I just recently switched to Thunderbird and Libre Office to get rid of MS365. I am happy so far, if there wasn't one particular issue which I do not find a solution for:

I know how to sort messages with the newest on top, I know how to toggle the threaded view on and off. But I would like to use the threaded view and find it impossible to adjust a descending order within a thread. So I end up with the newest thread on top, but the thread headline shows the oldest message and if I unfold the thread it's in ascending order.

This is a major issue for me. To avoid overlooking incoming mails, I need to switch of the threaded view. Websearch didn't provide me a solution.

Sending a mail results in the following message:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Disallowed HELO string.

Hello TBird fans,

I wonder when ThunderBird native client for Android (currently named "K-9") will evolve to a point when internal calendar syncing will work properly, eliminating the need to import google calendars into desktop Tbird ? Is it possible to estimate that time now, or it's better to search for alternative solution(s) ?

I will need an Android synced calendar app soon, I would prefer ThunderBird, since I've been using it for at least a decade, and I'm not even satisfied but became enthusiast also. Best email client ever made IMHO. It would be very convenient to use TBird's integrated calendar.

I've searched the forums for "android calendar sync", but didn't find corresponding info, just this archived thread is closest to my question (particularly the 3. question of it) : https://support.mozilla.org/en-US/questions/1436077

I'm not willing to use google calendar, since I don't want unstoppable notifications and ads when my events are due in time.

Thanks, Peter ;-)

Using Tbird 115 (or later) can gmail contacts be the listing used in Tbird and be in synch when changes are made in the gmail contacts list. There appear to be various methods and I seek the best and simplest. Thanks

I use Thunderbird on Windows 10; I have a verizon.net email account which I access through Thunderbird. Verizon.net email is transferred to the server from AOL Mail, and I have been able to get and send my emails on Thunderbird at verizon.net for years. This week, after Thunderbird's latest update, I have not received any incoming mail on Thunderbird, but I can see my emails on AOL Mail. The technical expert I consulted deduced that the problem is with Thunderbird such that AOL is not connecting to the incoming mail server, even after the password was changed. I can send messages successfully from Thunderbird; the outgoing mail works.

I just updated to V128 (from 78) and I had a bunch of custom named in added to mu dictionary.

I still have the old version on mu computer, how can I either export from the old version and import to the new version, or, can I simply copy over my custom dictionary to my new profile somehow?

Thanks, Mark.

New up date Thunderbird 115.13.0 (64-bit) has completely removed all my local folders and my address book this is devastating with a complete loss of all this information is there a way of getting this back. I have used Thunderbird for many years and trusted it completely have never had any problem please help my system is Linux mint Linux Mint 21.3

My inbox messages that are incoming are showing the following message and no data. This has happened for several days. It comes from both internal and external contacts and I know the emails are not spam/junk. How do I fix it so I get the messages. It is this same code on all days and all the emails with this message. I do get some of my other emails so not sure how it is decided which this is happening to but I am missing out on several that I need due to this issue. Thanks for your assistance!

I successfully changed the authentication method for my SMTP server to OAuth.

But when I try to set my IMAP server to OAuth, I get this error message:

The IMAP server imap-mail.outlook.com does not support the selected authentication method. Image attached. Note: I couldn't capture the whole image, as Firefox insisted on displaying the error message at the bottom of the screen where I could only see half of it. But I confirmed OAuth was the issue by changing it back & forth several times.

I thought we had to change both SMTP & IMAP. Did I misunderstand something?

Some of my searches show emails that were in folders I deleted a long time ago. When I click 'Show results as list', it's empty (which is what I expect). How do I keep Thunderbird from showing the emails in deleted folders in the results I get?

My Thunderbird just updated itself to 128.2.0esr, and now every time new mail arrives it plays a sound even though "Play a sound" is not checked in settings. I tried enabling the setting and then disabling it again, but to no avail.

Help!

In the Thunderbird calendar, I'm trying to create a repeating event that occurs on the fourth Wednesday from Sep 25, 2024 through Jan 22, 2025.

But each time I try to set it up, using Jan 22 as the end date, Thunderbird changes the end date to Jan 21 and so the last event does not get created. I've tried several times and this keeps happening.

What's going on?

I have used MailStore Home to archive then export an Outlook PST file into Thunderbird. The Export appears to have worked, but I notice that the resulting file structure in Thunderbird Local Folders has "MailStore Export / Outlook Outlook Data File / Inbox", with all my folders residing under the inbox folder (which they should). Is there a way I can change the Local Folder structure to remove the top level "MailStore Export / Outlook Outlook Data File" and leave the top level as "Inbox"? See image.

Since yesterday, I suddenly cannot receive mail from the office365 server with thunderbird. Authentication passes, but timeout occurs when receiving mail. There is no problem with sending mails. I did not change anything in thunderbird settings yesterday.

[setting] Server Type: POP Server name: outlook.office365.com Port: 995 Connection Protection: SSL/TLS Authentication method: OAuth2

Dear All,

I think that is a compability problem of Citadel with Thunderbird email client.

After several steps to try to solve the problem I found that Citadel is not compatible with the last version of Thunderbird.

I tried Linux (Centos 9) and Windows Thunderbird. I tried my affiliation network and with my mobile hotspot.

I can send emails with my Android email client.

I am thinking to make a downgrade of Thunderbird. I have there all my emails from always.

But first I have to backup everything of Thunderbird. Time consuming task.

Some help is needed.

Microsoft are again complaining about normal password login.

Today I have updated to Version 128.2.0esr (64-bit)

I have set outgoing server to StartTLS and OAuth2 and it is fine.

When i set OAuth2 in server settings and try to retrieve mail i get "Host contacted, sending login............" and it sticks at that point with no error messages from Thunderbird or Microsoft.

If i revert to "Normal Password" it is fine.

When microsoft first complained i turned on two step authorisation and the used their option (cannot remember what it was called now) to create a login password/key for thunderbird so that it would still work for "Normal Password" setting

How do we get round Microsoft's obstacles???>

As a Thunderbird user and supporter, I have never had this current problem. I have two PC's this one running windows 11 version 128.2.0 (64 bit)and the other running Linux Mint. However the version on Linux is 115.13.0 (64 bit), and does not have the issue. Both pc's have one add-on for google email, calendar, and contacts. to stay in sync. In trouble shooting I have disabled the extension's.

Before the update to 128.2.0 I could scroll back a month and open any email coming to me. However in this version I can only go back 6 days of messages. The 7th day and older will not open. On my Linux Mint system with 115.13.0, I can go back years and open any message.

Is there a new setting that changed all this? I was under the impression all messages were saved to my local drive and not pulled off the Google server. 73's Ed

Hi, after an update, i have the newest version of Thunderbird installed. Upon starting, it says: "Unable to use profile when you launch an older version of Thunderbird." I cannot start the program. But it is the newest version... What can I do? Thanks Lukas

Hello, I have spent considerable time scouring help forums, but still unable to resolve. I am running Windows 10 that is fully patched, and most recent version of Thunderbird.

In my recent attempt to setup gmail; - I used Chrome as default browser with default security settings - I turned off 2fa in Google - I turned off VPN - I left gmail password blank during account setup in TB - authentication initially fails during setup, so I then select manual config and normal password. This allows TB to supposedly complete gmail account setup successfully. - browser opens up requesting TB access to gmail, (Allowed Apps in Google include TB) - I change gmail server settings to Oauth2 and restart TB - The saved passwords in TB only list an Oauth2 pwd for calendar, but no entry for email.

How do I get TB to request and store credential for imap.gmail.com?

Thank you for your help, Jeff

Since the latest update 128.2.0 I am getting message "The certificate for pop3.go-plus.net is not valid for that server. Someone could be trying to impersonate the server and you should not continue." when I try to receive emails. Everything worked fine up until today, even though I had to click an "Certificate Exemption" box after re-starting. How can I get to receive emails? They appear to send ok.
