Somewhere in my version of Thunderbird, there is an old adress of one of my correspondant which is recorded This adress is no longer valid and I have deleted it from my adress book Nonetheless, when I start to write my correspondant's name, this adress keeps being proposed among the first options for the automatic completion of the adress How can I delete this wrong adress from the hidden part where Thunderbird has stored it?

is there any fix about this?

mac calendar keeps wanting me to use a password for Safari, which I do not use, which then passes me on to Chrome. Plus calendar is not syncing with phone anymore. Help

I migrated my Thunderbird installation to a new computer. The installation has 25 email accounts and is now requiring passwords be entered for each account including a couple of gmail accounts.

It was my understanding passwords would be migrated when using the export/import tool within Thunderbird. Is this not so?

Do I now need to change passwords for all email accounts? (because, of course these may have been written down years ago but cannot be located at this time. :-( ) Or, is there some way of restoring the email account passwords?

• • • side note: The migration was not seamless but mostly due to my own ignorance. When using the export/import tool from one Linux machine to another I found the following:

- Thunderbird versions must be the same on both computers - After export, file on USB drive was only accessible by root on new computer - export zip file needed to be copied to user account on new computer (from within root account) and ownership changed to [user]: -R (I imagine you could just change ownership on the USB but this seemed easier)

Suddenly today my address books went from alphabetical to totally random listing. I haven't intentionally changed anything. No idea what triggered this change? Help, please.

Hi there. Have tried everything but still can just receive and cannkt send emails for my personal outlook account that I recently created. Other old outlook accounts are working fine (can receive and send). Basicaly have done everything that sugested here on forum. Please help. Thanks a lot!

I haven't updated Thunderbird since version 52.9.1 because of the interfaces which are painful for me and I don't see much. it still works well but does not support encrypted emails. I would like to install a recent version of TB but how can I make it look like the older, much more configurable versions? Please tell me if this is even possible.

On January 1 my desktop version stopped downloading my GMAIL but my other non gmail are still downloading

I use Windows 10 and the version of Thunderbird is 147.0 64 bit

What can I do to fix this?

I quite often get this message, though it tends not to be a problem later "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

One of the solutions seems to be Compact a File. How do I do this?

I keep getting a certificate error on my Thunderbird. The certificate refers to an email account i no longer have (Personal domain) and i have removed the account in thunderbird, and also removed previous certificate exceptions.

I have been through all menus and settings, and cannot find anywhere where it refers to that domain (and subdomain) I have also removed one entry with that FQDN in the outgoing server section.

What to do?

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

Good day,

I have installed the latest version for win64. Every time the software is downloading emails (I use POP3 for gmail), if I am concurrently doing something else with it (e.g. selecting an email with the right mouse button to delete it, or creating an event for the calendar, or just selecting something from the menu bar), the software gets stuck. I then have to kill it and restart, sometimes it takes multiple kill and restart sequences.

I am using Thunderbird from the very beginning o fit, but this issue is pretty annoying. Any advise?

Thanks and BR M

Have no idea to whom I was chatting a week or so ago, but outlook.office365.com was recommended to me as the incoming server setting for Outlook.com. Set TB that way and used it for a week or so. TODAY got a "failure to authenticate" error from TB (have had many such errors before). Went directly to Copilot, as I thought it would be the most authoritarian place to clear up Microsoft problems. It provided the informaiton below: Official Outlook.com Thunderbird Incoming Server Settings (2026) IMAP (recommended) Settings Server name: imap-mail.outlook.com Port: 993 Security: SSL/TLS Authentication; OAuth2 Username; Your full Outlook.com email address

Why this is the correct server Outlook.com, Hotmail, Live, and MSN accounts do not use outlook.office365.com .

Set outlook account incoming server to imap-mail.outlook.com and reset TB Immediately got: Mozilla Thunderbird Thunderbird Authentication failure while connecting to server imap-mail.outlook.com.

Can someone please tell what's going on?

I have a Fedora laptop which has run Thunderbird on KDE Plasma for years.

I typically put the Thunderbird window on my big monitor where everything works as expected.

When I move the window to the laptop screen (or unplug the laptop and use it without the big screen), I can navigate the folder list in the left-hand pane, but the list of emails and body panes on the right do not display, only the Welcome screen.

When I put Thunderbird in Help > Troublehoot Mode, all works as expected.

The only special add on I use is the Get All Mail button.

I recently updated the computers at my shop. My shop uses an older program Mitchell 1 to process and organize invoices. I have used Thunderbird to email invoice pdfs for the longest time but now after updating I get “ERROR SENDING EMAIL. MAPI RETURNED -2147467259” it’s my understanding MAPI is outdated but I figured Thunderbird would still support this function.
