The latest rev is VERY slow (several seconds) compared to prior revs to process email changes within INBOX (OPEN, MOVE, DELETE, etc.)

Something new is going on internally to the program while the hour-glass appears for a few seconds more than before (I did not change any settings w/ latest upgrades).

How can I change the subject prefix (Re:, Fwd:, etc.) ? I would prefer "RE:" to "Re:" for my outgoing mails. "mailnews.localizedRe" handles recognition of incoming subject prefixes, but I found no pref for my outgoing mails. Thank you!

Hallo, ich habe Windows 11 neu installiert, nun habe ich das Problem, das angeblich mein Mail Passwort nicht stimmt. Ich habe schon alles ausprobiert, die korrekten Passwörter von T-Online eingebeben, die Passwörter geändert, nichts hilft. Ich habe auch schon Thunderbird neu installiert, doch alles ohne Erfolg. Könntet ihr mir bitte weiterhelfen, das ich dieses wundervolle Programm wieder nutzen kann?

Hier noch mein System: i7 6700 K, WIN 11 HOME, GTX 970Grafikkarte, 500 GB SSD, 16 GB RAM, 1 TB Harddisk,

Danke im Voraus

Rainer

I wish to transfer my Thunderbird accounts (i.e. I have two different email addresses in one Thunderbird installation) from my 'old' PC to my 'new' laptop.

Historically I have backed up my emails by copying the Thunderbird folder from <user>/AppData/Roaming/Thunderbird and pasting it to my backup disk. This has worked well for more than 6 years. In that time, I've had to recover a couple of times by simply re-installing Thunderbird, establishing it with my main email account (ian_and_maureen@yahoo.co.uk), then replacing the newly established .../Roaming/Thunderbird folder with the archived one, thus recovering all my subfolder data in the Inbox of ian_and_maureen... plus a second email address.

I've tried to do this with the laptop, but I don't fully recover the historical data, all I get is the current Inboxes for the two accounts with no historical data. Can you advise me what I'm doing wrong? If this is the wrong way, what is the correct way? It seems essentially the same action as is described by the guide found at Moving Thunderbird Data to a New Computer | Thunderbird Help (mozilla.org)

My PC is running Windows 10 Version 22H2 (OS Build 19045.4717) with Thunderbird Version 115.13.0 (32-bit). The Laptop is Windows 11 Version 23H2 (OS Build 22631.3958 with Thunderbird Version 115.13.0 (64-bit)

There are many answers to the question of how to disable message threading. All are from earlier versions than mine, which is 115.7.0 -- as witnessed: Sorry! 0 results found for ‘disable threading in version 115.7.0’ for ‘Thunderbird'

Thunderbird seems to have so many minor changes and alterations in the recent past, that basic usability is affected. Not a good thing.

Once before, a few years ago, Thunderbird got so out of control that I had to go to a different mail client. Are we back to that?

Dear MZLA,

I donated to MZLA, looking forward to an "improved" Thunderbird. I am very frustrated by the result.

Downloaded and started new Thunderbird, and I have several questions:

This is a serious inquiry; I am desperate for information & help.

1. What happened to my address book? How can I get it back? A hundred or more addresses just disappeared.

2. What happened to all of my saved messages? How can I get them back? I used to have a neatly organized file of saved messages. If I was still using Tbird for my business, I would be looking for a lawyer. As it is, I am simply looking for something as useful as the old Tbird.

3. How can I save a message to a specific category or off line file? I used to have several hundred categorized files in my data base for saved messages.

4. Why does my effort to use a help request not respond to my mouse clicks? It seems to always want more donations.

5. Can I go back to the old version? It was easier to use and more straightforward.

6. What am I missing in this "new and improved" version? Is there another email application that would give me the nice features of the old Thunderbird?

7. Can I revert back to the old Tbird and recover the extensive lost addresses and saved messages?

8. If I decide the "new and improved" Tbird will not provide the features the old one did, how can I get a refund of my contribution?

Your early response will be appreciated.

Jon Wilson,

I followed a prompt to compact the data in my Thunderbird email folders. After I did so, I found that the content of all the emails I sent after 4-16-22 was missing. The list of the sent emails was still there but the message box was blank for all those emails. I know who an email was sent to but not what was in the email. This was on my laptop. Surprisingly, these emails did not disappear from Thunderbird on my desktop computer. How can I recapture the sent emails in my laptop?

Hello, I'm new to this Thunderbird I'm using a desktop computer with Win 10 and Office 2016. I have been having issues with outlook 2016, it keep asking for my credentials and I can't seem to be able to find any solutions so a friend recommended Thunderbird to me. I'm trying it and so far my emails are synchronized but not my calendar nor my address book. I cant seem to find where Thunderbird can sync with those two. I do not want to import into the app but sync like my iPhone is doing so if I enter an event in any of them it will show up in the other one. Pretty simple but I can not find this in the Thunderbird desktop app.

please help Kind regards Richard

my husband has been using mozilla thunderbird for a long time. it is easier for him than anyother. today he can't even get it to open up properly. Any help would be great

Microsoft sent me this: Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Will Thunderbird continue to link me to Outlook? If so, how?

Thank you.

I came to Thunderbird because I have been using an email server - btinternet - for many years and it has become clogged with a backlog of emails many of which were not opened and remain so. I would like to retain my email address, John.romm@btinternet.com, it is a vitally important one for my work. But I would ike to use and manage it Thunderbird which is already working well for me. However, it is important to do both of two things. First, I need to bulk delete all unopened emails - some 160,000 of them. And second, I would like to construct filters to keep a wide range of incoming emails out of my inbox. Please help!

Whenever I am sending mail, i am getting below error. Please help me in resolving this.

Sending of the message failed. An error occurred while sending mail.

Does "mailnews.localizedRe" still work? If yes, how?

The (preinstalled) default value is "AW,Aw,aw". But when I reply to a message whose subject line begins with "AW:", Thunderbird prepends it with "Re:", so that after a few back and forths we have silly subjects like "Re: AW: Re: AW: Re: AW: .............. ".

Has "mailnews.localizedRe" stopped working? Or how can I get it to work? Thank you!
