Thunderbird Community Forum

I have two email addresses on Thunderbird: [redacted] @gmail.com and [redacted] @gmail.com which I use regularly. Recently, when trying to open these accounts, I have found that I am unable to do so but that when I click on the Thunderbird icon, I get a mall box with various symbols on it, none of which helps to open my inboxes. Your assistance would be much appreciated and my mobile number is [redacted phone# from community support forum] Thank you, David Beglan.

Hello; I have been using Mozilla Thunderbird for many years on my PC and was wondering if I can start using my account on my Ipad or Iphone as yet?

          Regards

Yesterday I downloaded 90 emails from my mail server. Only 5 of them were filtered correctly.

Upon reviewing the remaining 85 emails, I observed that many of them "should" have been filtered. So I opened up the Tools - Message Filters and applied the filtering to the INBOX file.

Almost immediately, all 85 emails disappeared. They were not in the Trash folder, nor were they visible in any other folder or mail box that I could see.

It was recommended to apply the "repair" to the INBOX which I tried; However, all that happened was 318 older emails that I have processed a few days before reappeared in the INBOX. Which interestingly would not sort by the date indicated for the email; they would only sort by subject and sender.

It was further recommended to close TB, and delete the INBOX.msf file. Which I did do. In addition, I also restored the INBOX to the previous days file using my daily backup files. That file shows 101,076 kb of info contained in it.

I reopened TB to find once again nothing in the INBOX, and when I tried to re-run the get msgs aspect, the result was the system telling me there were no email messages to collect.

Yet I know the same 90 emails are still sitting in the mail server system.

Why did this happen?

Where did the 85 emails in the INBOX go to?

Why isn't the set of 2200++ email filters not automatically filtering all emails once they are collected, and distributing them to the appropriate email file folder / mail box?

What recommendations are available to help me resolve this situation and prevent it from happening again?

Also, I have a txt and html file of the 8 Jul 2026 filter report. Why can't I upload said files along with this set of information? Why are attachments only restricted to image files?

Thank

I am trying to connect my Outlook email hosted by Godaddy so I can send/receive on Thunderbird. Godaddy said that the problem was on Thunderbird's end. I have attached the error message that pops up when i try to load email. E-mail is mike@watershedguardians.org

Thank you!

I have attached a screenshot of the retention settings for the Gmail All Mail folder. This folder contains emails that have a date nine years ago. Can you tell me if I did something wrong in the retention settings?

I thought earlier today it was using the retention settings but I just checked and it is not.

I recently bought Windows 11 a Friend loaded 11 and Thunderbird for me! Not all of Thunderbird transfered, I'm missing 8 t0 10 separate folders and all of my Email address! Can you help me! Thanks Danny Dimperio

Topic: My ignorance! Working side by side with my bank account 1/2 size, and 2 columns of my inbox screen 1/2 size worked great! A job well done! Re-sizing TB screen back to normal size caused a large blank screen, headed "Inbox", with only a couple of blank columns, no folders, no Sent, no Trash, and it is unresponsive. I went out and back in and it is the same. I didn't do anything unusual. This is a fairly routine action. Please can you help?

I have an issue when trying to forward an email that contains an attachment. I receive the following error message:

"Sending of the message failed. There was an error attaching the file. Please check that you have access to the file."

I am using Thunderbird version 152 on Windows 10 Pro.

This issue only occurs when forwarding emails with attachments. Other email functions appear to work normally. Has anyone else encountered this issue? I would appreciate any help or suggestions. Thank you in advance.

When I'm in Calendar, I see a certain time interval, depending on screen size. In the first example below, it goes from 07:00 to 21:00. When I toggle between Calendar and Email tabs (using shift+tab or by mouse-clicking) and back to Calendar, the time interval now shows 06:15-20:15. (second image) If I toggle once more, it starts at 05:15, and so on, it goes back one hour after each toggle, until it reaches 00:15. This is very annoying because I have to constantly toggle between Email and Calendar, so the Calendar is more and more shifted and I have to move it manually to keep working. I haven't seen this bug described before. Do other people experience it? Any solutions?

Thanks, Franck

Hi,

I use Thunderbird 152.0.1 (64-Bit) and I only have three items in the files & attachment section of general settings (JPG, PDF, Excel). How can I add more items, for other file types? Is there an easy way to do this or does this mean I have to deep dive into the configuration of Thunderbird?

And would it be possible to add an item to declare that website links in e-mails have to be opened with Firefox in private mode, which is not the standard browser on my machine?

Thx!

Recently my HP PC crashed, and since had its old hard drive updated to a new solid state drive. Basically I am lead to believe is was a problem caused by a security update from Microsoft. My old system was Windows 10, now updated to 11. A copy was taken of the old drive and I was advised that all of the apps etc could be accessed from a folder on my desk top. Not really the case at all. In the mean time I have manually added back all the apps etc that I would have been using. OK, my question is, I have downloaded the email account and set it up OK. Is there any way all of my old stored emails and folders can be restored and copied to my new OS. If not, I can survive. Probabley a good idea to loose some of the old data. Thanks in advance

is there any way old emails can be retreived after deleting them to the bin. I thought sending them to the bin folder still retained them in archive status, but trying to look back more than the 3 months current in & out boxes They don't appear to be there

As per the title. I have allowed external content for one message (it is disabled by default). Finding the option to do that was easy, because there is a specific message with a drop-down menu to configure access to external content for that particular message.

However, now that I have allowed external content, I do not wish to keep it allowed (no need for external parties to know when and where I open and re-open and re-re-open this e-mail). The drop-down menu to manage the privacy options for this particular message has disappeared. That is inconvenient, to say the least, because I can't see any other way to get to those options. What am I missing?

I am trying to add a new identity, I already have 3, so perhaps there is a limit? I have created the identity under manage identities with no problems. However, the new identity does not appear in Thunderbird, where the others are. The address is not recognized, and does not receive emails. I feel like I have missed a fundamental step but have followed the help instructions & cannot see what I am doing wrong. Ive checked and the program is up to date. I hope someone can offer advice thanks Anne

I need to use the offline MBOX folders of several email accounts that I access via IMAP to migrate the contents to a new provider. There are no files in my Thunderbird profile directory tree with the extension .MBOX (under Windows 11) but I have some fairly large files of the form: <Thunderbird profile>\ImapMail\<IMAP server>\INBOX and <Thunderbird profile>\ImapMail\<IMAP server>\Sent are these the MBOX files? Can I safely ignore the .msf files? A further problem is that I have more than one account on the same server, but the second account only appears as: <Thunderbird profile>\ImapMail\<IMAP server>-1\INBOX and <Thunderbird profile>\ImapMail\<IMAP server>-1\Sent How can I identify the corresponding e-mail accounts?
