If there is one thing I have always disliked is 'email migrations. When deciding to switch from Thunderbird to Outlook for the MBOX data of 2024-25, I was expecting to face a really annoying and long process. But surprisingly, it wasn’t. Here’s what happened.

I began by defining tools that would help in the transition to be smooth. Out of trying many options, I found the WebbyAcad MBOX converter software. It appeared to be reviewed and featured well, so I said let me try it.

The general preparation was very simple. The tool was downloaded, and I imported the MBOX files and then chose PST as the file type to save my results. The best part? It was having the ability to batch convert something, which would have taken me hours to do.

As soon as I clicked on “Convert,” I could hardly believe how fast a work of it was. That is an undeniable advantage – every mail, folder, and even attachment was intact. I did not even delete a single file, which was way faster than I anticipated.

That which I had probably estimated to take days, was actually achieved in minutes. These new PST files are quite compatible with Outlook 2024 and I had no problem at all trying to access all my data.

If you find yourself in a similar situation, there is a solution; email migrations don’t have to be a headache. There shouldn’t be any hitches if you get the right tool. In doing what I thought was an impossible mission after research, the WebbyAcad MBOX email migrator made it easy as pie.

Hello, I am planning to do a fresh Linux install and in this context I also want to setup Thunderbird completely new, starting with the default settings. However, there are two things I would like to backup and restore (export and import).

1. The information which emails I have explicitly labelled as "Junk"/"No junk"
2. The information from which domains I allow loading remote content

I think this makes a lot of sense because I can setup my accounts easily and the mails, addresses and calendars will be synced from the cloud, and view configuration is no big deal either. Only that kind of "user data" that was gathered over several years is something I want to hold on to, and be able to continue to use. Is this possible somehow? I am not afraid, e.g., to manually copy individual files from the profile folder, if that data is stored cleanly separated somewhere. Kind regards, Chris

For some reason, I was obliged to change the password on one of my external email box. I made a mistake creating a new mail box in Thunderbird with the same name and the new password, instead of just informing the new password on the existing mail box. I have now two mailboxes with the same name in Thunderbird. One is enough, but I can't find the way to remove / cancel the second one...

Thank you for your help

I've found that some of my emaIls in very latest Thunderbird mail client on Windows 10 have had their content replaced with a phishing email - the title of the email is as per the existing email received yesterday but the content is a phishing email made to look like a contact request from a motor insurance provider that I used years ago and the email is addressed to the email address I used when dealing with said insurance company.  It's only an issue with Thunderbird as the email looks fine on my mobile phone and in Outlook.  Either Thunderbird itself is compromised or one of the installed extensions is compromised.

Has anyone come across a similar issue?

I'm running an antivirus scan but I think I might uninstall and wipe clean Thunderbird if the scan shows no issues.

Hi I've just realised that Thunderbird has been deleting inbox messages from server with IMAP server setting. Is there any way how to turn this off? I would expect this to happen with POP but not with IMAP. Cheers Mike

Dear,

I have a problem with sending emails via Thunderbird desktop platform. Namely, I have set up a Yahoo account, and set the SMTP authentication method to OAuth2, however I still have the issue with sending emails. There's no problem with receiving emails.

Can you help me please?

Hi all,

I just set up an email account with POP3 at Thunderbird and enabled leaving messages on the server for, say, 30 days. But if I enable this, all messages stay on the server. I have tried this using my Gmail account, Office365 account, and another provider's email account, but the result is still the same. Do you have any suggestions for this case? Or am I missing any setting?

The reason I need this feature is because I use an email provider with a 2 GB email space limit. I want only the past 30 days of messages that are still on the server to avoid email space being full, meanwhile 30 days at the server to allow user still able to read the past 30 days of email from their mobile phone or web.

I read on the internet that if I go to Mail then the body of the email should be available when blank in above subject files/folders. This does work, but it has only just started happening. Internet information says due to out of date apps, does this mean Thunderbird is out of date and needs updating because usually the updates are automatic? Or does Thunderbird need to look at the problem and fix, I shouldn't have to go to Mail each time an email body is blank. Not all emails are blank. Appreciate your assistance.

Can this be doctored to send via Thunderbird? If so pointers would be apreciated! Sub FredWeeklyReport() Dim OutApp As Object

   Dim OutMail As Object
   Dim MyAddress As String
   Dim MyAddress2 As String
   Dim Response
   Set OutApp = CreateObject("Outlook.Application")
   Set OutMail = OutApp.CreateItem(0)

   On Error Resume Next
   
   Response = MsgBox("Fred. Hide all invoices, check worksheet is up to date", vbOKCancel)
   If Response = vbCancel Then GoTo ExitLable
   'Worksheets("Sheet19").Visible = False
   MyAddress = Sheets("Work summary").Range("Eddress1").Value
   MyAddress2 = Sheets("Work summary").Range("Eddress2").Value

   With OutMail
       .To = MyAddress
       '.CC = MyAddress2
       .BCC = ""
       .Subject = "Fred - PM - Weekly report"
       .Body = "Attached please find my weekly report. Regards, Peter"
       .Attachments.Add ActiveWorkbook.FullName
       'You can add other files also like this
       '.Attachments.Add ("C:\test.txt")
       .Send   'or use .Display
   End With
   On Error GoTo 0

ExitLable:

   Set OutMail = Nothing
   Set OutApp = Nothing

End Sub

Out of the blue, my Mozilla Thunderbird emails quit coming in. I paid a guy to get 2 weeks worth of emails to come in and thought the problem was fixed. Next day, same problem - no new emails coming in. What is happening? I need help.

I am unable to send any messages. Getting this error message - An error occurred while sending mail. The mail server responded: Resources restricted from 69.115.218.69 - try again later (AA,31).

It will list whatever address I am sending to or one off of a group. If I delete the one address it lists out of a group I get the same message with a new address cited.

Any suggestions?

Constant blue circle timeouts when trying to open emails or send. Everything stops while the blue circle of death throbs for up to 30 seconds every time. Makes every email sent and every one marked junk or otherwise take forever.

Help.

Hi I am syncing contacts between iCloud and Thunderbird and in most aspects it’s flawless. However when I change or create a contact in Thunderbird there seem to be a problem in character encoding. When I view the contact in iCloud the swedish characters åäö are replaced with som random strings. The other way around works as it should.

Does anyone recognize the problem and perhaps have a solution? Thanks.

While cleaning up email to get rid of the large amount of junk I sort by correspondent. This allows me to select several of the mostly junk emails together to delete them. I highlight the first email I want to delete, go to the last one and hit shift and click. Sometimes that can be over a hundred or so emails to delete at once. After selecting delete, sometimes they don't all delete. The email is no longer bolded as though I had read it, but only a portion of the selected actually delete. It sometimes takes 2, 3 or more times of selecting them to get them to all delete. This has just been recently, within the past few months that I have noticed this. Not a terrible problem, but curious as to why this happens.

Starting about a year or more ago, when trying to set up profiles on Thunderbird for a comcast.net email address, it would fail. The different errors generated would indicate it was a problem on the mail server, and not with thunderbird. Even comcast support couldn’t figure it out. With trial and error, I finally did. - Enter your name, address and password in the setup screens and allow it to get to the “configuration found” menu. - Select to configure manually. - Under incoming server for IMAP, Authentication Method will show 0Auth2. Change it to normal password. - For Username, it will be set to the entire email address. Remove the “@” sign and everything to the right of the “@” sign. So instead of email@domain.com it will show “email” and that’s it. - Under outgoing server for SMTP the authentication method will show 0Auth2. Change it to normal password. - If username shows the entire email address, (It shouldn’t, if you changed it for IMAP) then remove the “@” sign and everything to the right of the “@” sign. - Click the Re-Test button and it should pass. - Click the Done button and the setup should be completed with no issues. -
