Thunderbird Support Forum

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.

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?

My sent messages are not being saved-error message says current command did not succeed. The mail server for plvltodd@cox.net responded TRYCREATE mailbox doesn't exist Sent .001 + .000secs

Sadly I had to thoroughly uninstall Thunderbird, reinstall and create new mailboxes due to some strange reason. In the past, the inbox would show the email list and, if clicked, a message would show up below a separator line. Now only the list shows up and I have to double click to read it which opens a new window. What a pain!

And yes, I know I can view the message page using F8 but it is on the right side and shorten the other windows.

Is there a way to go back to the view option I had in previously?

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 have been using 4 email accounts with TB for years now with no problems - 2 use IMAP gmail accounts and two POP mail accounts. In the last week, when I open TB (on a mac OS10.15.7) I am asked to enter the password for these two accounts. I have not changed the passwords for these two accounts anywhere else so I don't know why TB suddenly wants me to enter them. No matter what password I enter here, I am told the login failed and am asked to enter a new password. I enter a new password and go back to being asked for passwords again.

What password is TB looking for? Where is it stored so that I can look for it? When I go to Settings/Privacy and security/Saved passwords only passwords for the two gmail accounts are shown. Where can I find the passwords for the POP Mail Server and how do I reset them?

I'm using thunderbird 115.10.1 on Ubuntu Linux. I've set up a second calendar and associated it with an email account hosted by Polaris Mail. That email address has worked fine within thunderbird for everything else for a long time, but I only recently associated it with a calendar. When I get a meeting invite, for example from a gmail user, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. I have another email account and calendar and meeting acceptances and responses seem to work fine.

I've looked at all the settings I can find and they seem appropriate and analogous to those with the working email/calendar. The correct email address appears in the calendar properties opened by right-clicking on the Calendar and selecting properties.

Any help? Thanks.

I know where my emails for my three accounts are, but can't see them in Thunderbird anymore since downloading some gmails. Also my Thunderbird user interface changed some months ago and doesn't look like what I see online in instructions for doing things.

When I search with TB it is not finding all the results.

This is especially frustrating because the main reason I started using TB is because the search on my host's webmail is abysmal. But it turns out that TB search (for me) is even more abysmal.

I am sure this is happening because something is wrong but I don't know how to go about fixing it. I have already rebuilt the global database but that did not fix it. However, the new global database file is about half the size it was before I rebuilt it.

Is there anything else I can do?

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.

Hi,

I have a user who sends me an email to one of my email addresses and it always ends up in the Junk folder. I've repeatedly marked his emails as not junk but that doesn't seem to change anything.

Is there anything I can look at that will help me figure out why it happens, and hopefully find a way to fix it.

I'm on Betterbird in case that matters. I looked thru the release notes and there seems to be nothing tagged with the junk filter.

I noticed this in the X-Proofpoint-Spam-Details email headers: mlxlogscore=764 clxscore=1015

This person seems to be the only person that has this information in their headers. Is it added by the junk filter? Or is it something on the sender's side (he uses an icloud.com and a me.com address)?

Thanks,

Hello,

I'm with All nation security services inc, we use thunderbird to access our emails and for some reason we aren't able to send emails, we get a 550 error message. We need assistance with this, since this is what we use for all our staff to properly get our work done and respond to our client's and employees.

I recently had to change my email address to a gmail account. I want to continue to use Tb but don't want copies kept on the Gmail account. Is there a way to delete the messages in Gmail without deleting them in Tb.

My Thunderbird email program stopped receiving and sending my emails approximately 2-3 days ago.

My email server is ATT. I have spoken to them today for hours and my Thunderbird email is still not working. They forced me to update my ATT password and my email is working elsewhere (like on Yahoo mail). But its not working on my Thunderbird.

ATT provided me updated information (IMAP and SMTP) info that I changed. But still not working.

I recall this occurring 6 years ago and ATT had me to enter a 12 digit code for my Thunderbird password. It was funky but it worked. It was not my ATT password, but hey, it worked. Now having the same problem.

I'm pretty sure I've messed up this info trying to correct it. No idea how to get it going again. Can you help?
