Thunderbird Support Forum

With some incoming meeting invitations (some Teams, for example) TBird asks me to enable a calendar to process. With others (.ics for example) VueMinder comes up automagically and asks me to accept the entry.

Where and how do I enable VueMinder Pro as T'Bird's default calendar app?

Unable to SEND email messages on thunderbird, This problem just started last week. I have a desk top computer, CenturyLink is my browser, Norton I have talked to and they say it is not a Norton problem as the message has no Norton logo or any other message refering to Norton. The error message reads: outgoing server (smtp) error The Server Responded: (C20) messanger blocked

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: [C20] Message blocked..

I have a 2021 M1 Pro MacBook Pro. Thunderbird display a number of the received emails in XML. It displays OK on my Intel iMac. How can I tell if Thunderbird is using Rosetta? TIA. --Dwight Early

I'll explain by means of an example.

When I send a message, both Thunderbird and my email service allows me to alter the 'from' address. I place an underscore character after my id and some chosen text.

So, I send FredCo an email message from this address: [my id]_fredco@[my domain].co.uk .

FredCo replies to the same address (and possibly stores email address).

My email delivery service recognises the address format and delivers FredCo's message to me. Because of the address format, I can see that the message is from FredCo.

(If I receive a message with that address from someone else, I know that FredCo has released my email address.)

Now when I reply to FredCo's message, the 'from' address defaults to my basic id, [my id]. And that's the problem.

I want it to default to [my id]_fredco because if I forget to change it, FredCo will record a new address, and I won't be able to detect whether FredCo has passed that email address to some other organisation.

OK, I could set up a new id for use with FredCo, but I would need dozens of similar ones - one for each person or company I contact.

Is there a solution to this problem or an add-on that will achieve this?

In the past, the entire event title appeared in the event box when viewing a Week. Now, the frame shows only one line of text and truncates the rest by replacing it with dots. This means I can't get an overview of my week. I've tried looking through all the options and searching online with no luck. How do I get it to wrap text like it did before?

I have created many filters for below sender and none have blocked or been forwarded. I am using Ionos as my mail server and their email filters and still I receive emails from below. Why and how to stop? I even tried forwarding blocked emails I try to block to my gmail account hoping not to delete emails from senders I want to receive emails from. Does not work. How? Thanks. And below is from this morning.

Thunderbird will not display new messages and is repeatedly requesting the password. When I type in my password it says it failed to login to the server. I have not changed my password. I am able to view all of my previous messages and folders.

It did briefly load new messages a few days ago, but has been stuck again.

This is probably a FAQ, although I can find no mention of the question using the search facility, so here goes...

I am just starting to use Thunderbird for my Usenet groups, having finally given up on Forte Agent. I don't seem to be able to find a way to define a filter to run across all subscribed groups - if I define it to operate on the news server (tweaknews) then it doesn't work on ANY of the groups. Surely I'm not expected to define the same filter for every single group, individually? What am I missing?

Thanks for any assistance.

I've recently migrated to Thunderbird, from Apple Mail. I've managed to establish one email account (which runs through Google email servers) but ran into trouble when I tried to add my iCloud account. I've tried 3 times to add the same account, and it fails every time. On attempt one, I generated an app-specific password to use - however this was rejected by TB - the message being : 'unable to login at server. Probably wrong configuration, username or password" I made sure the user name was entered correctly (ie without the '@iCloud.com' part, and checked the password was correctly entered. I also checked the port settings, server addresses etc. Please see attached file.

I also generated a new app specific password and tried that - same result. I tried the original iCloud password too - still no luck.

Please help...

I recently received an email with the "Disposition-Notification-To" header set. When I read the email, my Thunderbird client sent a "read receipt" to the sender to inform them I had read the email.

I do not want Thunderbird to do this. How do I prevent it?

Looking through the configuration options, the only vaguely relevant setting I can find is "Determine how Thunderbird handles return receipts". I don't know if this is the correct thing to set but, even if it is, it doesn't seem to work. Under "When I receive a request for a return receipt", it's already set to "Never send a return receipt". I also have Thunderbird set up to block remote content in the message to prevent html-based read receipts, so how is my client still sending them?

I only know that this one was sent because the email address it sent to was faulty so I received a failed mail delivery message. Who knows how many others Thunderbird is sending that I'm simply not aware of!

Apologies if this has already been answered but i honestly don't know what terms to search for to find the correct answer. Problem: My gmail account receives email from a BT Internet account. When I reply the owner of the BT Internet account doesn't receive my email so I have to remember to change the "to:" address to one of their other email accounts. Sometimes I forget and a few days later wonder why they haven't replied. Can I automate this? (I'm not going to try and resolve the source of the problem which is probably the BT Internet account because the user is elderly and I'm remote from them). I did try to set up a message filter ("After Sending" ticked, "To" contains abc@btinternet.com, "Forward Message to" abc@otherdomain.com) but it only works when run manually and even then it forwards everything that matches in my sent folder. I don't really want to forward the message, I want to change the "to:" address. Is what I'm asking possible (assuming I've described it in sufficient detail!). Many thanks for your help.

Hi guys,

Back in 2018 when I started using Thunderbird I check in for an option to save all emails - sent and received on my computer hard dick. Now I'm out of space and I want to delete those and opt out of that setting.

My questions are two: 1. How do I opt out form the setting? 2. If I do opt out, I'm still going to have the emails sent and received on my email right, they are not going to go away forever? I presume you should be keeping them on cloud or something?

Please let me know. Regards Yosif

Hi, Looking for some assistance with syncing my profile and folders

I searched through the forum and have, somehow, managed to retrieve my profile. I used "bitrecover-mbox-fixer" to completed this.

The issue I have now is that my inbox has 1300 new emails but my Local Folders inbox has not synced and none of my message filters have activated

How I could disable the single message search (message open, press ctrl+F) from automatically going back to the top of message while searching a phrase from within single e-mail message?

Why I cannot get alert pop-up saying: "You reached the end of the message. Do you want to continue from top" and Thunderbird insisting on me selecting "yes" or "no"?

In other words, what advantage I or Mozilla gets from me missing the pale gray text "Reached end of page, continued from top" on white background while I'm trying to find the search phrase in certain context on my mail message?

Thunderbird version: 91.3.2 (32-bit), Windows 10: version 10.0.19043 Build 19043

I'm running TB 91.3.2 on a Mac Mini running 10.13.6. For the past couple of months, some of my email winds up in the recipients' Spam folder. (Some have me in their Address Book, some don't.) This is not a mass mailing. I'm sending email to people I know.

How do I stop this?

How can I delete a recurring event from this date forward? I only seem to get the option to delete the current event or all of the recurring events and i want to be able to keep the previous occurrences as a record. This is a feature on most other calendars I've used. Am I missing something?

Thunderbird recently updated and I lost ALL my emails :(

I am using IMAP - now the emails have synced they are also gone from the ISP server.

I googled some solutions and can see in the /user/appdata there is a folder called "mail" which looks like it has all my old inbox folders and msf files .... however the new Thunderbird update looks like it is using a new folder structure "imapmail" which I can see does not have any of my old emails folders or msf files in there.

I copied all the files from the "mail" folder over to the "imapmail" folder and relaunched Thunderbird. I can now see the old folder structure under my inbox however I get an error message when I go into the folder "unable to open the summary "xxx". Perhaps there was an error on disk, or the full path is too long"

When I right click and go to folder properties there is no location path.

I need my emails and so disappointed an update has caused me to loose EVERYTHING ... please help!

I moved to a new PC and installed 64-bit Thunderbird (had 32-bit on old PC). I restored my profile folder from backup and Inbox shows my email and settings look okay. But if I try to reply to a message, TB freezes. It opens the new message dialog, but the TO is left empty and everything is unresponsive with spinning icon. All I can do is close the program.

Suddenly TB was not responding so I had to close it and restarted it. But all my tabs where gone... This has never happened before. And it's quite unfortunate, since the tabs is a kind of 'to do list' of mails I have to reply to etc. My version is Thunderbird 78.14.0 (64-bit) and my OS is Ubuntu 20.04.3 LTS 64-bit. I have not closed TB again yet. So if there is some way to recall all those tabs please tell me!
