I have latest Thunderbird version (115.9.0 64bit) on fully patched Ubuntu 22.04.4 LTS.

I'm trying to get it to display Day-of-Week for old messages - is this possible? I have tried all sorts of combination as detailed HERE to no avail.

I'd like concise instructions on how to do this (if it can be done). I do not believe trying a new profile will work as I need to test this for old messages - at least for messages older than a week.

From the link above, I can the Day-of-Week to work for the current week - but that only displays the day and time. What I'm after is as shown in the attached Outlook screenshot. Also see the closest I can get that to match in the Thunderbird screenshot.

Hi folks, I am wondering if there is a way to change the behavior of the pop-up reminder window in Calendar. When I have missed reminders (e.g. a task set for today at 8am and it is now 9am), the task is visible in the reminder window that pops up every time a reminder is active. This is fine. But if there is a past reminder (not resolved), every time I add a new task (or edit a past task) to the calendar, the pop-up reminder window opens and comes to the front. Let me describe the example: I missed (knowingly) a reminder at 8AM. Now, at 9 AM I need to add 3 new tasks to the Calendar. After setting (or copying, editing) each new task, the pop-up reminder window is focused on the front. Can I change this behavior so that the reminder window only pop up when the reminder is due and not in the case a new task is set up or old one edited?

Already invested time creating some html code for email signature on thunderbird. Wanted to create something prepared for dark modes on IOS. Everything was fine until I detected on IOS (dark mode)some white rectangles outside my email signature code. It´s a problem that I cannot solve because it´s outside my code, and I´m wondering if you are already aware of this issue.

In case you want to test my code on a Thunderbird HTML email signature and see the result on an iPhone (dar mode), you can get it here: https://codeshare.io/dekBnR

Junk, Bin, Deleted confusion in email account There is confusion in Settings regarding Junk,Spam, Bin,or Deleted. When setting up Spam checks it refers to Junk folder where I have customarily used Spam folder and or Deleted/ Bin folder options which am now not able to set in the options available. Is there any way around this. I use' Ubuntu Linux' and 'Android (Gmail')? Thankyou Walter Reed t.walterreed@gmail.com mail@walter.plus.com

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

Any hint on forwarding step? Thanks Lars Granath

Hello from one of my mails I can`t see the external issues. I gave permission to show all content in the mail, and that was stored in the list permission to show all external content, but still the content is not shown. Can you please help me, and tell me what I can do so I can see all the external issues in the mail.

Thanks and with regards, Henny Noorman

My Thunderbird email on my PC will only open intermittently in the last few days. Re-starting my computer sometimes helps, but only temporarily. There are no error messages- just nothing happens. I am still able to access email on other devices - just not on PC - which I use a lot. I'd be grateful for ideas of how to fix this. Thank you, Pam Rycroft

Will there ever be an option in the calendar to schedule links to video conferencing platforms like zoom or teams or google meet?

Lot's of other 'smart' calendars have this as an option. For example, when I use google calendar on a browser there is a zoom plugin so when I schedule an appointment it automatically generates a meeting invite for the attendees and put the meeting on my zoom app.

I know that this is probably reliant more on the companies [Google, Microsoft, Zoom] to make an extension for this, but it would be great if this could be implemented in the future.

Hello. I have my outlook.com account set up in Thunderbird 115.10.1. When I delete emails in Thunderbird from my inbox, they disappear and they go to the Deleted folder in Thunderbird as they should, but they aren't deleted on the Outlook server. I can still see them in my inbox if I use my Outlook app on my phone. I must delete them using my phone.

If I delete an email on my Outlook app on my phone, they disappear immediately in Thunderbird, which is correct. In other words, it works correctly if I delete from my phone, but not from Thunderbird.

My server settings are: Server Type: IMAP Mail Server Server Name: outlook.office365.com Port: 993 Connection security: SSL/TLS Authentication method: OAuth2 When I delete a message: Move it to this folder: Deleted on <myaccount>@outlook.com

Can anyone help? Thanks!

All of a sudden, over 6 months of my "deleted" items dropped off. I like to keep up to 9 months items for history reference if needed. Is this an automatic thing, or if, can it be adjusted by settings?

I need the option to convert message date to local time on forwarding, instead of UTC + - from the original header.

This is the expected behavior in every other client I have used.

Even if the original sender is in the same city as me, chances are their originating server could be somewhere else and their originating time preference may not be set correctly. So it's more useful and logical to end user to show that in my local time zone.

Please, at least make it a user preference option.

I am not the only one:

Until recently when a spam email was received, I could go to my Message Filters and one set up as DELETE. After entering the spam email address I could then select RUN NOW and the spam email would be deleted. When I click RUN NOW at present nothing happens. How can I get this filter to work again.

(TLDR; Questions in bold at the bottom)

I currently have just a desktop Mac. I recently switched from Apple Mail to Thunderbird to read three email accounts: iCloud, gmail & a university account. I had previously used rules at the server level on my iCloud account, and this caused hella pain during the migration, including some zombie rules that I think I have isolated to Thunderbird. I deleted the rules from iCloud, removed the iCloud account from Thunderbird, restarted and then re-added it to Thunderbird. So far, so good, although I had to resubscribe to the draft, junk and trash folders (all other than the inbox) for some reason.

I have decided to experiment with not using rules or folders at all, and instead use local saved searches in Thunderbird. This will make my life easier when I get a laptop, which is inevitable. Two machines reading the same IMAP emails with rules can get weird.

Can I copy/paste existing saved search folders, so I can do similar searches just by making minor changes to the search terms? If so, how?

Can I copy/paste or save saved search folders, so I can do the same searches on a different Mac, without painstakingly recreating all the search terms? If so, how?

Can I create a saved search folder that contains all the messages not found in any OTHER saved search folder? If so, how?

Yesterday, whenever I tried to open Thunderbird I got a This app will not open on your PC Windows error, and Word and Excel would not work. Apparently I had some Windows 10 problems which I was able to repair with Windows Resource Protection. Thunderbird now runs, but all 2000 of my Inbox messages do not appear. If I open my Mail folder in my Profile, I see the four folders inbound.att.net, inbound.att-1.net, inbound.att-2.net, and inbound.att-3.net The size of each of these inbound Mail folders is 5MB, 9.8GB, 38MB and 20MB. So, all of the missing Inbox emails are in the inbound.att-1.net folder but they don't show up. I tried deleting the .msf file. That didn't help.

Does anyone have any suggestions?

I prefer to see only new messages in my Inbox. To that end, I've chosen the icon that says "Show only unread messages;" but it will not stay chosen. Every time I leave TB and come back I have to chose the icon again or see all the messages I've seen and reacted to before.

Is there a way to make the choice to see only unread messages and have it stay in use?

I was able to change the color of the context menu (the menu you get when you either right click or click on a dropdown) and the color of the highlight/selection as shown in the attached screenshot.

The default color looks like it's black, and I'd like to change it to match the rest of my Arc-Dark gtk theme. Does anyone know the name of the CSS tag that controls the context menu border?

Here's what I have so far:

/* Context Menu */ menupopup > menu, menupopup > menuitem,popup > menu, popup > menuitem {background-color: #404552 !important;}

menuitem:hover, .menu-iconic:hover, .menuitem-iconic:hover {

border-radius: 0px !important;
background-color: #5294E2 !important;

}
