can I get them to display in the folders?

Can I use Thunderbird to build an incremental local backup/archive of all messages transiting (incoming/outgoing) a webmail account ?

Any idea how to achieve this ?

My problem is:

• A POP3 account will miss all folders except the Inbox. (It's a pity that POP4 has not gained traction yet.)
• An IMAP account creates a mirror, not a backup. Remote deletions in the webmail account must not delete messages from my backup and vice versa.

detailed requirements:

• one-way sync only, since a local backup/archive must be built, not a mirror (two-way synchronization):
• Remote deletions must not cause local deletions (otherwise it would be a mirror, not an archive/backup).
• Local move/delete operations must not be reflected back to the mail server.
• Read‐only access to the mail server: no moves, deletes or flags remotely.
• All messages in all folders must be included in the backup: Inbox, Sent, custom folders, etc. Since POP3 can only back up the Inbox, I will probably have to settle for IMAP to include all folders.
• No duplicates: Messages must not be stored locally more than once.
• Messages must be stored as full offline copies locally (not just headers).

I am trying to get my existing email to my new laptop. I did contact Spectrum and all the settings are correct. Thunderbird has asked me to change my password. It just keeps saying that my sign on will not work. I am using Windows 11.

I am running Thunderbird ESR 128 as a snap on Ubuntu 24.04. I have several different email accounts and until a couple of days ago, when I replied to an email on account 2 or 3 it was sent as from that particular account. Now it is being sent as if from account 1. Trying to send an email as if from account 2 or 3 results in a failed-to- send message. I have noticed that when I look at the from field for accounts nos 2 and three the following is being inserted before the normal email address "NSIMsgidentity: 1d6 (or 1d7). Can anyone please advise me why this is happening and how to recover the ability to reply / send an email from accounts 2 an 3 as if from those accounts rather than from account 1? Thanks in advance

Hi,

When I switch from the Calendar tab to any other tab (Inbox, Address Book, Tasks, etc.) and then return to Calendar, the calendar always jumps back to 12:00 AM in the daily and weekly views. Previously, it would remember the correct time range I was viewing.

For example, if I’m looking at 8:00 AM–6:00 PM time period in the calendar and switch to another tab, returning to Calendar resets the view to start at 12:00 AM. I then have to scroll down every time to get back to my usual working hours.

Please restore the previous behavior where the calendar maintains its last scrolled/viewed time range.

Thanks!

I have two issues that are related to a buggy interaction between Thunderbird and Microsoft's email server.

Issue (1) When I send an email with my Outlook email address (from the Android app or from outlook.live.com, but not Thunderbird), my email address shows up as a jumbled mess in the sent folder on Thunderbird.

It appears to the effect of

IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+XXXXXXXXXXXXXXXXX+29_CN=RECIPIENTS_CN=XXXXXXXXXXXXXXXX@sct-XX-XX-XXXX-X-msonline-outlook-6f06c.templateTenant

(I have masked some potentially sensitive information).

In the sent folder on my Outlook Android app, my email address looks normal. It also looks fine on a browser in outlook.live.com. However, it's in the sent folder on Thunderbird that my email address is a mess.

Issue (2) When my Outlook email address is involved, the sending and receiving email addresses in the "correspondent" field are swapped in Thunderbird.

There are a couple situations where this swap happens:

1. Sending an email with my Outlook email account (either through the Android app or outlook.live.com, but not Thunderbird). In my Outlook sent folder on Thunderbird, the "correspondent" field shows my jumbled email address and not the receiving address, such as bob@gmail.com. Likewise, In the inbox of the receiving email account (such as bob@gmail.com) on Thunderbird, the "correspondent" field shows bob@gmail.com and not my Outlook email address.
2. Sending an email with any other account in Thunderbird to my Outlook email address. In my Outlook inbox on Thunderbird, the "correspondent" field shows my Outlook email address (this time unjumbled) and not the sending email address. However, in the sent folder of the sending email account in Thunderbird, the "correspondent" field shows up correctly (i.e., my Outlook email address).

These two issues are perplexing and probably related. Thank you for any help!

Dear Support Team,

I'd like to understand the design of S/MIME signature / certificate validation in Thunderbird. Lets's assume the scenarion that a message with valid signature has been received but the certificate expires very soon (next couple of days).

In my opinion, the behaviour of Thunderbird might be a bit missleading. As enclosed, S/MIME information says that certificate is untrusted, which is not really accurate. The certificate was trusted when the message has been received but now expired.

I assume that Thunderbird validates certificate only against current date. But we have the message original date in the headers. Validation process could be configurable, like in popular pdf readers (which date to use for validation), or even better it could execute 2 validations in case current date validation has not been scuccessfull and S/MIME information could cover this scenario that the signature has been valid while message been created / recived but the certificate expired. It would definitely reflect real scenario in more accurate manner.

I'd appreciate if you could let me know if there is a configuration possibility which I'm not aware of. In case it is not available, can you please advise how I could submit a proposal of functionality enhancement? In case, there are rules comming from RFC standards restricting the validation of signature in a way that has been described, I'd also appreciate this feedback.

In spite of the above remarks, I think that you did a vary good job with S/MIME functionality in thunderbird. It is far more user friendly and well presented to a user than in other email clients.

Best regards, Marcin
