I have been using Thunderbird calendar synced to gmail a/c on Linux Mint for many years and have been able to send reminder notifications by email. Recently I had to unsubscribe my calendar and reinstall to clear a fault and the notification by email function has disappeared from Thunderbird event notifications. Can you tell me how to restore that function?

Version 140.11.1esr

Hello, I use Thunderbird to manage several email accounts, one on them is not active anymore but I still want to be able to access the emails stored in my thunderbird directory tree, so I keep it active. And the fact is that every day this account tries to access a remote server that does not exists anymore to retrieve email that can not be retrieve, and every day I am asked for a password that cannot work. But the fact is that I did deactivate all options to read remote emails for this account, so that behavior is odd and I am not able to find a way around it. Any idea what to do not to be bother anymore ?

Thanks in advance for your help :-)

After upgrading from Mint 21.3 to 22.3, Thunderbird no longer offers me the option of setting email alerts for events. Details: - I have Provider for Google Calendar installed - I've tried adding my calendar as "Google calendar" and "On the network" but neither offers email alerts. (On the network works better for responding to invitations.) My current work-around is to go to the google calendar app on my phone and set an email alert after creating the event in Thunderbird. That works but is a pain. This worked before. I suspect it's more a configuration issue and less a Mint version issue.

End user here, with Thunderbird for years, now on several machines that I use. Keep getting the warning window about "ESR" change. I have no wish to re-install Thunderbird, on each machine, nor to go beyond the normal updates. Can't tell which "channel" I need to choose. Unwilling to just guess. Could re-install on all five machines, if that's truly necessary. Hope not. An explanation of the simplest way to dispose of this issue, is the help I'm looking for. I think I'm currently set to the lower case address. And arranged such that each machine updates to the current content.

IIRC, there was a discussion some time ago that a repository for .deb packages would be made, similar with we already have for Firefox. There was any development in this question?

My Message Source displays text in very large Liberation Mono. I can't find a setting anywhere, including Advanced Preferences. Where can I change that?

Liberation Mono is the font I have set for monospace in different languages. Since it is not the default, there may be a connection there.

Also, since yesterday when I reply to certain HTML messages, the font used for quoted text is again large size Liberation Mono. I haven't changed anything, so I suspect it's a bug in new 152.0.1.

At the beginning I see some message disappear (moved from inbox to the folder but never show in the folder) then following some advises I made a Repair Folder, then all messages in the folder disappear.

As you can see, on the gmail picture there is 114 emails in this folder, in the Thunderbird picture it count only 7 and display none.

Please any one have a solution ?

I'm working with Thunderbird 152.0 on linux (Manjaro GNOME). I've been having this issue where sometimes while composing a reply, the quoted text of the email I'm replying to in the body of my current reply will be displayed as black on the dark background. It's very annoying when I need to look at specific text to refer to in my message.

Some more observations: - This is not a new issue, it's been happening for quite a while now, possibly years, but it's finally gotten to a point where I want to fix it. - It does not always happen. I suspect it's when the original message I'm replying to has been formatted in html first, whereas I prefer plain text replies.

I've attached an image of what it can look like on my end, as well as one where I select the text to show the contents.

Is there anything that can be done about it?

Thunderbird 140.7.1 i have a subfolder called "purchases" which I add to on a regular basis. Suddenly no messages appear after May 2014 I have logged in directly to the mail server, and all the missing messages are definitely on the server. I have checked the local filters, none are set. I have tried properties/repair. I have tried removing ~/.thunderbird/xxx/ImapMail/mail.myserver.com.au/INBOX.sbd/purchases.msf

Could it be a problem with dovecot indexing on the server? all the other subfolders seem to work fine. It's just this one.

I created a user profile for IMAP and all was OK....Until I deleted the profile for POP and I lost all e-mail folders that I didn't move to IMAP. My PC is running Linux Mint. How do I get my lost e-mails?

Let me explain there is some one with the following email:

noreply@redcarpetradar.robly.com

Whatever anyone does do NOT click on their links I believe it's a criminal organization trying to get to my account.

I know many of you may not be in my situation but I'm a bit job hungry cause financial hit really hard. I clicked on link without looking and the site pretended I needed to fill a job application out. So I did without looking to see who sent it. Yes, STUPID me.

For some reason I marked as junk and it's not going to where I need to and that is trash and immediately delete it. I try and see if I can setup a rule for that. But wondering if there a extension that might do a better job. I tried to unsubscribe but these guys keep hitting back. That one sign of hackers trying to penetrate.

So now I'm wondering is there anything else I might be over looking. One think I keep thinking about is why NOT put something a tool that will do similar to mxtoolbox. With AI out there it's going to get harder to keep these criminals out of our inboxes.

I appreciate any feedback.

Is there a way to make Thunderbird check the server Junk folder when I open the Thunderbird Junk folder? When I empty my Junk folder, sometimes it will find there are more on the server and delete those too, so I never get to see them. Thanks

Hi, a long-time Thunderbird user here using 140.11.1esr (64-bit) Thunderbird for Linux Mintmint-001 - 1.0 with e-mail set up as IMAP for a hotmail.com e-mail.

I'm having (and always have tbh) had problems with saving only one copy of "Sent" e-mails and it's driving me scatty. In "Thunderbird setup" for my hotmail.com account, I always de-select "When sending messages, automatically Place a copy in "Sent" folder" as I know my Hotmail account does that and then Thunderbird will pick that up to store locally as part of the IMAP syncing. I get, as expected, only one "Saved" copy which is fine.

Then, for no apparent reason, I suddenly start to get duplicates even though the "de-select" is still there in Thunderbird setup for the account. The cure seems to be to select it as if I want 2 copies and send myself a test e-mail, then de-select it again so I only get one at which point I only get one copy again. It then works fine for weeks (or months!!!) then, bang, 2 copies start appearing again with nothing (seemingly) changed.

I also have a gmail.com account set up as IMAP which never changes - I've always only ever got one "Sent" copy as expected. Clearly, this points to some sort of weird Thunderbird/Hotmail config issue which is odd as the "mechanics" of Thunderbirds internal handling of copies should not be affected by the remote e-mail and yet the issue is with hotmail.com but never with gmail.com accounts. As a Comms/Radar engineer it's really got me!

Anyone else seen this and, if so, are you able to tell me what's up? What am I doing wrong? It's very odd. Cheers!
