Thunderbird Support Forum

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

Ever since the Cox-Yahoo migration I am finally getting emails in TB (few glitches). but emails/changes take several minutes to appear/update on my iPhone . My iPhone only option is for Fetch and the time is 15 Minutes..so I have to open the MAIL app and it will look for new/updated messages but it takes a good 2-3 MINUTES to appear. And if I delete a message on TB sometimes it never updates..any suggestions?

We've just started having an issue with Thunderbird continually prompting for Calendar passwords, but not remembering them. IMAP and SMTP seem to be retained ok. Additionally, if we just skip past the prompts (we are using around 5 different calendars), and just go and click the "Enable" button....they open just fine and we don't get any prompts, until we close and re-open Thunderbird. We're running 115.12.1 on Windows 10, 11 and Server 2022 Datacenter. It's not a devastating problem, but a little tedious for some of our users that open and close their Thunderbird a lot during the day. We are running "Smartermail" V8909 from Smarter Tools as our mail server. Thanks in advance!

Trying to update to the 115.12.1 I am getting the message "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you wan t to reboot now?

If I select no nothing happens if I select yes then the computer reboots but no changes are made

I am not able to access my emails or upgrade Thunderbird

Please advise

I have a problem with Thunderbird 115.11.1 with the POP3 server inbound.att.net. Someone on at at7t forum suggested changing from Userid/password to Secure Mail Key. I had previously set up two Keys with at&t, but AI have never activated them. I looked at one URL, and was able to change the settings for inbound.att.net. But I did not see anywhere to enter one of the Keys that I had generated earlier. When I tried to re-configure outbound.att.net, I did not see a OAuth2 option. I do not need to re-configure outbound at the present time, as I can send mail without a problem. But receiving mail does not work. Here is what I see in the error console log:

Here is what I changed: Thunderbird: Account Settings --> Server Setings --> Security Settings --> Authentication Method Normal Pasword -> OAuth2

                                                   Inbound.att.net: Port 995 --> 587
                                                   Connection Security: SSL/TLS --> STARTTLS 
   

What do I have to do to get one of my two Keys into the inbound Thunderbird configuration? Thanks.

When I select "Sent" emails to review to see what I have sent. I find that Thunderbird will not show emails with attached files. (see image) To see what I have sent with attachments I have to select attachments. (see image)

I would think that I should see ALL the emails sent when first selecting "Sent".

I then should be able to view only sent emails with attachments when I select attachments.

Are my settings off or is this a bug in the software?

Let me know. TY

Can't use Gmail account anymore have cleared cookie's and caches removed permissions and account from Google and TB uninstalled then reinstalled then add TB account worked for 2 minutes then got the same error also some emails load while others are just a blank screen all windows 10 and TB updates are current Have attached error we are receiving anything else please just ask Any help appreciated

Hello,

I updated to 115.11.1 (32-bit) and unified folders will not appear and the option will not stay checked. I have exhausted my options. I previously had 64-bit with same issue so I deleted and installed 32-bit as some said this would help the issue ( I'm on 64-bit windows 10 OS).

I've tried deleting smart mailboxes, virtualfolder and jsontreefolder

nothing is working, I am at wits end. Please help!

Starting 3 days ago: Cannot SEND email - receiving works fine. Error message: An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The other odd thing is that I get asked for a password before sending which never happened before.

I followed advice given someone in 2022 - I've messed with the account settings (unfortunately) and I've changed the SMTP settings to match what Comcast recommends.

I have 3 comcast accounts; two work fine on my iPad and iPhone - one doesn't

Also I have no problem sending emails using Xfinity/Comcast Mail... but I want to use Thunderbird.

Where do I start looking?

Thanks!!

I'm sure I've made the problem worse by trying to change the setup

I'm connecting to an MS Exchange server via smtp.office365.com and mostly this works OK by now. I do have a stupid problem, however: After deleting several folders, they always "come back" as "ghost folders" (grayed out and without messages) and it's impossible for me to get rid of them. Very annoying. I've tried a couple of steps:

• of course, I tried deleting the folders through the Thunderbird interface, also from Trash, where they first move to
• I also tried to delete msf-files associated with the deleted folders -- to no avail
• I also tried to unsubscribe from these folders using the "Subscribe" interface -- this is not possible: I can tick off the folders, save my choices, but as soon as I open "Subscribe" again, these folders are back
• I also tried to use Outlook, but the deleted folders are not shown in Outlook -- it seems to me that Thunderbird has difficulties letting them go

I'd be very thankful for any constructive help!

When I receive junk email, Thunderbird shows mail received (for example 10 emails) there are ...again for example 3 in my inbox and the other 7 are nowhere to be found. Not in junk and not in trash. I am concerned that there might be some emails that are not junk that I am not able to get. I would like to be able to review the junk folder prior to deletion. What setting options do I need to change to make this happen? I am using pop email... Thanks!!

Hello! I have linked my smartphone with the add-on: Provider for Google Calendar. How can I now transfer my existing appointments to the Google Calendar? I tried to export the existing appointments and then to import it into Google Calendar. Unfortunately, this was not possible because not a single appointment from the existing calendar is exported. I just get an empty .ics file. Any help? Please! Martin

I want that all my mail from all mine email boxes be restored to the original mail boxes. Now all the mail is removed there and that must not be done

How do I copy it back!!!!!

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

I use the global search a lot (when it works!) I don't like the way the results are displayed so I always click 'show results as list'. Is there a way to make that the default way search results are displayed? thanks

I have not been receiving replies to adds I have on Gumtree, to my primary email address, denisj51@msn.com. Gumtree has advised me that my email client, which is Thunderbird, is identifying them as Spam, and is deleting them! I check the junk folder of that account regularly, and they are not sent to that folder. I would like to stop them being deleted. How do I do that ? Thanks for your help. Denis.

Do I install the 64bit option or 32bit ?? The installer gives me a choice.

After installation on the new M3 mac, I will be migrating my Thunderbird profile from a 2021 iMac that runs BigSur on Intel silicon.

I'm anticipating updating the iMac to Sonoma, but long experience has shown me that major s/w version upgrades are often very unfriendly to 3rd party s/w apps&data, so I wanted to get my tBird profile (all my mail history) working on the new Mac before doing the major upgrade on my iMac.
