Thunderbird Community Forum

All of a sudden today when I click onm add theme to Thunderbird I don't get the usual dialog. I am told the the site wants to install a theme and I am only presented with 'Learn more' and 'Cancel.'

Any ideas why? James

Hello helpful community, Yesterday after first updating my mac ios, I updated Thunderbird (as directed) on my macbook pro and discovered that my local folders are gone. I now have version 128.7.0esr. I have read other conversations here about this problem but they are WAY over my head, and seem to do with PCs. Can you help me restore my local folders with instructions I can hopefully understand? Thank you!

Any thoughts on this will be very much appreciated. I have 2 email accounts with Yahoo and am using Thunderbird to access them. It used to work properly, but now I can receive emails on both accounts, but can only send emails on one of them. The other account gives me the error message: "Sending of the message failed. An error occurred while sending email. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again." When I then look at the SMTP user name, it shows the name for the other account. When I change that user name to the correct name, I can then send emails on that account, but the process also changes the user name in the second account, such that it no longer allows sending emails. In other words, when I go to 'account settings' and set the SMTP user name for account 1, then go to account 2 settings, I find that the account 1 user name shows up. If I then change the account 2 user name and go back to look at the settings for account 1, I find that the SMTP user name in account 1 has changed to the same as I just changed in account 2. Additional info: Prior to this problem, I had gone into my emails on the Yahoo website and changed the password on both accounts. When I then opened Thunderbird it asked me for the new passwords for each account, as it normally does, and everything looked fine until I tried to send using the one account. Thanks for any thoughts.

How do I update the SMPT server password in Thunderbird. Updated IMAP pw and system receives email fine. Cannot send messages, "Outgoing server (SMTP) error". SMPT password needs update.

Using Nord VPN:

  All gmail accounts are set up for imap on Thunderbird:

    1) With VPN on, I cannot send/receive emails from/to my gmail accounts using Thunderbird.
    2) With VPN off, I can send/receive emails from/to my gmail accounts
    3) With VPN on or off and logged directly on mail.google.com, I am able to send/receive emails

And, yes, I have tried different port numbers and all server info is correct for imap on Thunderbird as indicated by #2 above. This change happened overnight and Thunderbird always worked faultlessly with Nord VPN for years. I don't think we can blame Nord VPN for this, given #3 above.

Your thoughts?

The Tools menu in the menu bar lacks the "Options" choice. How do I find it? I have updated Thunderbird and it is still lacking. I need it to fix some "Attachments" issues.

When setting up a new email account in Thunderbird I get the error "incoming server already exists" But when I go to the inbox there is no account shown. Do I have to clear something? How would I clear the account that exists if I can't see it?

My thunderbird taskbar icon just started to display arabic numberals instead of roman numerals for the count of unread mail. It's weird because it doesn't always display the arabic when hovering over the taskbar, but it has done it more often than not the past few days.

I need to import an MBOX file, but every version of ImportExportTools NG says it is incompatible with my version. I checked and it says I am up to date for Thunderbird, version 136.0. What can I do to be able to use ImportExportTools? Or is there another way I can import the files?

My Thunderbird Icon disappeared So I can not get into Thunderbird to update However the app is still installed but I can't approach it How can I update on this basis?

I have been using Thunderbird for my e mail for decades, and always with the IEEE email service as the address. As a result my address on IEEE.org has been my standard identity for at least 30 years, and Thunderbird has been my means of communication with it. However the IEEE has now removed Mozilla and Thunderbird as a means of communication with the e mails arriving on their website. It is now necessary to use a google controlled app which is unfamiliar to me, does not provide service to my personal machine and seems to sort through and remove contacts without asking. Complaining to IEEE seems to be pointless. I personally do not like to have all my contacts and private data passing through Google as it seems intrusive and tries to control every aspect of my internet contact including my cell phone. I understand that this action of IEEE is against all e mail programs other than gmail which is actually running their site I do not know how to extricate myself from the IEEE server while maintaining all of my previous contacts. I thought I should write to outline the problem I am facing and to ask where I can find a reliable e mail server after this debacle. Any suggestions would be appreciated

Hi - I have been looking for over 2 days. How do I import all my data (emails, addresses calendar) from Outlook to Thunderbird.

I have tried Import tool within Thunderbird - import from Outlook. I tried MailStore and was totally confused - the terminology was strange. I managed to make an archive - it took ages to find where it was and I still do not know the file extension.

No videos...nothing.

Thanks

I installed the current version of Thunderbird yesterday. I am using IMAP. It is only showing the emails received since yesterday - nothing older. I can see the older emails via my ISP browser based webmail interface.

I have tried recreating the account settings, synchronising All, synchronising past 5 years - but it stubbornly refuses to fetch the older emails.

What other steps can I take to resovle this?

Thanks

I'm just starting to use Calendar in the latest version of TB. I see that you can add little category color bars to each event. I tried to add a new category, but it disappeared from the dropdown menu as soon as I added it and a color bar never appeared in the event on the calendar display. How can I add and subtract categories? Can I change the colors assigned to categories?

I followed the article "Switch from POP to IMAP account" successfully. But I am left with two problems: 1. Whenever I try to send an email I get the error message "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.lcn.com timed out. Try again." I have to use webmail or my mobile phone to do so. 2. After I switched, Thunderbird created a new folder for incoming emails with the title of my email address. I already had a default folder using my account name, so I copied all the new emails to that and deleted the new one. I then went to Server Settings and changed the User Name to my Account name, which it was previously. However, my incoming emails now do not appear at all, I can only see them on my phone or webmail. I have checked my settings over & over but I cannot see anything wrong. I would include some screenshots but the print screen button on this temporary keyboard doesn't seem to work properly. (I am in the process of transferring all my work to a new PC running Windows 11.)
