Cannot add Outlook acct. Found settings automatically - OK. Error: cannot authenticate. Addy has 3 "-" between 3 words - possibly problem Two other Outlook's fine Tried Windows 10 & 11 boxes both fail. Manual config fails. Tried smtp with "." and "-" before "office365.com"

I have 3 computers. Two are running Windows, and one is running Linux. I was pleasantly surprised to find that Linux Mint has Thunderbird built in. I keep the two Windows computers in sync with a file compare program, "Beyond Compare" Are my local folders compatible between the two operating systems so I can sync my Linux Thunderbird local folders with the ones I have stored in Windows Thunderbird local files?

Are txt files stored the same in both NTFS and ext4 systems?

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

Please see attached image of the problem.

I have tried looking on Google for ideas but have not found anything on this or how to fix. Hope someone can please help would be amazing!

400. That's an error

The server cannot process the request because it is malformed. It should be retied. That's all we know.

Has anyone had issues with Thunderbird sending and receiving email? I can only send or receive when my wifi is turned off on my phone.

I've tried deleting the app and resetting all network settings on my Android phone but still no joy.

Whenever I use Thunderbird (TB) I get the following error message:Thunderbird is damaged and can't be reopened." This file was downloaded on an unknown date. What is the problem and how can I get rid of the error message.

Salve, Rispondo alle precedenti in merito ai problemi di connessione e quindi di configurazione di un account gmail sul vs client. Dalle vs risposte pare non ci sia soluzione. Se è così è un peccato dopo anni di ottimo funzionamento, sarò costretto a cambiare client.

I wanted a new email address so since I've been using firefox for decades. I wanted to try thunderbird. (i tried mailfence it didn't work at all) So i download thunderbird desktop. It doesn't tell me what it is. Although I've used computers for 50 years, I need explanations for new stuff. Your habit of assuming all is obvious and no explanations needed is so annoying and wastes so much time. Thunderbird says includes powerful email. Then it says email not available . go on waitlist. I put in my name. Then it talks about some pro ( thunder email?) that must be paid. None of this makes sense to me Can I or can I not get a new email? Please answer this note so my questions can be answered.

T-Bird is Freezing (Hang?) from start to freeze was 5 minutes and a few seconds. Have turned off hardware acceleration and now it freezes at just under 5 minutes. Have put on updates. Currently 153.0.1esr (64-bit). I have captured profile, and re-installed and picked up the profile. Still freezes. Turned off AV. Still freezes. I have compressed and "repaired" all folders. Still Freezes. I forced folders to get rid of anything older than 30 days. Still freezes.

I have been running the task manager, and T-Bird in frozen state is only using 4.3% of CPU at most. I do not see any slowdowns for any other program. So this is not a CPU constrained problem. And it certainly is not memory constrained.

All this started within the past month and I think it was after I put on an ESR update (don't remember which one).

I can kill T-Bird and start it and it will get mail if any, and will function for about 5 minutes and then freezes (or hangs). The system is set to fetch mail on start up and then every 27 minutes. I am not using Account hub (and don't know what it does).

One oddity -- This is a W11 Home system, and Mozilla keeps saying it is a W10 system. Could this be the problem? Wife is running a lesser laptop. It is also running T-Bird, but her O/S is a W11 Pro and she is not having this problem.

Thunderbird just updated and the next time I opened it all of the folders I created and the emails I'm storing within them are missing. I found my profile as directed. I'm not sure if I have a backup of it. I've included the screenshot as you ask for. I know that those folders and emails are there as I was playing around with the the 3 lines > View and when I moved between the different choices I saw my folders/emails are all in there.

Any assistance you can provide is appreciated!

Why is Thunderbird consatntly coming up with "Authentification failure while trying to connect to server outlook.office365.com"? It never used to and would download my hotmail emails perfectly until about a month ago. This is very frustrating, I have removed my hotmail account from thunderbird and re installed it, works for ocassionally the back to same old message authentification failure. What is going on with thunderbird?153.02

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

On T-Bird start up I'm given a list of (originally) four Profiles. Currently I only use Profile Three, but on start=up today it is not there. Doing the usual searches does not list it, only 'default', 'new user' and 'profile two'. Is there any way to recover it?
