Thunderbird--All of my current year INBOX emails disappeared. I have tried repairing the folder, deleting INBOX.msf and restarting including in troubleshooting mode, reinstalled Thunderbird. None of these actions changed the situation. Is it possible to retrieve these messages?

The INBOX folder is much larger than the INBOX.msf folder, so I'm thinking the message info is in there?

I;m using Windows 10.

A few days ago I lost all of my saved email messages, plus "sent" emails, and "deleted" emails. I had important information stored there for future use. I am hoping to be able to retrieve it. Any help would be appreciated. Thank you!

I have several emails (personal and business) that I use and have them grouped in Unified inbox. Recently one of those emails showed up as a new folder (just under Trash folder) in bold type. It has with a varying number of emails in it, now 18. When I click on the 'open folder arrow', a subfolder 'Archives' with nothing in it shows up. When I open the email folder a new page appears with the email as a header and underneath 'set up another account', 'import from another program', 'about mozilla thunderbird', and 'resources'. What is happening? How can I get rid of this folder since I can't read any of the emails in it and it is just a duplicate of the folder that already is working find in the inbox? TIA

I use apple mail on my phone and Thunderbird on my PC and my (IMAP) email provider is GMX. I recently added a couple of sub-folders to an existing folder and changed the names of couple of others (in the same main folder). I did those changes on my phone. However, those changes are not reflected on my PC. The folders with changed names are in the folder list but greyed out but the new folders are missing. If I click on a greyed out folder it is empty. I've tried several ways to force the list to update but, so far have been unsuccessful.

What is causing my problem and how can I fix it?

Thanks for any advice.

I just wonder why all mails suddenly seem to be totally disappeared. Without any warning. Althoug there should be 20 mails (which figure has only been creasing for the time being/already for hours. :( Also all ready models/musters seem to be deleted. So I can't add my usual signature as easy as usuaylly:

I've tried setting up Thunderbird archiving according to the documentation to save archived messages locally, and in the same hierarchy they had when I archived them. That is, if I have:

INBOX

   Box1
   Box2

... etc. then archiving would create a parallel structure in Local Folders

However, this isn't working.

I select "Keep message archives in Other (Archives on Local Folders).

For "Archive Options" I select "A single folder", "Keep existing folder structure of archived messages" and "Recreate inbox folder".

However, when I archive something, Thunderbird just creates a folder "2026" (this year) and puts the message in there.

Why are my settings NOT working?

Hi all — I’m running into a persistent threading issue in Thunderbird (v.148) vthat survives profile rebuilds and affects only specific conversations.

Symptoms Some threads show the expand/collapse carrot normally.

Other threads (same accounts, same folders, same time period) do not show the carrot.

The pattern is consistent: the same conversations fail before and after a full profile rebuild.

Both Inbox and Sent show a mix of threaded and unthreaded conversations.

No global setting seems to be wrong, because most threads work correctly.

What I’ve already checked mail.strict_threading = false

mail.thread_without_re = true

View → Sort By → Threaded

View → Threads → All

Folder Repair on Inbox and Sent

Full profile rebuild

Re‑added all accounts

Rebuilt .msf files

Verified that threading works across folders (Inbox ↔ Sent)

Verified that threading works across accounts

Verified that threading works for most conversations

Header checks For the conversations that do thread, headers look normal.

For the conversations that don’t thread, the headers also appear normal:

Message-ID: present

In-Reply-To: present

References: present

No obvious corruption, malformed IDs, or missing brackets.

What I’m trying to understand Why would Thunderbird:

Successfully thread most conversations

Fail to thread specific conversations

Preserve the same failures before and after a rebuild

Show carrots in Inbox but not in Sent for the same conversation

Show no global misconfiguration

Is there a known edge case where Thunderbird rejects a thread even when the headers appear correct?

Are there hidden rules about ambiguous References: chains, multi‑server storage, or cross‑account BCC workflows that could cause this?

Any insight into how Thunderbird decides not to show a carrot would be appreciated.

Thanks in advance.

Does TB have a "complication" that I can put on my watch face? Most modern watch faces have slots for data provided by app developers like number of pending messages. Does TB have a complication for watch faces.

Hello,

I've moved last week from Microsoft Outlook from Mozilla Thunderbird on my MacBook Pro laptop for managing my e-mail accounts.

I've added an Outlook account (e-mail xxx@hotmail.com) to Thunderbird. However after using Thunderbird a few days I've discovered that some sub-folders in my private folders are missing.

I've added in attachment an image showing my folders on my mobile phone (using Microsoft Outlook) and an image showing my folders on my laptop (using Thunderbird where both 'Bureau' and 'Instruments & Lumières' are missing).

Thank you in advance for your help.

Best regards, David
