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.

Hello, I would be grateful for help onm the two following problems in Thunderbird. 1. When someone sends me a web page link, I click on it and get the error message 0x80070057. I have tried the suggested solutions in regedit but it does not work. 2. When I buy something on ebay they send me an email confirmation with a picture of the item purchased. When I go to print it the image disappears.

I am losing what hair that I have left as I am a senior citizen.

many thanks in anticipation. kr David

Within last 2 to 3 weeks I noticed that when I click Get Messages the momentary line of text at bottom-left typically says "there are no new messages", or the "number of messages" about to be downloaded. (This is not the notification window at lower right.) Recently the number of messages actually received is not always correct. For instance, this morning the message was clearly "downloading messages 3 of 3", but only one appeared as a new, unread message in my inbox. This has occurred several times, sometimes qty is correct, sometimes not. My first question is whether this is a bug in Thunderbird, or something I need to pursue with my email provider? Second question: I am only requesting those for my account, but might the "missing messages" be downloaded for my wife's email?

If missing messages are for my wife how do I fix it so I only download mine? She doesn't have admin rights and I made no changes to our account settings. If missing messages are not hers then I am seriously concerned about this issue.
