Thunderbird Support Forum

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?

For a few weeks I have had a new problem on my new Windows 11 Lenovo laptop, and also on my wife's older Dell laptop. We have been using Thunderbird for years without major problems. I loaded the latest version of Thunderbird on my new laptop and it seemed to work ok at first. Now I have a problem with intermittent failure to send normal emails on Thunderbird. My wife has noticed the same problem on her laptop Windows 11. I asked iPrimus support (who are supposed to support Hotkey) but they say it is not their problem but Thunderbird's. We RECEIVE emails ok, and sometimes pressing SEND will work immediately, sometimes on the second press, and sometimes not at all. This generates a message "-- Unable to authenticate Outgoing Server (SMTP), smtp.hotkey.net.au -- Check password and verify authentification method in Account settings/Outgoing server SMTP" We both use Trend virus protection.

Account name: mail.hotkey.net.au Outgoing Server: smtp.hotkey.net.au Server Settings: Server name pop.hotkey.net.au

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?

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 have 4 different email accounts, all managed by IONOS. These have all been set up under thunderbird OK. But when I send an email from 1 of these email accounts I always have to enter my password for that a/c. With all the other accounts, this is not necessary. I do not use Thunderbird or Firefox password managers. I assume that I must have made an error in setting up the outgoing details when setting up that particular account in Thunderbird, but I cannot find a way of checking if that is the case.

I have had a few emails that did not show up in the inbox listing, so the message count at the top indicated more messages than were listed. Doing a search showed them, and by moving them from the search results to another folder, and then re-searching and moving them back, caused most of them to appear. But not all - I still have a message count of 20, but only 19 listed, see photo 1. Photo 2 shows the hidden email (from Barry Chandler). So the email is there, it's just not visible!

Bug forever (years, versions, reinstallations).

Failure by filters whose action is to DELETE. As stated in subject. Uncomplicated.

Other filters work (they distribute msgs into specified folders).

Thunderbird on my top of the range Win11 laptop was working perfectly until it self-updated to 115.10.1 a couple of days ago. Accessing messages already in the various folder is fast as usual. Unfortunately anything like deleting, downloading a new message is excruciatingly slow : several seconds to click and delete in the inbox. Several seconds to access a message just downloaded. The first time it happened I had a whole bunch of messages deleted because the I kept clicking when I saw no action. It seems to me like it has problem updating the messages in the inbox. Very painful for something that was working so well.

Dzień Dobry

Poczta Thunderbird nie ściągą nowych wiadomości, usuwane teraz stare, wracają do folderów głównych. Przy odbieraniu wiadomości pojawia się komunikat jak na zdjęciu. Ostatnia wiadomość pobrano ok. 100razy.

When I delete an email, it usually goes to the trash, so I can find it again. Now the emails are deleted permanently and disappear. How can I keep my emails in the trash? Sincerely Helle

I have Thunderbird 115.10.1 (32 bit) and Windows 10 Pro, 64 bit.

The reminder function quit working...nothing at all

I'll add an appointment ask for a reminder, but nothing happens however it used to work

I used to get a reminder email as well as a notice sent to my phone, but now nothing to include the folks I have invited to the event. No reminders for anyone. I have checked Notify Attendees and Separate Invitation per attendee on the Edit Event pop up the by nothing I do seems to work.

The goal is to get the reminder to the phone screen(s) and emails.

Many thanks as I'm lost on this one

Thanks!

I understand the basic differences between unread folders and unified folders what I don't understand is why two of nine my accounts are listed in both unified folders and unread (see circled in red) how do I remove the two accounts from unified folders or

add more to it
and what makes it confusing is that the subfolders aren't the same when listed in unified or unread

Hello,

I have just imported my old email from Outlook to TB Local Folders. Everything works out except some of the email (not all) show a wrong date in the email list. The date show a future date like 2/7/2101, 6:28 AM. Please check the attached image. Any idea?

Just switching between inboxes can cause up to a 10 second delay with Thundebird "not responding" with the spinning wheel. It has been like this for the last few laptops I've had and through all the updates and I am getting ready to call it quits. I did a performance recording of me just clicking through the different folders and then it locks up on one. You can see it here https://share.firefox.dev/3WlrRi9

I am using a primary gmail imap account, an office 365 imap account, and another imap account from an ISP.

On Win 10 LTSC, CPU: 16 x 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz @ 2304 MHz 10240 KB Cache, MEM: 65277 MB, 60% (39120 MB) free, GFX: NVIDIA GeForce RTX 3080 Laptop GPU 16192 MB

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.
