I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

My unified folders are properly picking up e-mails from my account except for the SENT unified folder. The unified SENT folder is empty. I've checked the Properties settings, and they are correct (the same setup as the other unified folders which are working). I've attached a view to illustrate the problem. As can be seen from the attachment, the account's SENT folder has 121MB of message data while the unified folder is empty. Also shown is that the account's SENT folder has been selected in the unified folder Properties settings which should bring in the account's 121MB of data in it's SENT folder, which it apparently doesn't do for some reason.

Any suggestions to correct the problem would be welcome.

I've appreciated using Thunderbird for an ad-free Hotmail experience for quite some time. I've changed my Hotmail password every few weeks lately and Thunderbird worked fine when I entered the new password at the prompt when Thunderbird started.

Just now however, I needed to get into my Microsoft account that uses the same password as my Hotmail account. My login to Microsoft failed. Trying to understand why, I looked in Thunderbird at the saved password for Hotmail's server:

oauth://login.microsoftonline.com (https://outlook.office.com/IMAP.AccessAsUser.All

https://outlook.office.com/POP.AccessAsUser.All 
https://outlook.office.com/SMTP.Send offline_access)

The saved password was a 464 character long ASCII string totally irrelevant to the password I'd selected for Hotmail and Microsoft.

I went through the password change process for Hotmail, was then able to get into my Microsoft account and restarted Thunderbird. As usual, Thunderbird asked for the new password. I entered it and was then able to receive new mail from the Hotmail server in Thunderbird. However, again, the saved password in Thunderbird for Hotmail was not the password I'd entered.

Next, I deleted the saved passwords in Thunderbird, restarted it and this time it prompted me to be sure I'd downloaded it from a reliable source. I've never seen that prompt before. It came with my Linux Mint installation, so I thought it would be safe, but again there's an irrelevant password saved for my Hotmail account.

It's like it eventually changes my password for Hotmail and Microsoft since I can get mail through Thunderbird with the odd password it saves, but if I use what should be my password for Hotmail or my Microsoft account via a web page interface, the password doesn't work.

I'll have to stop using Thunderbird if this continues.

I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

Hello, While the display size is correct on my MacBook Pro 2021 screen is OK, it is huge and unusable on my second monitor (see images). My layout.css.devPixelsPerPx is set at 2.5. If I set it at default (-1), the external monitor display is OK, but the internal monitor is so small that it is unreadable (to the extend that it was actually hard to figure out how to revert back to so I moved the window to the external monitor). This is a bug. There should be a setting per monitor or the default should follow the System Preferences setting for all monitors.

Please fix this quickly!

Thank you, Alain Damlamian p.s.: I tried to upload two pdf images but they were refused (why only accept jpg ?)

I want to sort my mails in columns but there is no way i can find this column picker icon that is mentioned in your tutorials. Is there another way to get the columns with date-subject-sender? Regards Leonie

I've recently decided to switch to Thunderbird from Windows Live Mail, which is no longer supported. I also use Mailwasher PRO which displays emails on the server and allows me to delete unwanted emails from the server. If I download emails to Thunderbird, I expect them to be stored automatically on my PC. However, when I subsequently delete them from the server, using Mailwasher, they are deleted from the inboxes in Thunderbird as well.

I'm guessing it's a setup issue but am struggling to find what is wrong. Thanks in advance for your help.

How do I move all my message filters and address books from my Windows desktop PC to my Windows laptop?

I have three email accounts and ten address books. (The message filters use the address books to sort messages into folders.)

There are a bunch of abook* files in the root directory of the profile. Is it sufficient to move these to the laptop, or are they indexed somewhere?

There are msgFilterRules.dat files in many subfolders of Mail and ImapMail. Is it sufficient to move all of these into the corresponding folders on the laptop?

Is there an easier way to do either of these?

I'm able to receive messages in Thunderbird from my hotmail account but am unable to send them. This problem started the version before 115.4.3. This use to work. I have not changed any settings. I've tried removing the account and re-adding, but that didn't fix the issue.

The error message is: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.office365.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Attached are images of the servers settings I have.

Help!

After the latest release of THunderbird, the default view is showing emails in a thread. I have tried all the recommended solutions I can find and none of them work. How do I unthread?

hi there

i have been keeping my local folders stored on my microsoft sharepoint but need to move them to my local drive due to storage restraints on my sharepoint.

the first thing i did was to change local folder location to my C drive (I know how to do that).... then when I started looking online for how to move the local folders, I decided I should probably start by directing thunderbird back to the original local folder location on sharepoint... but now I can't seem to undo the change and whilst I can see my local folders on the sharepoint, i don't know which folder to select so that thunderbird will display my local folders correctly.

see attachment 1 - this is where I am directing thubderbird to find the local folders

but the local folders are looking like attachment 2

I'ved tried directing it lower down in the file hierarchy, or higher up, but nothing seems to work.

Can you help by telling me which folder I should select?

please and thank you!!!

I have two Google (yes, Google, not gmail) accounts. When setting up my gmail in Thunderbird, I was prompted to enter the Google account. I have entered the wrong one. Consequently, I cannot access my gmail: "Unable to log in at server. Probably wrong configuration, username or password."

I have tried all ways I have found in this forum to get rid of it again, such as editing the prefs file, but to no avail.

How can I remove the Google account from the Thunderbird settings to be able to insert the new one?

Thanks for your help in advance, Matt

I just recently downloaded Thunderbird after using Mac Mail for years. Mail suddenly refused to display messages and no one on the Apple forum could figure out why. So I was advised to download Thunderbird. So far, I'm not a fan. Here are my issues: 1. Unread messages in the Inbox are in bold. But the bold is so close to the normal font that I can't tell them apart. Is there another, better way to mark unread messages? A tick/check mark? A coloured background? 2. Messages are automatically organised into conversations. But when the latest message comes in, the inbox message doesn't go bold. So there is no way of knowing where to find it. I have to go through all messages that have a conversation (more than one message in the inbox) and find one where the latest message is in bold at the bottom. It's a royal pain. I see the number next to the account on the left, but nothing is in bold on the right. Grrr. 3. The conversations are the wrong way up. I want the most recent message at the top, not the bottom. I would actually prefer not to have them in conversations at all, just the most recent message, but I realise that is probably asking too much. 4. There is no number next to the Thunderbird icon on my desktop when I get a message. I used to appreciate this in Mail. It told me if it was worth going to my inbox. With Thunderbird I have to open the program to find out. Ok, that's enough for now. I'd better not get started on the shortcomings of the search function, or how to bring the unread messages to the top of the inbox list... There are just too many issues to address is one posting. Thanks for any help you can give.

I am trying to set up 3 yahoo email addresses in Thunderbird for myself and my family. I was able to set up the first one (mine) successfully using Thunderbird's email setup wizard which uses Oauth, but when I try to set up their email addresses, for some reason it redirects the Oauth login to my email address, so even though my family's email addresses are set up, they end up downloading my emails, so all email addresses download the same emails. I have never experienced this problem before and hope someone can help.

I'm trying to filter out junk phishing emails from the Temu company.

Every email comes from a different email address, probably farmed, and every subject line is different but usually has temu or Temu in it somewhere. eg TemuDelivery, Your Temu_pallet, temu_ arriving soon

I've set up filters to delete the message if the subject 'contains' temu but that only seems to work if the subject has temu as a word on its own and in lower case. So I set up other ones looking for Temu_ temu_ TemuDelivery etc.

Is there way to filter on just a string of characters in the subject line instead of looking for whole words as it seems to do?

i.e. delete the message if the subject contains temu in upper, lower or camel case and whether or not there are other non white space characters before or after it?

I do have junk training on but that is taking a long time since these are sort of 'genuine' emails sent from hundreds of different genuine email address and so the headers don't seem to indicate a high spam count.

i made a new,local windows 11 account coz there were some problems with windows in the current account. how can i transfer all -settings, local folders etc from this current account to the new one? in this new one account tb is installed and has connection to my provider.

Hi, As the title suggests, I am unable to delete emails from my work Microsoft account.

On attempting to delete an email, the following message is displayed:

"The current operation on "Inbox" did not succeed. The mail server for account [email] responded: [TRYCREATE] The destination mailbox could not be found."

Checking the account settings, it seems Thunderbird cannot see the "Deleted Items" folder (it only shows Inbox and Drafts). I have attached images to show what I mean, comparing with a personal Microsoft/Outlook account where it sends deleted email to the correct place.

Using the latest Thunderbird version that is available on the Microsoft Store version on Windows 11. (115.9.0) I have tried removing and re-adding the account yet the problem persists. Any troubleshooting ideas welcome!
