I'm asking this question so I can post some helpful information for people wanting to create a backup of their profile.

If you are using Windows OS and you got your download from the official website: https://www.thunderbird.net/en-US/thunderbird/all/

How do you locate the correct folder to backup? The backup must contain everything, profiles, mail accounts, emails, address books, calendar, preferences - the lot. The backup can be used to transfer between computers.

Our email comes through SaskTel. They are making changes and suggest that we contact any other platforms we use to confirm they support DMARC-compliant email sending and to see if any updates are needed. Please provide this information to me. Thank You.

A message failed to send due to some issue with the mail server, and Thunderbird said I could choose to Send Later, which I chose to do. But that message disappeared (to me) - wasn't in Drafts, where did it go? Thanks,

I am not able to receive or send emails using my wifi, but can using data (same provider). I have queried this with my email host and wifi provider and both have said there is no issue on their end that would block these actions. The email host suggested I change port 465 to 587 for outgoing to see if that made a difference. It did not.

This issue is occurring on the web platform as well as the android app.

The error message in account setting is: an error occurred connecting to gsyd1001.siteground.net:993."

I'm running TB on Windows 11 on a Dell Desktop machine. It's a pretty basic installation with EE Cyber security, which is I think Norton. I've been using TB for a couple of years but recently it has almost stopped working. I notice from Task Manager that TB is massively leaking memory and consuming much CPU time. I don't think I have any add-ons and I only use TB for email. It's now so bad that I'm even unable to go into TB's Settings or Tools or anything else. I've tried creating an exclusion for TB profiles and TB.exe in the Norton. I've tried starting TB in troubleshoot mode but all to no avail. I have it in IMAP, Port 993, SSL/TLS for incoming mail and Port 465, SSL/TLS, Authentication Required for Outgoing mail. I'm currently often unable to even access mail previously downloaded to the local Mail folders, TB is just hanging with the bar in the lower right corner endlessly running along. Most puzzling of all, is that very occasionally is starts working again and then I dare not switch the machine off! It's become an indeterminate system. Please help, I'm nearly eighty and trying to organize my holiday, which is needs email to make bookings. Thanks in anticipation.

I send and receive emails on both pc and Apple devices. Only on the pc I get a message to login to closed email address. I am unable to do this. Need to remove this re-occurring pesty message. Please help with suggestions. Thank you

Hi,

I've just updated my Thunderbird for Windows to 151 and I got this nasty surprise (this is why I hate updates these days).

The message list in dark mode, in a table view, now has this awful pitch black background instead of the normal dark brown as it used to have. It looks OK in cards mode, but I don't like cards mode.

I certainly hope this is a bug and not by design. Can this be fixed, please? It looks terrible, it's hard to look at, like old Windows 10 dark mode or some high contrast accessibility mode.

Thank you!

I use Thunderbird on my desktop and since early June, I have not been able to receive any new messages but I can still send. Everything works fine on webmail (Yahoo) and phone (Samsung Galaxy), it's just my desktop which is affected . I asked Duck AI about this and this is what I got...

I tried the solutions offered without success.

No matter how large or small the Thunderbird window is, I can't see all 3 of the Address Book columns without expanding the window to take up the entire laptop screen. The column width seem to be locked in at a pre-set number of pixels. I've tried to grab the edges of the columns to reduce their width, but they don't seem to be active. What I would really like would be for the Book to adjust to the Thunderbird window's width, or at least let me scroll between the columns. As it is, I can't view or edit the entry details of a individual listing in my Book without greatly enlarging the whole window.

Any ideas on changing these column widths would be appreciated. I've got Windows 11, and TB version 140.13.0esr (64-bit).

Thanks, Grasses

I need help. How do I troubleshoot TBird asking for a password that disappears when I go into troubleshooting mode? In other words, I can enter anything in for the password, or dismiss/close the pop up box, and nothing is effected by it. I still get all me email for all accounts. The only thing at the top of the box is a user name (pmruzicka). At this point, I have deleted the accounts that used that user name, including all info for the outgoing servers (even tho this password request pops up at TBird start). I have Disabled ALL extensions one at a time and the pop up still happens. I have set TBird to default them,e - pop up still there. I have unchecked the hardware acceleration box - pop up still there. I have no clue what else I could do at this point. I do NOT have a Primary password set. Can someone please help me figure this out? Getting tired of having to click off that pw box every time I start TBird. Thanks. Also, this has been happening through the last few updates of TBird.

I have set a custom theme on my Thunderbird on Linux. As you can see by the attached image though, the menu bar is hard to read when you get to the right side. Dark background and dark text doesn't really go together. Is there a way to make the background of the menu bars a solid color or something less see-through so the text can be read? I want a light theme, but I need to be able to read the menu.

When messages arrive in inbox and are marked spam they do not auto move to spam folder. I have to uncheck the spam icon and re-check it. Not until then will they move to spam folder.

I am using Linux Mint Cinnamon 21.3 and Thunderbird POP3 email. I have 10 email accounts.

What I have noticed is the Thunderbird 128 series startup email check and/or "get all messages" is quite slow compared to previous versions.

Thunderbird 102.15.1 took only 4 seconds to check 10 email accounts, Thunderbird 115.18.0 took 5 seconds, but Thunderbird 128 and 136 series takes 15 seconds. All of these have used the same user profiles.

There is no antivirus software active. All messages are deleted from all accounts. No messages to download and checking for messages is still slow.

I have tried the Betterbird 128 series, a fork of Thunderbird, and it too behaves the same. Betterbird 115 series work fine, just like the Thunderbird 115 series.

Is this slowness in the 128 and 136 series by design?

I apologize for the subject line, but there is no better way to describe the problem....

I've been using Thunderbird for a few months now and it has mostly worked well. Then this afternoon I was reading my mail in the Unified Inbox and I noticed something very odd. I had a number of emails showing in the header list with the same "From" and various subject lines. On the face of it, that wouldn't describe any weird behavior except that I noticed the subject lines absolutely didn't match the "From" information.

As I would go to read these emails, the email itself would be correct in the preview pane -- including showing the correct sender name and email -- but the "From" information in the header list pane would still be wrong.

I'm sorry that I can't post a screenshot to make this more clear because there is just too much personal information on screen. But these emails are from several different senders, received by several different email accounts. Everything is correct except that the "From" shown in the header pane is wrong. This is very obvious to me because I normally run entirely in the Unified Inbox with the emails sorted by the "From" information

One example is an email that is actually from "U.S. Department of Veterans Affairs <do-not-reply@notifications.va.gov>" which Thunderbird displays correctly in the preview pane (where I usually read my emails) and if I open the email itself, but the header pane says this email is From "Prepper-co <joshua@prepper-co.com>"

Another example is an email that is actually from "USPS Customer Support <uspscustomersupport@usps.gov>" but the header pane says it is from "Rainier Arms <sales@rainierarms.com" < p></sales@rainierarms.com">

These two examples were received in different email accounts that aren't even on the same server. I have other emails from these same senders that are shown correctly

I found this problem while using 150.0 (64-bit), which said 150.0.1 was available, so I restarted Thunderbird and it updated to 150.0.1 (64-bit) but the problem is the same.

When I press the send icon in The Messaging Company email nothing happens. Therefore I cannot send emails. Have tried various port numbers in the outgoing server and secure connection is established.

Just want to open a 'compose a message' without the extra main window also opening.

Tried to ask AI - that was no help - no surprise.
