Thunderbird コミュニティフォーラム

Good morning,

I’m reaching out because I’m having trouble with my Thunderbird email and need some assistance.

I was using Thunderbird without any issues before, but now all my old emails have disappeared. I can still receive new messages, but I’m unable to send emails like I used to. I also can’t recover or view any of my previous emails.

It seems like something may have reset or become corrupted, and I’m not sure how to restore my old messages or fix the sending issue.

Could you please help me get Thunderbird working properly again and recover my old emails if possible?

Thank you for your support.

Dee

I've had a Thunderbird email account for years. My laptop quit, so I've set up the account on a new laptop. I discovered that I hadn't saved my Thunderbird password, so I followed the procedure for "forgot password". This included a new p/w, and I also got a Mozilla PIN (for future Microsoft Password Manager use), and got a Mozilla Account Recovery Key, again for future use. But I can't log into my Thunderbird account. I get the message "Authentication Error" (Wrong p/w, email, etc.) Changing IMAP / POP settings didn't help, though I did go with the recommended IMAP setting.

Any suggestions?

Hello,

I'm currently using the thunderbird client to open a zoho mail account. I've set several filters (around 40) so that incoming emails are automatically redirected to the appropiate folder. If I click on the download/refresh icon (the little cloud with the downwards arrow), new email isn't received. On the bottom, a small message appears ("No new messages on the server" or something like this). You may think that that is precisely because I don't have new emails but if directly go into any of the folders and once again click on the download/refresh icon all of the emails that were supposed to go into that particular folder appear all at once (even mails that are 2 or 3 days old). Now every day I have to go into all of my 40 folders and click on the refresh button.

I look forward to your help. Kind Regards.

My Sent folder is empty, but I did not empty it. Test messages are not being saved in it. I tried making a Sent folder under Local folders and directing Sent items to it. They do not arrive there, either. What may have gone wrong?? email me at [redacted from public] @alum.mit.edu

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.

As of a few weeks ago, none of the links on the Add-ons Manager Details pages in my TB 152 work, e.g. Author or Homepage. Moving the mouse over them, left-clicking on them, right-clicking on them, no effect at all. Which is annoying, as with several add-ons I use I'll want to go the add-on's Github page to look for new betas, report issues etc. Those links all used to work, opening the linked page as a tab in Thunderbird, but now they don't work at all, not even a right-click menu option to open in browser. Still not working in 152.0.1. This isn't only with me, surely?

Thunderbird is not responding. Xfinity is working just fine I need help resetting is there any way I can speak with a person? I am totally bogged down caring for my partner with dementia. I am able to go to my settings, etc.

I have an hotmail.com account with no problems whatsoever while logging into Apple Mail, G-Mail etc. but when it comes to Thunderbird it does not let me login. I tried to login first to outlook itself, changing the servers ports etc. but nothing works.

For refrence my current server settings are: Incoming (IMAP): Server: outlook.office365.com Port: 993 Security SSL/TSL and OAuth2

Outgoing (SMTP): Server: smtp.office365.com Port: 587 Security: STARTTLS with OAuth2

I cannot send messages from any of my accounts after migrating to Greenby. I have tried to setup their outgoing server as per their instructions but it does not work. They have a AI tool which I keep going round and round in cycles

After several years of working perfectly,For no reason, I am getting this message when trying to connect to Xfinity email server

"  Login to server mail.Comcast.net with username t_m_f@comcast.net failed."

I have set all Comcast server settings to the default. Going directly to Xfinity email works great . So it must be something wrong with Tbird. I also uninstalled & reinstalled Tbird. This is frustrating !!!!!!

When I try to forward email with attachment. I get a error message stating I dont have access for the attached file so every time I have to remove the attachment in the email and download the attachment from original email and attach to my email. Which is frustrating and time consuming process.

What I thick is there is storage path issue with my email setup.

Please assist to resolve this issue.

I realize this can be a macOS issue as the problem appeared when I upgraded to 26x but I'm hoping that maybe there's another way of allowing windows to be moved with a mouse. This issue appears only under tbird and not under any other Apple or non-Apple products.

The new child window(s) opens up in the default location(s).

The issue has survived several OS updates up to the current one. I switched from macOS 15x to 26x in around January 26.

Firefox does not really open any child windows that I could find but browsing windows work as expected.

I have a suspicion someone is reading my e-mails. I am using Virgin Media as my ISP and have changed the password on my account.

Is that enough to stop my e-mails being read by someone other than me or what can I do to protect my inbox, please?
