Thunderbird Support Forum

Can't get out of offline mode. It happen once previous but an icon was available and got back on. Now going to settings and nothing works. Surprisingly found nothing with Google nor Mozilla support. No email; big problem.

The offline option does not give off or on but option that I don't understand.

The file at the top shows offline and there doesn't seem a way to change (no check mark).

The moderator, 10 years ago, said uncheck on life or two blue line. No such think.

Computer is connected to internet. Shut down MAC and restarted. Still OFFLINE. I must be online but cannot download my messages.

Please help

Hi, I just reopened Thunderbird after my computer was shut down automatically after a Dell firmware update. I had 15 email tabs open before this -- things I wanted to go back to or that reminded me to do something. They are now empty! I have gone into Troubleshoot mode a couple of times and restarted Thunderbird. I've also checked the "remove addons (or something like that)" check box. No luck. Can someone out there help? I'm going to try restarting my computer now. Thanks!

I know this problem has been discussed extensively, but I can't fix it even after reading the previous posts.

I have an institutional email address that uses outlook.office365 server and mandatory two factor autentication. I had my Thunderbird setup with this, which suddenly stopped working one day on my office PC. I updated Thunderbird to the newest version, but the issue pertains. Currently I'm running Thunderbird 115.12.2. on a Windows 10 machine.

When I try to fetch my emails from this server, a popup window appears that asks for my institutional login credentials. When I enter them, a second window appears, asking for the two factor autentication. However, this window seems to be corrupt, as it does not contain any information, and and it's impossible to type in verification code, as there's no input area at all (see the first picture - note that I'm using a localized version of Thunderbird).

When I click on Privacy and cookies in the right bottom corner, then two lines appear (although without any labels), where I can type in my verification code (I guess that it is the second line, because it shows dots in place of the typed characters, as for passwords). A screenshot of this window can be seen in the second picture.

However, after typing the correct code and clicking on the grey button, the first window reappears, this time with my email address that keeps flashing forever and nothing happens. It does not even matter if I type in the right verification number or just anything, it produces the same behaviour. As a result, I can't log in to my mailbox, which is operational, because I can log in there through the web interface of outlook, and also from my laptop using Thunderbird 78.14.0. I also made sure that the server name and authentication methods are correct (outlook.office365.com, port 993, SSL/TLS, OAuth2).

Do you have any suggestion how to solve this issue?

Many thanks.

I have used Thunderbird for many years. I had a problem viewing a jpg file that I couldn't resolve and decided to uninstall Thunderbid to install it again. Mail is working smoothly but I can't access my multi-year Calendar. I've tried several alternatives with no solution and I really need help please. I'm in Portugal and I'm Portuguese. My English is Google Translate's English. Thank you.

Whenever I select an email in my Inbox which has attached files (of any type) i get this pop-up, one for each attachment. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-07-02-00-10-20-f3ab8a.png This has only been occurring since I updated to Ubuntu 24.04 and Thunderbird 115.12.0-2 If I click on the "Find more in Software" button I get a message 'Failed to execute child process "Gnome Software" (No such file/directory)'. I have searched for a solution but can only find a reference which suggests that the problem has something to do with Evolution, (the file handler, not Darwin's theory). Any suggestions? Cheers Ian

Updated Thunderbird to 117.12.2 on the 25 June 2024. Since then I am not receiving emails on my computer. I have actually sent some emails but they don't save into the sent folder and I have had a "Add security exception" warning occured when sending.

So problem is not getting new emails since the latest update was loaded. Thanks Neil

Using TBird 15.10.1 64-bit on my Windows 10 desktop system, I find under Tools | Address Book a down arrow to the left of Personal Address Book; clicking on it displays all my created address lists, which are available when I compose a message to send.

Using 15.10.1 64-bit on my Windows 11 laptop, the down arrow does not appear and I have no access to those lists.

Am using IMAP on both systems. Tried importing lists as a CSV file; no effect. How can I get access to my address lists on both PCs?

All morning I had been receiving and sending emails without issue. Then at approx 12:41 PM EST Thunderbird stopped working. I can send and receive emails through AOL to AOL but they do not show up in Thunderbird. I did not have any other computer issues and did not change any settings. Verizon told me it was an AOL issue, but I was able to successfully send and receive messages with AOL. AOL tried to fix it but ultimately said it was a Thunderbird issue. In the last 6 or 7 weeks I have had issues with Thunderbird. What is going on? Very Very Frustrating!!!

Unable to fix the side by side error, my only option may be to re-install Thunderbird or migrate to Outlook.

My question is whether its feasible to re-install Thunderbird and still preserve my old profile and emails. I haven't done any backups of Thunderbird but do still have all my emails on the server.

Thanks Lance

PS I have tried all the suggested fixes as shown in the following link to the side by side error: https://support.mozilla.org/en-US/questions/1439559#answer-1659630

I can send emails but when try to receive emails I get Login to server inbound.att.net with username topgun30@sbcglobal.net failed.

I installed the new version of Thunderbird, and it's strange. I can receive emails and send emails, but I'm getting an error message at the bottom right corner of my screen:

Could not connect to the mail server (and then it names my server name) The connection was refused

What do I gotta do to make this go away?

Ever since the last update of Thunderbird, my Junk and Trash folders are empty. When I mark a message as Junk or throw something in the Trash, the messages simply disappear. I have no way of checking the Junk mailbox for messages that might be there in error. I am also unsure whether my Trash messages are being deleted permanently, or whether they are in a hidden mailbox somewhere. Please help if you can!

I want to save all the email addresses in the inboxes and sent folders of the email accounts configured in Thunderbird to the address book. I estimate that there are over 400 email addresses across 5 different email accounts. Is there a way to save these addresses in bulk instead of saving each one individually?

I recieved emails from Microsoft to update Authentication to Oauth as support for basic authentication will soon cease. Whilst I have not been experiencing any issues, after following the instructions, also provided here:

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202,

I now have an unusable Thunderbird client.

This is because I am having to keep authenticating my outlook accounts (I have about ~100 email accounts). They pop up one after the other for each account.

I believe I went through all the troubleshooting steps but to no joy.

I did notice however, when the "Enter your credentials....." pop up box appears and I go through the motions of authenticating my account and TB against my Microsoft account, the following entry appears under the Settings > Saved Passwords > Saved Logins > "Provider" column for that account:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All https://outlook.office.com/POP.AccessAsUser.All https://outlook.office.com/SMTP.Send offline_access)

The credentials include a very long auto generated password starting similar to "M.C533_BAY.0.U.-........"

A couple of things to note now regarding the oauth entry:

1. It possibly does not always get created when re-authenticating 2. After quitting TB and then re-launching TB, it dissapears

So the solution would be to somehow ensure this entry is created and it sticks even after quitting TB, since for those accounts that include this I do not have get the "Enter your credentials....." pop up box.

Is this something TB can investigate?

Email source below -- in HTML mode the hyerlink is not being shown highlighted. Switching to Text mode it does show the hyperlink. So appears to be a bug in the HTML parser. Received: from 127.0.0.1
