Using TB v91.5.1 on Windows 10 x-64. I have several mail accounts, one of which is for a hotmail.com address. This has been working fine for years, but over the past couple of days, I don't seem to be able to send emails form this account. I can receive them fine, but when I try to send, I get the small pop-up telling me it's sending the message, and the progress bar is at 100%, but it doesn't send the message, it just sits there.

I looked in the error console, but nothing was added when I tried sending.

You can see my server settings for the account in the attached image.

Any ideas? Please let me know if there is any other info you need.

Thanks

I've searched the community and knowledge base, and I am not seeing a solution that works. The video listed below shows the issue but here's a recap: An event I accepted an invite to just completed. The notification popped up before the event as hoped for, but could not be dismissed. It continues to repeat about every 20 to 30 minutes.

Clicking dismiss does nothing. Clicking dismiss all does nothing. https://www.screencast.com/t/NAPTzvp9kOoh

Any help is appreciated.

Hi all

Since yesterday Thunderbird is unable to connect to the server and download new emails.

I got the following error message: "Non-overridable TLS error occurred. Handshake error or probably the TLS version or certificate used by the server mail.blacknight.com is incompatible."

I am running Thunderbird v102.2.2 for 4 days now but yesterday was the first time this error has appeared.

security.tls.version.min is set to 1. In fact, it has been set to 1 for more than a year now.

The host tells me everything is fine with the cert used by their server.

Any ideas or help would be greatly appreciated.

Dear community,

in the past, I have noticed that a few e-mails - but not all - are displayed incorrectly as plain text instead of the usual HTML-text. This means that there is no formatting involved, e.g. the font art is not correct. As it seems, the issue occurs when the standard formatting options of e-mails are used by the senders. So if nothing is changed like the font size or colour. If I look at the e-mail on different e-mail programs, everything is alright. I have already ensured that the option View > Message Body As > Original HTML is enabled.

Thanks in advance for your advice. batengo

I have Thunderbird installed on two computers.

On one of the computers, emails being held in my inbox are being automatically removed after two weeks (this is not a desirable action, I am loosing important emails), but on the other computer that is configured exactly the same, emails remain in the inbox indefinitely (which is desired).

Both computers are POP and both configured to run the same email account and appear to have all of the same configurations and settings. I saw someone had posted the same problem a while ago and the reply indicated it may be that the ISP or email provider has their settings set to delete emails as per the two week window, but as I can assure you this is not the case, it is a configuration issue with one of the Thunderbird installations, otherwise both of my computers would be deleting the emails while that is not the case.

Thanks,

Jeff Rogerson

Thanks.

When Thunderbird updated to 102.6.1 the other day, my address book disappeared. No more personal address book or contact lists. Gone. (My 'Personal Address Book" went from 2,000 names to 24. Yikes!)

Plus, I can't even type people's names into the emails and expect it to populate like before. I have to search for their emails and rewrite it.

Is there a way to fix this? Or to roll the program back to the previous version?

Since I backed my email list up last month, I've made lots of changes. But if I have to, I'll just re-import and try to recreate what I've done. (Reminder to self to back up more often).

Thanks for any help or guidance. PS - I'm on Windows 10.

Hi,

TB 91.5.0 on Windows 10 (with profile folder excluded from virus scan)

The latest update to seems to have resurrected a problem with saving copies of sent emails. Sending works fine, but copying of the sent email to the sent folder causes the send dialog to hang. Disabling the "Place a copy in:" option in account settings eliminates the problem. Using the "Other" option to place it in a local folder works *that is not part of a unified folder* works OK.

I have tried repairing folders and deleting the sent files inside "smart folders" in the profile, with no luck.

Hi Community, i wanted to ask wether it normal that Thunderbird 115 needs 60 seconds to load the interface? When it starts it shows my personalised theme and an empty space for a whole minute. (i measured it)

Directly after installation everything was fine. But now i have set up my acconts and rearranged some buttons. Is there maybe a problem with Exchange synchronisation on startup? Both of my accounts are provided by Exchange servers.

D:\>

I need to log SMTP traffic when I send a piece of mail from Thunderbird. What I see in my pop3.log.moz_log file is SMTP traffic when Thunderbird downloads mail from the server. But I do not see the SMTP traffic when I send a piece of mail to the outbound server. When I look at previous logs, I see SEND records in a log from 2020-03-02. Did something change in the SMTP logging? I am running Thunderbird 91.8.0 64-bit in Windows 10 Professional 21H2 64-bit.

I've been running Tbird on Windows for many years. About 2 weeks ago something changed, either in Tbird or at Microsoft, which stops me from sending to the Office 365 SMTP server. I can send and receive using Outlook on the Office website, but I can't send locally from Tbird. Error message screenshot herewith. I have tried every possible permutation of server settings, which currently are:

Server name: smtp.office365.com Port: 587 Security: START/TLS Authentication: OAuth2

MS support says these are correct, and they are at wits' end to understand what is going on. They asked me to ask Tbird support, so I am.

I should add that at about the same time I started getting SMTP rejections in Gmail on my Android phone, and miraculously that was corrected yesterday, without any action from me. There is something odd going on at Microsoft - does anyone know what it is? My other accounts on Tbird work fine of course.

Hello - I upgraded from TB 78 to 91 a couple weeks ago, and my boss just let me know today that in Outlook, which most of my coworkers use, my digitally signed emails are showing the error "There are problems with the signature" for all of my emails since the upgrade to v91. Specifically digging into the Outlook error shows:

"Error: The message contents may have been altered. Signed by heise@wisc.edu using RSA/SHA256 at 9:15:07 AM 2021-10-22."

I did not change my certificate, and emails sent using Nine (Android email client) and Outlook show up as fine. It's the same problem that this user describes here from several months ago.
