I don't wish to use the calendar that comes with Thunderbird, but instead continuing with my Macintosh iCal.

1) How do I switch off the Thunderbird calendar function? 2) How do I get the calendar invitations sent to me as an ICS file attachments, that I can open in Mac iCal. Just like in Airmail and in Microsoft Outlook.

When i try to update my schooles secure mail, i get the nev certifikat and the Root, and Ca1 under autoreties and give it the right rights but it keeps giving me this error message " Certificate verification failed with the following error: The peer's certificate issuer is unknown. (Error code: SEC_ERROR_UNKNOWN_ISSUER)"

Why Does Thunderbird Hang When Saving Draft? Right after creating a new email, and I "Save to Draft", Tbird says "Copying messages to Drafts" at bottom left of GUI.

The only way I could see to clear the "Copying..." message was to have Tbird check for mail in a different account. When I check for the draft in Drafts, it's not there - it's no where I checked except the original still in it's own opened GUI that opens when using "New Message"

Bottom line - can't save drafts.

I'm up to date on Windows 10 with version 151.0.1 of Thunderbird. My preference is to discontinue using Windows and move to Linux Mint. The Software Manager in Mint installs and manages Thunderbird updates. I like the idea of Mint managing my software. However, the latest version is 140.11.1esr. Consequently, moving my data from Windows to Mint is not possible. A profile problem is flagged.

I've switched off automatic updates. I'm wondering how long it will take Linux Mint to catch up to v150. One solution is to install v150 independent of the Mint software manager, but I'd rather not do that. I'm wondering if there are any workarounds.

On Sunday, May 7, my Thunderbird program suddenly stopped responding (neither the shortcut nor the program itself will run); clicking on the shortcut icon or attempting to open or run the program itself causes the "loading" or spinning wheel icon to pop up, run for about 10 seconds, then stop.

I've used Thunderbird as an email client for my Sonic email account on my pc for over 8 years without any difficulties until now, and now seem to be locked out of my Thunderbird account. I cannot access it to confirm the version, although I believe it is current, since it appears to update automatically.

My Sonic account continues to function normally, but I keep (save) all incoming and outgoing emails in my Thunderbird system and now am unable to access any of those, and unable to access my Thunderbird account at all..

I've consulted with Sonic over this; Sonic maintains that any difficulty must be on my end connecting to Thunderbird, and suggested that I might have changed the account password. However, I have not changed the password, etc.

Please help asap.

Thanks, immensely.

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

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.

My email provider provides "Disposable Email Addresses" - aliases which still direct mail to my inbox but don't expose my primary email to any web sites etc. I provide them to. It's very handy for registering for mailing lists, product vendors etc. since if one gets leaked, it's no big deal. I can drop the email again, but at least I know who was responsible for leaking it (I still get spam to my old Myspace account). My problem is that I'll occasionally have a need to reply such an email, and by default my From: address is my primary email address, not the one in the To: header. This is confusing to the recipient (since it's from some unknown email) and also exposes my email unintentionally. Is there any way to configure Thunderbird to always reply using the To: address? If there are multiple To: or CC: addresses, it could perhaps be specified with a wildcard matching any of my aliases. I can do it with Identities, I know, but I have to set that up before replying and I frequently forget.

This is a Thunderbird question so be patient :). All of a sudden I was locked of MyMail and Mail on iPad and iPhone so I updated my comcast password but I can't update it in Thunderbird because it isn't accepting my old password. When I try to send a message there's a window that pops up that says why it wasn't sent and it says enter new password but when I click on that it goes away and doesn't let me enter one. When trying to figure this out I googled and it suggested removing all providers if I wanted to use all new credentials. So I have to add Comcast back in but I don't know how. So now it doesn't give me the option to show passwords. So i screwed up. How do I straighten this out? Plus it is now almost midnight and I have not received any new emails since this morning. I think part of this is the business about having to change to a new Comcast email system. But I still need help with the password issue. I have an appointment with Comcast tomorrow afternoon so hopefully I can start to get emails in MyMail. TIA.

I want to collapse all folders in my email account.

I have a lot of them, and I don't want to close/expand them all individually. I want to quickly close all or expand all

Is there a button to do that ?

Tried getting help from SPAMfighter, but they are closed for the day. I uninstalled SPAMfighter and reinstalled. No luck. No toolbar. Is this version of Thunderbird, (151.0.1 64-bit) having issues with SPAMfighter as some of the previous versions have had?

Subject: Persistent Column and Folder Layout Issues — Not Being Saved Between Sessions

This is a follow-up to my previous support requests regarding two ongoing problems that significantly impact daily usability.

Column Settings I manage multiple accounts, and my preferred column layout is: Starred, Read Status, Attachment, Subject, From, and Date/Time. I do not use Threads, Correspondents, or Spam Status columns. Despite setting these preferences repeatedly, Thunderbird fails to retain them. Every day I must spend time reconfiguring columns across some or all of my accounts — the state varies unpredictably from one session to the next. This is a persistent, daily frustration that costs meaningful time. Most other major email clients save and reliably maintain column preferences. I'd expect Thunderbird to do the same.

Folder Panel Layout Two problems occur regularly when Thunderbird loads:

Folder order — Standard system folders (Inbox, Sent, Drafts, All Mail, Trash, Spam) should appear at the top of each account. Instead, Sent, All Mail, Trash, and/or Spam are frequently scattered among custom folders, with no apparent consistency.

Folder expansion — Most or all folders load in an expanded state, exposing every nested sub-folder regardless of whether they contain unread mail. This creates unnecessary visual clutter and requires manual collapsing each session.

Again, this behavior is uncommon in other widely-used email clients. Summary These are not one-time glitches — they recur daily and represent a significant usability gap. I'd appreciate confirmation that these are known issues being tracked, or guidance on a reliable fix. Reformatting the interface every morning is not a reasonable expectation for users.

Hi, I can receive emails (via satellite internet) but not send. I logged on to my email provider and I can send emails from there but not from here. any ideas?????

I am moving my Thunderbird (32 bit) data from an old Win 7 computer to Linux Mint on a new machine with Thunderbird 64 bit. I have followed all the advice to copy the old computer profile to the profile folder in Mint, but nothing appears in Thunderbird. My pop3 email server has 2-factor authentication; I can set this up and access or send new emails, but I can't import all my old email folders. The old Thunderbird is version 115.18.0 (32 bit) and says it is "up to date on esr update channel" The Mint Thunderbird is 140.0.6 esr (64 bit) and was recently installed with Mint.

As these versions are 32 bit and 64 bit respectively, I don't see how I can make them the same version, as recommended for transferring profiles.

How can I make this work?

I just started using Thunderbird about a month ago having switched from Gmail. I've tried to forward a few emails to my personal gmail account but they are not going through. Any suggestions.

Old win 10 computer with Thunderbird pop account. Want to move all saved e-mails from old computer to new computer. New computer (win 11) installed thunderbird as an IMAP account. Alternatively, if not practical, how to save old e-mail in readable format. Thanks

I have 6 email accounts linked to Thunderbird. I noticed today on one of the accounts, along with inbox, drafts, sent, etc., there is now a spam icon. I didn't change any settings or even look at that email account today. This is the only account with that icon and it won't allow me to delete it. All settings between all accounts are the same, just this dang spam fire icon that I can't delete

a power shortage messed up my computer and i had to re-install thunderbird. now when i type in the initial letters of an address that is in my address book, thunderbird no longer completes the address.
