Thunderbird Support Forum

When I activate a quick filter (like "Show only unread"), a count of the number of messages is added to the right end of the filter bar. This means all the buttons move to the left, so I have to move the cursor toggle it off again. This is incredibly annoying and unintuitive.

Is there a way to modify this behavior so that toggle buttons don't move when they're pressed?

Collecting mail one day, I received a Thunderbird message 'compact now'. After the compact process, some mailboxes are missing. How do I re-instate these deleted mailboxes?

Hello. I'm curious if Thunderbird supports GReader or Fever API for connecting to external aggregator like FreshRSS or TT-RSS?

Examples of RSS Readers that support this are Newsflash, RSSGuard, so I'm curious if Thunderbird supports being just a rss client for an external rss aggregator?

Reason being - I read RSS on multiple devices, plus I keep my Thunderbird closed most times. I only open it when I want to read email or rss news. So I noticed that it sometimes misses some rss feeds when my laptop is closed (this is normal - more news get published while I'm not parsing them). That's why I have an external aggregator collect it and keep it all for me and I just access it with my other devices.

Can thunderbird do this? Thanks

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:

For the last week, Thunderbird hasn't downloaded the mails from my Strato account. I can still send mails, and read the mails when I log in to Strato. Thunderbird still downloads the mails from my other accounts. It worked fine until now, so I suspect the problem is related either to an automatic Thunderbird update or an automatic Windows (10) update.

After updating Thunderbird to 115.5.2 I receive an error when I check (get) messages of my gmail account : 'The STAT command did not succeed. Error getting message number and size......'. However, the messages do come in and so the error turns out false. since the authorization (OAUTH2) credentials are accepted.

I have my server settings check messages from startup; every 5min; automatically download new messages. That works fine. Again only when I goto "Get Messages" the error shows up.

What is wrong here and ho do I fix this? Thank you

I am running Thunderbird 115.10.1 on an up-to-date Windows 11 machine. I have 2 email accounts (VirginMedia and Gmai)l. When I look at the drop-down list from the top-level folders on these accounts the VirginMedia account does not offer "New Folder", but the Gmail account does. I can create new folders via the VirginMedia webmail, but not via Thunderbird. This is a problem which I have had for some months, coping with it by resorting to webmail.

Hello, All

I need major help, please.

I am getting the attached messages when trying to send an email. Thunderbird worked perfectly yesterday morning, but then would not send any emails. I get emails, but cannot send from my 2 accounts.

I am on the latest version of Thunderbird, Supernova 115.10.1

Also, I cannot find out where to change my password for the accounts, because at times I need to fill in a password. I can't find it.

Thanks in advance for any help.

Best, Leslie

I am having older Thunderbird 102.13.1 and when i input into a search field for example: 37.19.223. or "37.19.223." or "37\.19\.223\." it always stupidly and uselessly output tons of messages that contains unrelated IPs:

([76.223.177. [10.223.144.96]

highlighting number 223 as if i have searched just for this number 223

I think that it is reasonable to expect from TB to output only search results where email contains 37.19.223. without any hack, escaping or regex or whatever (if you know a workaround, please kindly share it).

Maybe newer TB works better? Anyone tried? If it works same way, can you please kindly ask developers to fix this?

Here's the technical details: Win 10 Home 22H2 Build 19045.4291, Mozilla TB Thunderbird Version 78.4.0 Build ID 20201019003438 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828

This AM I was able to check / get e-mail five (5) or more times. Then clicking 'Get Mail' displays; connecting to mail.duo-county.com After 15-20 seconds connection to server mail.duo-county.com; Timed Out

I know of NO changes to any setting. When our e-mail was set up, we were told to set we were told to use Pop-3. Our ISP, who does NOT use NOR 'know' TB said we should be using IMAP, could NOT help review nor doing anything without risking ALL folders - files-data!

PLEASE help ASAP. Since we can't get - check mail I'm LOST! My spouse's e-mail is wpj@duo-county.com

Dear all, is there an option to have Thunderbird sync network calendars once upon start? I have a couple of large network calendars and repetitive syncing causes performance problems, but on the other hand, if I set sync to Manual, Thurderbird does not sync upon start and shows only the events that had been cached locally (off-line) in the past, but not any events meanwhile added to the network calendar by other clients. Thus, I either have to remember to manually sync once every calendar after each program start, or I have to activet syncing every xx minutes, which causes the programm to periodically freeze for some time (during syncing). Is there any good solution to this? Is there maybe an option in the config editor "sync upon start"? Thank you very much.

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

I added a CalDav calendar to Thunderbird that is hosted on a Nextcloud instance. While the calendar view looks decent, the tasks view is completely bloated with old, already completed tasks, some even from 2023. I selected "open tasks" or "current tasks" (? German translation) from the menu on the left side. It's not that all of the tasks are misclassified: When I go to completed tasks, there are hundreds of (correctly) completed tasks listed, but still.

Furthermore, the sub tasks of a main task are not grouped. Is this a known limitation or am I missing some configuration?

In general, as of now, the task view is pretty unusable for me. Anything that I can do to help debugging this?

I received the new version, Version 115.10.1, and the next morning I have emails going to other folders, 1261 junk files that had already been received over maybe the past week or so all received again AND not filtered to the junk folder but rather to the inbox. 2 emails moved from inbox to another folder. Train wreck.

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

Question: How I can access shared folders in Thunderbird?

Office 365 business. I can access admin portal etc:

portal.office.com/adminportal

And also I can go to Exchange admin portal via this. So, in my opinion I can use all deep settings also.

Office 365 licenses (full) for name.lastname@company.fi. Portal show "Office 365 business standard".

I create also shared folders. Today shared folders found from "Teams groups". Log in to portal.office.com/adminportal, "Teams-Groups", and then "Shared mailboxes".

My conf: Office 365 business standard found name.lastname@company.fi. ("john.smith@company.fi", "alice.brown@company.fi" as example.)

Shared mailboxes sharebox1, sharebox2, so, it is possible receive email sharebox1@company.fi, sharebox2@company.fi etc. (in real life share box names are bookkeeperteam@company.fi, orders@company.fi, helpdesk@company.fi etc etc.)

CONFIGURATION IS FULLY WORKING. It is, in Outlook it is possible receive and send emails, shared folders with messages are available etc.

------ 

HOW I can add shared folders to Thunderbird? Clean install tested.

1. LIcenced mailboxes work properly in Thunderbird. Tested.

name.lastname@company.fi:

Server: outlook.office365.com, port 993 Username: name.lastname@company.fi Connection security: SSL/TSL Auth: OAuth2

And smtp: smtp.office365.com, 587, starttls, oauth, name.lastname@company.fi.

This configuration work properly, and it is possible receive and send email from Thunderbird.

SHARED FOLDERS

It is not possible add shared folders.

Server: outlook.office365.com, 993 Username: name.lastname@company.fi/sharebox1 (where name.lastname is real working account name, just same as in position 1- working account. Also this sharebox1 work in outlook.) Connection security: SSL/TSL (no difference is it this or stattsl) Auth: OAuth2

(I am sorry, all my systems are native language, so I must translate---)

OK: Now I try use this shared folder. It is visible in Thunderbird. But immediately thunderbird open Browser and ask password: "name.lastname/sharebox1", wrtite password. Now I put same pw as in this account (name.lastname..). "Password wrong." I try empty password. I try account password.

SO: HOW to add shared mailbox in Thunderbird? This information "name.lastname/sharebox" not work. Is it any other method? Or any Exchange setting modification make this?

If I try to import Mail Message in Outlook 2016, the progress will not proceed at 0%

Both Outlook and Thunderbird were running on 64bit

How to solve this?

Hi there, My preview panel is working very badly, it either shows the content of the email or is completely white. What can I do to remedy it? - In some cases the emails appear in very strange codes, thousands of lines like this (iVBORw0KGgoAAAANSUhEUgAAAPAAAABGCAYAAADyxhn6AAAAAXNSR0IArs4c6QAAAARnQU1BAACx jwv8YQUAAAAJcEhZcwAA) - in other cases, totally blank - in other cases it's everything ok It's working fine, receiving and sending all emails.

I have windows 11 home edition. Thanks

I like to read, file, or delete my email when it arrives. Suddenly my inbox showed 18,642 unread emails! I've read them all, but I cannot figure out how to return my count to 0 without deleting each one individually. I don't know why this happened. Can anyone help me return my count to 0?
