Thunderbird Support Forum

The email address that I have used ever since email began has been [edited] @qis.net. Unfortunately, the inbox storage space on Quantum Internet Service (QIS) is only 1GB. I use Thunderbird for emails (recommended by QIS). The account with QIS is an IMAP account.

Yesterday at 4:40pm my inbox became full even though I have moved a bunch of the emails with larger attachments to offline folders within Thunderbird. That's when the nightmare started. No incoming emails can get delivered at this time. Have been in contact with QIS (I personally know everyone there including the owners. They're good people) It seems that we do not have a way to get into the inbox and remove files from their server (s).

After working all night trying to sole this mess, I have set up a new email address to maintain a form of communications on a major engineering project.

The new email address for me should be changed to : [edited] @gmail.com

Please make this change at Firefox. When I try to login on Firefox, it sends a code to the old, non-usable email address. Since the inbox at QIS is full, I can't read it to get the code to respond. If the code can be sent SMS to my cell phone, that would be fine. [removed phone# from public support forum] is the number to use.

I hope all this makes some sense at your end. I am not a guru with this stuff and a very dear friend of mine who was an "IT guru", as I called him, has passed away about 1 year ago.

I appreciate any help you give.

All I get now in my emails are links to the mesages received. This has changed suddenly within the past few weeks. If this can't be staraightened out I will change to another email provider.k

I occasionally get a Authentication Failed to Server (Outlook.com) and when it occurs it continues for 1-5 minutes then goes away again.

Is there any error logging proceedure that I can set up to see what the exact issue is?

I've tried running a parallel alternative email client (eM Client) and that doesn't seem to suffer in the same way, but I much prefer Thunderbird so would like to find out what the problem is.

Salve, mi sono creato una rubrica di contatti mail solo su thunderbird. Ho nel frattempo cambiato PC. Come posso copiare o trasferire la rubrica dei contatti dal vecchio PC al nuovo PC? Grazie, Gianfranco.

Yesterday I found that emails are not displaying in the folders. At the top alongside "Inbox" it says I have 28 emails but only 12 are displaying, and this is repeated in other folders. The attached photo shows another folde saying there are 35 messages in the inbox but only 8 displayed. Where are the others?

Also, now when I open the program no new emails appear and the "Get Messages" does not download any new emails.

I have not made any changes to anything .

I am running Thunderbird on another laptop and it is fine. Are there any fixes or do I have to reinstall the program?

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.

Each time that I open an email, another tab appears in the status bar: Thunderbird Privacy Notice. I need to manually delete them for each email that I open. This is a nuisance. How can I stop these tabs from cluttering my status bar?

I work pretty much exclusively using Unified Folders, in particular a Unified Inbox. Thunderbird 115.11.0 checks for new messages on schedule and downloads from all three of my accounts automatically throughout the day. But if I want to do a manual download, the little cloud-with-an-arrow checks only my primary account, not the other two. Yet when I right-click the little cloud, that identical icon purports to represent all accounts. Am I misunderstanding something? Is there a way to essentially replace the one little cloud with the other so that a right-click and second selection is no longer necessary?

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

I am using Thunderbird version 115.7.0(64-bit).

The Inbox is 15.5 GB in size as shown in the attached image file,Inbox Size.Jpeg.

The Inbox folder is not displayed as the attached image file,Folders.jpeg, indicates.

Please provide me with a solution to this problem.

I have been given an email account as a board member of a local non-profit organization. I have tried but cannot get it to work in Thunderbird. It does, however, work on my Apple devices (iPad, iPhone & Watch). I'm missing important correspondence by not being able to get on my desktop. Any help will be greatly appreciated.

I can not get emails anymore. They just suddenly stopped coming in. I can go to my ISP’s website and see my emails but can not get on Thunderbird. I suppose there is a problem with my account configuration but I don’t know what. Any idea what settings to check?

I have not received my new emails and have tried different options to get it to work. It also says I have 300+ emails in trash but they don't show up for deletion. I have tried restoring default, I tried troubleshooting and nothing has worked. It all started yesterday afternoon when I tried to get my emails. They are in the server but are not loading on my Thunderbird page

Since yesterday I am unable to receive mail. When I send a test email the message below comes up. Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent...

I have searched, read and tried all fixes on this topic already provided but nothing has worked.

Thanks in advance.

Our calendar in Thunderbird is currently not letting any new events be entered, is now completely blank of all entries and causing a headache as we have no access to information previously entered for next month and information from last month.

Any help provided would be appreciated.

i SET UP THUNDERBIRD ON MY NEW COMPUTER, SUCCESSFULLY, BUT THREE DAYS AGO MY WEB HOST/SERVERS UPGRADED THEIR SYSTEM. i SPENT THREE DAYS SORTING OUT NEW SETTINGS. CONFIGURATIONS, PASSWORDS, ETC, TO GET IT ALL WORKING, IT WAS DIFFICUL BUT IT NOW WORKS. HOWEVER, I HAVE MANY FOLDERS OF MAIL ,AND MAIL NOT IN FOLDERS, IN THEUNDERBIRD ON AN OLDER COMPUTER. i WANT TO IMPORT THOSE FOLDERS OF MAIL, AND ADD THEM TO MY NEW COMPUTER THUNDERBIRD INBOX SET UP, BUT I DO NOT WANT TO IMPORT THE OLD SETTINGS AGAIN!" THAT COULD BE A DISASTER. I JUST WANT THE MAIL AND THE FOLDERS. ALL THE VIDEOS i SEE ARE TO IMPORT THE OLD SETTINGS AS WELL. CAN I JUST EXPORT/IMPORT THE ACTUAL MAIL FOLDERS AND MAIL, AND NOT SABOTAGE MY HARD WORK BY CHANGING ALL THE NEW SETTINGS AND PASSWORDS BACK TO WHAT THEY USED TO BE IN THE PROCESS?? IM NOT THAT TECHY; WOULD GREATLY APPRECIATE YOUR ADVICE. THANKS, STEVE
