I am having difficulty getting certain emails. I am told by the sender that they "bounce back as a spam warning" Sometimes I don't know the emails I am NOT getting until I'm told. Two my daughter tried sending me an email and it took over 24 hours to get and she was getting bounce back messages. I can't get "NextDoor" notifications, a store in London couldn't email me, a local contractor couldn't send me an email, etc.. It's random who can't email me, but it's becoming increasingly concerning. It's only certain, legitimate emails. I still get all the spam! Where should I begin? I'm on Windows 10 Pro, using a yahoo/att email through Thunderbird. thanks for any suggestions! Cindy

Checked everything. Not sending after upgrade. Is sending in troubleshooting mode.

No add-ons.

Not anti-Virus or firewall issue because I shut them down. to test. With both on it sends in troubleshooting mode.

I have spent many hours combing thru possible solutions.

Please help. TIA.

Hi,

I have just setup a new Office 365 account in Thunderbird and when I try to send an Email from the account, I get the attached error message.

When I click on "Enter New Password", the window goes away for a moment and then pops up again. There is no chance for me to put in a new password.

I know that I need to use an app password when not using Outlook which I have generated in my Microsoft account settings.

I have tried to go to "Settings -> Privacy & Security -> Saved Passwords" and have deleted all Microsoft related saved passwords. When I access my Email account again, I get prompted via the web login of Microsoft (i.e. different from the attached error message) and the app password I generated doesn't work, only the general password for my account works.

I have restarted Thunderbird and updated to the latest version, but it made no difference. I have gotten it to work on another computer, but on my mac mini, it doesn't seem to work.

Before I remove the account completely and add it again, is there any way I can fix this as I don't want to download all the messages again?

Is this a known bug in Thunderbird?

If any developer is reading this, In order to reproduce, you would have to follow these steps:

- Setup a Office365 account using the regular password used to login to the O365 website. - When sending the first email, enter the same regular password -> the first time, the dialog to enter the will show up, but it will fail, because the app password wasn't used - Then try to send again, click on "Enter new password" -> no dialog to enter new password is coming up.

I am using Thunderbird 115.10.1 on MacOSX Sonoma 14.1.1

The settings I have used are: server name: outlook.office365.com port: 587 username: my full email address Auth Method: OAuth2 Security: STARTTLS

Thank you for reading this. Looking forward to a reply.

I have just upgraded to 115.9.0(64-bit). Now when I select "Send to email client" I get a message that either there is no default email client or the current client cannot fulfil the request. This did not happen before the upgrade

My e-mail inbox shows a high gigabyte use-age rate, but I only have a few messages in there. I get my messages a couple of times per day and delete emails I don't want to keep. Now it will not get all my new messages as it saying I have run out of disk space. It seems that messages I delete don't really get deleted?? even though they go to trash and I clean the trash folder. I have tried compacting but that didn't work. It seems to be only on my win 10 laptop, as my XP computer is working fine. I have plenty of disk space left on the hard drive. Thanks in advance Bob Parkman

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

I've been using T-Bird for some time now with no problems. Yesterday Xfinity wanted me to change my account password, which I did. This morning I tried to check email and got an error message stating the incoming mail server didn't accept my password - the new one I'm assuming. After several tries I switched it back to the old password which still didn't work. I'm giving T-Bird the Xfinity login password -- is that correct or is there something else that T-Bird is looking for? As a side note -- I just spent 8 days in the hospital and they've got me on a medication that really messes up the higher functions of my brain. I feel as though I'm in a heavy fog and half asleep. Any help would be appreciated... and THANKS~!

Archiving older messages:

I know how to archiving a years worth of messages -- one message at a time, or by selecting a hundred messages at a time IF they are all in the same folder. A painful way to archive dozens of folders full of a years worth of messages.

Why should I be forced to drop into a folder to select the messages? Why not provide a mechanism to archive FOLDER?

I'd really like to select Local Folders (recursive) and hit A to archive -- and be allowed to select Messages older than.

This allows mail to be stored/archived easily by year - and keeps the active Local Folders small and resilient (keeps Thunderbird from being overwhelmed with large folders that seem to bring the app to its knees.

Created several email mailing lists. Stored them in the Personal Address Book (PAB). I'm sorry, but Thunderbird doesn't seem to work like any other email client. How do I address an email using one of those mailing lists in the PAB. Tried typing the whole name of the mailing list in the To: field. Didn't work. I'm not entirely stupid but it doesn't make sense to me.

I checked with my website/email host who show no problem. I was able to see new messages I missed there, so the site is working. I checked with my internet provider, Centurylink (DTTH) who says I'm paid up and there are no restrictions on my account, which shows active. Settings hadn't seemed to have changed, but I received 2 domain emails since then, nothing else. I noticed that the program updated right around the time of the problem, but it comes up and acts normally. 'tis a brain scratcher, it is.

I have created a label library on different computers, but if I add a label other than the standard one on one of the computers, it does not appear on the others. I mean like number 6 Techniczne.

Thunderbird email setup settings don't work with office365 server in godaddy email. Their server wants STARTTLS with port 993. When I select STARTTLS in Thunderbird setup, the port changes automatically to port 143. This I can't connect to godaddy's IMAP mail server using Thunderbird email client. Is there a way to make it happen?

How do i delete 155 emails from the same sender? Or 52 emails from the same sender? Or how do i delete multiple emails from the same sender, but they are not junk and i do not want to inhibit my receiving emails from the sender? Thank you

I found this description of how to use a thunderbird email template online:

Open the template from the Templates folder whenever you want to use it to send a message. Make any additions or changes to the message, and then click the "Send" button to send it. If you don't want to send the message at once, you can select "Save" from the toolbar, and Thunderbird will save the modified message in the Drafts folder, leaving the template unchanged.

The problem is, that when I open a template (right-clicking to open it in a new window), I can't make any changes at all. I can't even delete the dummy recipient and replace it with the one I want. What is missing here? Thank you.
