I see that others have had the same problem as me. My trash folder has many thousands of duplicate emails. If I block delete them it will take days to complete. So 3 questions 1. How do I stop duplicate emails in my trash. After deleting many reappear with the date 01/01/1970 2. Is there a faster way of deleting. I use select email>shift key>find last email>delete 3. Is there a limit to how many emails I can put into the block mentioned in #2

For many years, my wife and I have each used Thunderbird on our own computers. Several weeks ago, when my wife turned Thunderbird on, a new screen appeared that mentioned account setup and directed her to set up her existing email address. When she did, a home screen appeared that was significantly different than the one she had been using. But more than that, she lost all her saved emails and Thunderbird started to reload emails. The reloading ended with over 1800 “new” emails whose dates reached back for almost a year. Since then, after some work, the home page has been returned to its earlier look; downloading, sending and deleting are working as before. Missing are a few important, personal subfolders. We’ve tried a few things that we thought/hoped would return us to the point before everything went crazy. That hasn’t happened. Recently, we looked at the Profiles folder on each of our computers and saw something that, I think, is unusual and, I hope, might provide a way get her back at least some of what was lost.

The route to my Profiles is C: > Users > Me > AppData > Roaming > Thunderbird > Profiles In Profiles are two folders, one ends with .default and the other with .default-release. The only thing in the default folder is the file times.json. The default-release folder contains many files and folders, including the Mail folder. The Mail folder contains two subfolders: Local Folders and mail.comcast.net.

On my wife’s computer, there is only one folder inside Profiles. The name ends in .default. Inside that folder is the Mail folder. Within the Mail folder are six subfolders: Local Folders, Local Folders-1, Local Folders-2, mail.comcast.net, mail.comcast.net-1, mail.comcast.net-2. The Date Modified date for Local Folders is probably the date the problem started. Date Modified for Local Folders-1, mail.comcast.net and mail.comcast.net-1 is the same: a few days after the date for Local Folders. The dates for Date Modified for Local Folders-2 and mail.comcast.net-2 are the same, and change daily.

I’m hoping/assuming that the missing, personal subfolders are in one, or more, of Local Folders, Local Folders-1, mail.comcast.net, mail.comcast.net-1. What I’m asking here is: does anyone know of a way to easily locate and recover the subfolders and, then, move them into the correct location in Local Folders-2and/or mail.comcast.net-2.

Thanks for taking the time to read this long story.

I have several Comcast.net accounts that I have set up in Thunderbird. About 2-3 times per week, Thunderbird makes me re-enter one or more of my passwords, only for the comcast accounts. It says Authentication Failure, but I have not changed anything on the accounts, including passwords. Entering the same password works - for a while. Any idea how to stop this?

Every-time I open up Thunderbird e-mail Version 115.11.1 (64-bit) to access my Outlook E-mail Account, it pops open a box wanting me to enter my password! :-( I can enter it and mark that box to use "Password Manager", but it doesn't matter if I check that box or not, because every-time I reopen Thunderbird it asks me for that password again! :-( This problem just started in the last few weeks...... Once I enter my password, I can receive and send e-mails just fine, but when I close Thunderbird and reopen it, that popup box reappears again, where I must enter my password. (see picture I attached) If I just X out of it, I can't access my e-mail at all, as that box asking for a password, pops back open again asking me for my password AGAIN! Which by the way is 100% correct, as I can access my e-mail through Firefox, Google Chrome or Edge Browser just fine. I have used Thunderbird for years and have NEVER encountered this problem before, I hope you have a fix! I am running Windows 10 Pro Version 22H2. Thanks in advance! Keith

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

Good afternoon I have 2 accounts in Thunderbird - a gmail and a Yahoo. Both were running great from the time I set up Thunderbird about 2 weeks ago until yesterday when the gmail account stopped sending and receiving. The Yahoo account is still fine. I have not received a message in Thunderbird in my gmail account since, although I have logged in on the web and confirmed that there are incoming messages in my account.

When I attempt to send a message from the gmail account I receive an error message - "Add Security Exception". If I click "View" nothing happens. If I click "Get Certificate" the section "Unknown Identity" changes to "No Information Available". However, when I cancelled the message I noticed a new error message appeared - "Send Error Message" and when I returned to the main Thunderbird screen I noticed a new tab appeared "Certificate for smtp.gmail.com".

As you can imagine, I seem to be getting nowhere with this and as I am only an intermediate user with computers I don't know where to go next. Subsequently, I sincerely hope that someone out there is able to help me. Any assistance would be very much appreciated.

The following are my Thunderbird settings for the gmail account :- Incoming Server Server type : IMAP Mail Server Server name : imap.gmail.com Port : 993 User name : [myname]@gmail.com Connection security : SSL/TLS Authentication method : OAuth2

Outgoing server Description : Google Mail Server name : smtp.gmail.com Port : 465 Connection security : SSL/TLS Authentication method : OAuth2 User name : [myname]@gmail.com


A copy of the error messages as well as the Certificate are attached.

I want to move a lot of gmails to the Bin but keep them in local folders. An answer to someone else's problem said to be sure the local folder contains a true copy and not just a link, by checking that I could read it, but how do I do that for several thousand emails? Maybe they are all true copies in at least in one local folder? I need to remove a large chunk of 25000 gmails in All Mail to free up space on my hard disk. I was having problems with Global Search and followed instructions to re-index everything. Apart from taking several hours to index All Mail, I subsequently found that I could no longer get 2GB free space by using Disk Cleanup, the best I could get was about 300MB, which is apparently too small for Thunderbird to compact All Mail, or for Dropbox to sync with my mobile phone camera photos. The All Mail file in C:\Users\Michael\AppData\Roaming\Thunderbird\Profiles\hgwapwu4.default\ImapMail\imap.gmail.com\[Gmail].sbd is 4.5GB, and Important is 1GB

Here is a very strange problem: 1. all my notifications about interac are attributed to only one person: INTERAC e-Transfer: A money transfer from X has been automatically deposited. Under correspondents I have Y, no matter what X is. 2. When I do a global search for INTERAC, all notifications show up, but attributed to Z, different from X and Y. Further, Z only sent me an interac transfer once, maybe 10 years ago. Indeed, if I global search for Z, none of the interac notifications show up. 3. this is ONLY on Thunderbird, not at the server.

Any ideas?

I've read a few historic suggestions about how to resolve this, but I haven't been comfortable with what solutions were suggested as they didn't seem to comprehensively answer the questions, I'm afraid.

Until this morning's attempts to resolve the "running out of disk space" warnings, I had two mail accounts on Thunderbird - my old Hotmail account and my new personal domain based account. Both accounts had old emails (3/4 years' worth) filed locally on my PC pending my satisfaction that the new mail account was working satisfactorily. To try and resolve the storage issue, I deleted all the locally stored emails from my Hotmail account from within Thunderbird, then deleted the Hotmail account, and restarted both my PC and Thunderbird.

The expected reduction on space occupied by the .thunderbird folder didn't materialise - at all.

How can I get back the space so I can continue working, please?

I had 115.2.2 installed and all was good. I upgraded last night to 115.7 and things seemed ok but I am now on the road at Atlanta airport and I can neither send nor receive email. In the lower left corner of the display it alternately is stuck on compuserve: connected to imap.AOL.com or my other server eberger35:connected to imap.comcast.net

If I try to send a message from either my compserve/AOL, or comcast, or gmail accounts I get this error message:

The message could not be sent because the connection to outgoing server (SMTP) smtp.comcast.net timed out. Try again.

If I try to send from the compuserve or gmail accounts the message will reflect that server SMTP has failed instead.

I think everything was working at home before I left, but I'm not sure if I checked mail after I upgraded. Perhaps the problem is the Atlanta airport Wifi, but I won't be at my destination till much later today and thought I would post this now in case someone has an answer. I will be able to get the reply on my iPhone. Thank you.

Good morning. I need help with sending emails in Thunderbird. The problem has existed for a couple of days now and is confusing as some emails are sent and others fail. I am receiving mail OK. Details of my setup are :- I am using a HP All-in-one desktop running Windows 11 with Norton 360. My Thunderbird account settings: Server type: IMAP mail server User name: ****@gmail.com Server name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication: OAuth2 Outgoing Server (SMTP): Google Mail – smtp.gmail.com (Default) User name: ****@gmail.com Port: 465 Connection Security: SSL/TLS Authentication: OAuth2

The problem: I only recently set up Thunderbird and at first it seemed to working OK. However, now when I try to send a message, after some time, I the following error message :-

"Send Error Message Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

What is particularly confusing is that some messages are being sent. I have tried several fixes that I found from the Mozilla, Google and Norton web sites but none of the fixes resolved the issue. Any assistance would be very much appreciated.

Regards Mike

PS: I have 2 email accounts set up in Thunderbird. I just tried sending a test message from the Gmail account to the Bigpond account. From the Gmail account it appears to have been sent but in the Bigpond account an error message appeared as follows :-

"Could not connect to the mail server smtp.telstra.com; the connection was refused."

I don't know if this is a related issue or I have another one to resolve.

I installed Thunderbird and eventually got it working. I download with IMAP and upload with SMTP. TB did a great job downloading gobs of email from Gmail and converting the labels into folders. In a couple cases, it created folders, but none of the emails with that label were downloaded into the folder. FOr example, there is a folder 'PE' and a subfolder " CD Ads'. Emails are present in both. However, in TB, 'PE' is lighter grey and italicized and empty.

The folder structure is not an exact match to the label structure. For example, in the labels, I have an 'Employment' label with 5 employers underneath it. None of the employers made it into TB.

I have a few other oddities too, but lets start with these. I did end up using a normal password to access the account, as 0Auth2 would not cooperate.

Thanks for you insites!
