Thunderbird Community Forum

I've recently changed one of my emails from example@cpsupply.com to example@yardsignninjas.com and I've been able to send email to other accounts most times. Sometimes the email never gets to the address I'm sending to. However, I haven't been able to receive any emails to the example@yardsignninjas.com and I need to verify it for an application i need to use for work. Why isn't this edited email address receiving mail when I use the new name?

To whom it concerns, It just happened yesterday June 11,2026. I put in my password to my e-mail to open it and it stated that my e-mail account is being processed. Said to wait until processing is complete to get messages. I have never had this issue, I been with Thunder Bird e-mail for years. It isn't even showing my e-mails that I had in my inbox on my e-mail. If you can please help, I need my e-mail up and going. Thank you, Chris Note, it also said that Thunder Bird had crashed in a box, they wanted to know what page I was on. I am not understanding this.

In Thunderbird 151.0.1 [64 bit] I get the following error message: Error Inbox - inbox on .....[my email address] "There is not enough disk space to download new messages. Try deleting old mail, emptying the trash folder and compacting your mail folders and then try again." I did all of that, even went into windows disk cleanup to free up more disk space. I get the same error message. I have 3 email accounts in Thunderbird, only one account has this problem. When I use Outlook express I do not get any error messages but I do get a malicious email that AVG intercepts. So how can I purge bad email from Thunderbird ? Or what else may be going on and what else could I try ? I have deleted all old emails, in Thunderbird, I routinely delete old emails. Thanks alot Sam

Using Provider for Exchange Activesync v4.18 because my calendaring host requires EAS v16. I have recurring events (e.g., multi-day hotel reservations) which seem to SHIFT a day earlier than originally specified after a synchronization.

All folders are shown ticked but they do not appear. I can view one folder at a time with Go>Folder>my account>Inbox(say).

Using IMAP. Firefox 151.0.4 I don't know what I could have done to cause this.

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.

Hello,

When I forward message with some attachments, new windows opens, with e-mail and attachments, and I can open and review them. If I edit (or not) that message, for no more than couple minutes, I can send it without problems.

But if I left windows open for some time (let say more than 10 minutest, but I not figured out exact amount), I can't view attachments. If I double-click on icons, nothing happens. If I try to send that message, I get message about missing file.

I've noticed, that after opening new window with forwarded message, attachments are copied to %TEMP% folder as nsmail.pdf (or jpg or something). After some time (10 or more minutes as mentioned before) these files disappear, and then problem begins.

The same problem occurs with MAPI generated message with attachment.

Problem tested at two PCs, one PC with 32bit viersion of TB and IMAP, and another with 64bit and POP.

An address book that I was using for years suddenly stopped working. It was called 'nachbarn'. I had to rename it to 'nachbarn@here', and it worked again. This is on Linux, and a week ago I have been using this list with its old name. But in betwen I changed my account from POP3 to IMAP, which may have contributed. Since there are plenty of complaints on the Internet, I'd suggest to change the plausi check for the address field, so that the address must either contain an '@' or be the name of a list or address book?

Thanks a lot!

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 ?

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 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.

I have Thunderbird installed for lots of users on windows 11. Recent updates caused Thunderbird to ask again to set as default, as is normal. However, if you ask it to set as default it brings up a UAC dialog. However, I have installed as a user, and am asking to change a user setting. UAC is inappropriate for the situation.

If I ask Thunderbird to uninstall is again pops up a UAC dialog even though it is not necessary and inappropriate.

Why is Thunderbird asking for more permissions?

I installed as the current user with default installer settings.

This is the error message I get when trying to download email

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

All my other emails work fine, same computer same "Local Folder"

Receive popup message: The certificate for mobile.charter.net does not come from a trusted source. In trying to send email, popup message: Sending the email failed. Peer's Certificate issuer is not recognized. The configuration related to mobile.charter.net must be corrected. Then it wants me to Add Security, Get Certificate.
