Thunderbird Community Forum

I tried to get a copy from timemachine (backup) and it complained that the profile is from a newer version. TB is full of bugs and horrible UI "features" that suck - simple things like changing column width for example.

Dear Thunderbird team I am an avid user of TB (home desktop Windows PCs), but I have been resting on my laurels on v78 for a few years now. I know, shame on me. I would like to upgrade to a stable "modern" release (emphasis on "stable" please). Can you please advise if I should aspire to end up on 115 or 128, and how I might get there ? From reading some older blogs, there is advice that says.... first go to v91, then v102, then v115, and so. That seems a bit tortuous, but I am happy to do so if that is still the recommended approach.

Also, can you advise on how I manage my Profile through all this, do I need to do various exports/imports as I move through these different versions, etc.

Many Thanks

Why is changing column width so complicated and buggy under 128.3. Nebula on Mac?

simply want to enlarge From column - before Nebula - just do it. Now, pain in the back - only lets you do a bit and moves everything else and still doesn't let me do what I used to do. What a mess they made out of a great program !

Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.

I have two iCloud mails in Thunderbird. The older one runs great. For the other new one - same settings - mails sent often appear totally blank in the sent folder. Going to the iCloud webmail, sent messages appear totally normal and mails are sent to destination without any problem. I tried everything, no avail. Also weird is I have two "sent" folders (for no clear reason). Both have this issue, not always. See screenshot of iCloud webmail.

I am getting these messages when trying to reply: mail.iinet.net.au587 and Sending of message failed. Peer's Certificate has expired. The configuration related to must be corrected. I would like to know what to do to correct this.

Searching calendar events in Thunderbird used to search both title and description fields. For example, if I searched for "dental" it would find events titled "Dental appointment" and also events with "dental" somewhere in the description field. Now it only seems to search the title. I've always put most of the information in the description field, and I use the calendar primarily as a diary record of my life and things I need to keep track of, so this is a major downgrade in terms of usability for me. Is there any way to still search the description field?

Why can't I retrieve a website that I am directed to in a Thunderbird email? Usually the website is in "blue" and can be retrieved by a simple click, these are just in black.

After the 128.3.0 update nothing in my email works. I can't send or receive emails. I wrote and email and since it wouldn't send I wanted to save it and could not save it. Initially I got the message that my email accounts were black listed. That stopped and I got another error message that kept repeating itself. I am not sure what that said anymore. I rebooted my computer and now it just doesn't work. I checked my settings and they are still correct.

Is there any way that I can go back to the last update? Is there anything I can do to fix this one without losing all of my saved emails? I am using Windows 11.

I am maxing out my Comcast email space allowance (10 gb) and want to move it all to my PC. (i don’t want an encrypted backup, but something readable.) I thought I could use Thunderbird and set up a POP3 account on Thunderbird with the option to leave emails on the server. It downloaded only the Inbox, not the subfolders. I read on the Forum that that is what happens with POP3. My understanding of IMAP is that I don’t get the actual email on Thunderbird, because it stays on the Comcast server.

Is there a way to download all those emails and folders to Thundebird (to keep) and then delete them from Comcast? I don’t plan to use the Thunderbird client for my day-to-day email, simply to store the last 10 years of email.

I have tried to research the forum articles so that I don’t bother anyone needlessly, but can’t find an answer. Thank you.

I already tried putting Thunderbird as a shortcut into the C:\Users\<myAccountName>\AppData\Roaming\Microsoft\Windows\SendTo (aka. shell:SendTo) folder. But when I use the "Sent to" menu and select Thunderbird, the file to be attached just gets openned by Windows as if I had double-clicked on it. Thunderbird does not even open a new message.

I also tried changing the call of the Thunderbird shortcut in the SendTo folder to: "C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -compose attachment= At least, then Thunderbird opens a new message. But it just writes the path\filename of the file to attach into the attachment section. When I then try to send the message, Thunderbird says it cannot access it under this path.

How are you doing this? Thanks!

I have five email accounts defined on a hosting service. On my computer in Thunderbird I have my main account on the left side followed by one of the other five. Then comes Local Folders and two more email accounts. I can retrieve email into my personal account and the one above Local Folders. I can't retrieve into the other two accounts. My wife's computer has HER personal account and one of the ones into which I can't retrieve. She can't retrieve into that one either. I have checked details of the definitions of the accounts on the hosting service and in Thunderbird on both of our computers and can't find anything different on the accounts that don't retrieve mail. I have an Android tablet running the K9Mail client and have my personal account and one of the problem accounts defined. I setup the other problem email account there and got complaints about it not being from a trusted site. I went ahead anyway, went to my personal account and sent a message to the new problem account and was able to go to that account and retrieve the message. What am I missing?

Hi everyone,

Im doing a clean install and i dont want Thunderbird to sync and download some emails.

What im trying to achieve is to download every email to use offline and be in sync with the Gmail account but only the most recent ones. And i did this:

Inbox: So far in Gmail i moved alot of emails from the Inbox to another folder. How can i disable that folder to sync in Thunderbird? Because as soon as i log in, every folder starts to sync and download automatically.

Outbox: I did some research and its seems that is not possible to move emails from outbox to another folder. Is there any way that i can only download emails only after specific date?

in the older TB for a loooong time, adr book and inbox showed up under WINDOW item new TB changed that and sometimes shows under TOOLS menu but in inbox it doesn't in compose/edit window it shows. See attached

I have been trying to get my Comcast email configured for days with no luck. When I try to log in using my Comcast password I get a screen that shows "Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server. Reference #18.321c2e17.1727662977.283cff2b https://errors.edgesuite.net/18.321c2e17.1727662977.283cff2b. I have allowed access to third party apps on my Comcast account and I am able to access my email on the Comcast website with no problem. I saw something about disabling IPV6 but it said to go to Preferences or Options in the Settings menu. My version of Thunderbird (latest) doesn't have these menu options. I have tried various IMAP and SMTP Port settings I found on the internet and nothing works.

What are the settings for Comcast email in Thunderbird?

Hi. I keep trying to delete messages from my AOL IMAP inbox, and they do go to the trash, which I then delete. But then the messages all return to my Inbox. Is this an AOL issue, or a known issue with Thunderbird? Any solutions?
