Forum Thunderbird zajednice

I'm trying to add a new account to Thunderbird, but am unable to complete the task because Thunderbird never asks me for the account password and the authentication fails. It auto-detects the server setup, but since it doesn't prompt me for a password I get "Authentication Error. Unable to log in at server. Probably wrong configuration, username or password." and can't proceed. I'm trying to add a Yahoo! account.

A couple weeks ago, Tbird downloaded a second copy of all the emails in my inbox (3000+) when I asked it to download new emails. It would only stop when I shut down Tbird, but kept downloading again as soon as I hit the button to download new emails. Now, it has started doing it a third time. How do I stop it this time and in the future?

When I follow the instructions to save the files necessary to transfer Thunderbird to a new PC, this attached file explorer window is what displays. Going up 3 levels does not get me to where I need to be. Is there some other way, or do I need to upgrade Thunderbird on the old PC first?

I am computer challenged, shall I say. Thank you for your time and trouble, Dave Frank

It seems like T Bird only executes my retention settings when I open a folder. For example, my Trash folder has 3.2 MB of mail and has a 3 day retention policy set. When I click on the folder, it starts removing emails beyond that time frame and now the folder only has mail within the three day window and has only 28.7 KB. My question is whether there is a setting that will change that so that T Bird executes the retention policy for each folder when I first open T Bird, rather than waiting until I click on the folder. Thank you

Hello, I'm currently having a problem with Thunderbird version 15.9. I can no longer sign in to my Google-Account after I set new passwords and entered them in Thunderbird. Several attempts were unsuccessful. I then deleted all entries related to my Google account. Adding the existing account again failed. I received two error messages. Error message 1: “Waiting for authorization during sign-in". Error message 2: “The inbox server is already in use.” An other E-Mail Account runs perfect. I urgently need help.

I have entered the port number I have from Spectrum 587 but that does not remedy the situation. My email is an older Road Runner from Time-Warner. I've had no problems until the last few weeks and it worked for a couple days then the error was hit and miss. now it doesn't work at all. jslifer1@nc.rr.com very frustrating! I'll be 79 as of next week and I really don't want to go through any major stuff on this....Pease Help

I cannot get mail or send it from any of my accounts in Tbird. This just suddenly happened today November 13th, 2026 A day or so ago, the new update was installed but, this just happened TODAY so all was well for those days prior! I'm using Windows 7 and the update was 115.18.0esr (32 bit) Anyhow, I did what it said and deleted the cache and changed the number of cache from 5 to 1 but, nothing changed after I closed and reopened the program. So, I went to google which said that this is a known issue with this update so, I should uninstall this version and download and downgrade to the previous version. But, no dice. Still get the error message with 115.18.0. What do I do now?

Managed to delete my primary default email account. still have secondaru. therse are both gmail accounts that I access in Thunderbird. I lost everything for my main account. But I have been trying to add id again and at least start using iut again. I get so far tnd then I get windows saying that I have to log in using gmail/google accout. I have gone on the gmail phone app and changed that. I have gone into google aqccount on PC and changed that, but it still keeps happenng. I never had to log into google before. When I am able to look at my inbox there is nothing there the new messages are not being omported and I actually seem to have no real access to the account. Suposedly Thunderbird is linked to my google account, but I have no idea what the heck to do or how to do it evidently. Can anyone help? Is there anyone I can speak to on phone to walk me through things?

Hi everyone,

I have been using a OTENET (Cosmote, Greece) e-mail account (apel50@otenet.gr) in Thunderbird on a laptop for years. But since a couple of weeks I have a problem with outgoing mail. No changes in configuration.

=> Incoming mail: Works still perfectly via POP3 (mail.otenet.gr, port 995, SSL/TLS).

=> Outgoing mail: Consistently fails on mailgate.otenet.gr. Tested on port 465 with SSL/TLS and port 587 with STARTTLS, as well as via different network connections/hotspots, and just to be sure also on smtp.otenet.gr. The following error:

"Verzenden van het bericht is mislukt. Er is een fout opgetreden bij het verzenden van e-mail. De mailserver antwoordde: Reject, id=18742-18 - SPAM. Controleer het bericht en probeer het opnieuw."

I have already contacted Cosmote support, and they verified that the account status is completely fine and that smtp.otenet.gr is indeed the correct and active outgoing server. Even a simple, plain-text test email with a normal sentence gets rejected immediately by their server-side filter (amavisd / SpamAssassin).

Could this be related to a specific header, authentication method, or sender-identity mismatch in Thunderbird when communicating with modern Telekom/Cosmote SMTP infrastructure? Any advice on what to check would be greatly appreciated!

Warm regards, Anna

When clicking the "cloud icon" ("get all new messages") I would expect it to check all accounts. But it only check the account that is currently displayed (not the others). Is this a known bug? Is there a setting for this?

End user reported he is unable to forward emails. Through troubleshooting found the issue only in folders he named first name last initial for example "John S" were unable to forward emails and forward button did not work, but folders name with just first name "John" forward without issue. He changed John S type folders to John folder and forwarding worked in the renamed folder. No adds-on exist for this user as they are blocked for our end users. I had him check Error logs and got the following error message:

Uncaught (in promise) NS_ERROR_OUT_OF_MEMORY: Component returned failure code: 0x8007000e (NS_ERROR_OUT_OF_MEMORY) [nsIMsgComposeService.OpenComposeWindow]

My emails are being sent twice to the recipients. To notice the problem I've had to read the message exchange from another client, as from TB it is impossible to see the issue. In fact, from TB it appears as if the nessage are being regularly sent once and appear just once in the Sent folder. I had unchecked the "Copy to sent folder" option, but this way I have no way to see sent messages from TB, which seems like an importante feature being lost, so I would like an alternative method. For clarification, I repeat: messages do not appear twice in Sent folder but are delivered twice to my recipients. From TB itself it wouldn't be possible to get to see the issue. Thank you for the help.

Edit: I should add that this problem ONLY occurs when I'm replying to a message I received.

Since yesterday, I am being asked for a password to access my emails. This is the first time this has happened to me and I have no idea what my password it so I am unable to get into my account so not receiving emails. What can I do?

Emails are still coming through on my gmail account. ([redacted]@gmail.com)

I guess I won't know if anyone replies to this thread as my emails aren't being received.

Would be grateful for any advice.

I recently setup a PC running Ubuntu with Firefox and Tbird. I normally use Pegasus Mail under Windows, and Tbird has a similar look I'm familiar with. But I got into a mess with Export/Import. My default Tbird install was for an IMAP account and she had already setup folders, received mail, created folders and posted mail into a local folder folder tree. I hadn't realised this and decided I prefered POP which was running on my other mail clients. In my merry-go-round of abandoning IMAP which I thought would be just changing server credentials but was so hard I started from scratch with a clean Tbird install. I used Export/Import and each time Import was creating duplicate local Folders until my original folder tree became a real mess. It does the same even though I only now have a POP server account. I'm not convinced deleting duplicate folders with mail content actually deletes them either, because folder size inside the profile appears unchanged.

At the same time as using Export I also made backup copies of the profile in the hard drive Tbird folder. When I retrieved a profile backup and copied it back to the Tbird folder, the folder tree was what I expected from a restored backup - Exactly as it was before, with all local folders containing emails.

I am wondering now if Tbird Export/Import isn't what I would regard as Backup/Restore, but appends folders to existing as duplicates without replacing and overwriting? Anything to help me understand the Export/Inport function would be helpful? Thanks

i am migrating from Outlook to Thunderbird and cannot see how i can migrate my tasks: i have trawled the internet but can only find out-of-date info about old versions of TB or using 3rd party tools: how can i sync TB tasks with Outlook or at least import tasks from Outlook for access in TB?

I've been using Thunderbird for about 15 years. Just started it up this morning to check my mail and it updated itself to version 160.0 (64 bit) code name Meadow. All seemed fine until I tried to search my messages and noticed that the interface was completely changed as compared to what it used to look like. No matter, I entered a search filter (Subject contains USPS) and clicked on the Search button. Nothing happened. No indication of progress, no results, nothing. What's more significant is that it returned no hits when searching my Inbox, even though that mailbox contains about 50 messages with USPS in the Subject line.

So ... what happened to the Search Messages function?
