Thunderbird Community Forum

I have used thunderbird for many years and was always very pleased with how easy it is to search for old emails, using just about anything--an email address, a word in the subject line, or anywhere else. Lately, it no longer finds all the message for a simple thing, like an email address. Has something changed?

Also it seems that copies of my emails are not necessarily kept locally in that it often says it has to download my messages off the server, which can take a bit of time. In the past it has only downloaded new messages, but now it seems to download everything.

All this leave me with the sinking feeling that my whole online record could disappear at any minute. Any ideas?

I did Edit - Find - Search Messages and then Edit - Find- Global Search and searched for messages. Now all the e-mails in my Inbox disappeared. What can I do? Thank you.

I have a lot of emails stored in different local folders. My search now hang. They go so far than just hang. Is there a way to rebuild the complete indexing for my thunderbird install?

Thunderbird 147.0.1 (aarch64, macos, m2)

Team, After spending many many hours creating 14 search-folders that can find all of the right emails in approx. 20 "real" (local) folders.

Then I renamed 10 local folders and noticed my searchfolders disappearing!?

Big panic. Now, only the last 2 created searchfolders where there. The rest was gone. Realizing that the searchfolder config is in a file called "VirtualFolders.dat" I instantly took a copy. Restart Thunderbird: Now only 1 searchfolder was left. The copied virtualfolders.dat file still had 2 searchfolders in it but the rest is gone. There is no other copy/backup of this file.

These search folders are the only thing that generated some sense in gigantic piles of email.

Does renaming local folders KILL Virtual/Search folders?

Whenever I try to search my various emails for some text, at least 40% of the time it shows me the attached message. I'm on Version 149.0.1 but it's been happening ever since I installed Thunderbird (maybe 4 or 5 months ago?) My first move is to check that I haven't mis-spelled the word I'm looking for (which I usually haven't) and I definitely know that the word is valid for one or more emails. So why does this message keep appearing?

Previously I'd been running an old 32-bit version of Thunderbird (which I don't have installed any more) but I don't remember ever seeing this with the older version.

Hi, Thunderbird search as we know is and always has been megabroken. I search for "4.91" and it does not find anything even though there are e-mails with that string in subject and body.

Isn't it about time to fix it?

I have a folder that is set (via a quick-filter) to show only unread emails. Now when i mark an email as being read, it stays visible. Well, at least until I swap folders or toggle the filter on/off/on.

Why is this? Other email clients directly hide these emails.

When I search for a name in Thunderbird mail e.g Lennart, nothing from 2026 comes up, only older mails from 2025-12-31 and backwards. if I search on his e-mailadress, e.g l.name@ppost.se it finds avery mail. What is wrong?

I don't like the NEW Thunderbird, especially the Search function which is very frustrating and difficult to work if it works at all. the old one was much better where we could indicate filter elements and retrieve the emails we wanted! Is there some magic or secret methods to make this NEW one work?

Hi,

I do like Thunderbird but there are a couple of things that i'm finding it frustrating to work with and wondered if someone could provide some help?

So I use quite a lot of nested folders, sometimes up to 5 levels deep to keep things organised. Eg:

I a sub folder structure like so:

Trips - -Asia 2025 - - - -Hotels - - - -Flights - - - - - -International - - - - - -Domestic - - - -Parks - - - - - -Park 1 - - - - - -Park 2 - - - - - -Park 3 - -Europe 2025 - - - -Parks - - - - - -Park 1 - - - - - -Park 2

I'd like to be able to be able to select a top level folder (such as Asia 2025) and see all the messages in it and all it's subfolders. Effectively ALL the emails relating to the trip. Is there a way to achieve this?

Second issue: I have a saved search folder called Flagged. Right now I have to edit the properties of the saved search, then click "Choose" and manually tick each folder / sub folder I wish to show flagged messages for. I know I can select the first, select the last, press spacebar to toggle those folders. But it doesn't expand subfolders, and it means that when I add more folders (which I do very very often), I have to remember to manually update the list of selected folders (on 2 machines too as i have this account set up in 2 places). Is there a way to just select a parent folder (in my case i'd like to just select the account itself) and have it automatically include everything below that. Then I don;t need to update or change it as my folders change.

Surely both of these suggestions are sensible and would increase the usability of Thunderbird.

Also, how can I find out what folder a message is stored in from the message in cards view, the message detail panel itself or the right click menu of the message card?

Thanks, Neil

I feel so incompetent regarding this because I feel it should JUST WORK, but for me it just doesnt...

When searching for a name/date/etc in the top right search bar I typically get no result or unusable ones. Obviously this is a problem when I dont know where a particular email may be.

When I use the search messages window from my root folder, the one that gives more flexibility ie; match any, subject,contains, etc...i also get no results. For example a message that is currently an open tab in TB cant be found by that search messages window. its still searching and i began the search before I started writing this question...

When in a folder or sub-folder, the quick filter search feature works as expected.

I've checked all the places i could imagine that might govern global search options that might change this critical seeming lack of functionality and have found none.

Is this a true limitation or am I just missing something ?

thanks for your consideration- q

When I reconcile my checking account each month, it's handy to be able to search my e-mail for the amounts of transactions that I can't identify by name alone. Gmail allowed me to do this. Thunderbird, for some reason, doesn't. Anytime I search for a numerical value (e.g., "36" or "9.58"), Thunderbird returns no results. Why are numeric strings not searchable? Is anyone working on this deficiency?

how to retrieve, via search, received messages in Thunderbird? when using search it only supplies me with those message which I posted myself, but these I received.

When I search for emails and click on a message from the search results, I receive an error message saying “Email not found”, and the email body does not appear. However, if I open the same email directly from the Inbox without using the search function, the email content is displayed correctly. I would like to be able to view the email body from the search results as well. Are there any known causes or possible solutions for this issue?

Prerequisite: This concerns behavior after migrating Thunderbird email data from an old device to a Windows 11 PC. Currently, I am only using Thunderbird for viewing emails.

On doing a search for mail ... it returns a number of mails ..... but many of them when I click on the entry it comes up with 'no message found'

Is there some index I need to rebuild or similar ?

Went to search for someone in the Quick Search and it did not bring up their emails in the folder, which exist as I confirmed by sorting alphabetically and finding them. Why is this?

Hello Thunderbird team,

We are an organisation that recently migrated from another email client to Thunderbird. Overall the client has been fast and easy to use, but we have identified a key functionality gap that impacts our day-to-day operations.

Previously we relied heavily on the ability to search not only in email body text but also inside PDF attachment contents (e.g., specific keywords within attached PDF files). In Thunderbird this capability is currently missing, existing search and add-ons (e.g., Expression Search – NG, etc.) do not index or find text inside PDFs.

This feature is critical for business users that need to locate emails based on text inside attachments. We would like to request that full-text search of common attachment types (PDF, Word documents, etc.) be considered for inclusion in a future Thunderbird release, ideally with options for indexing and performance controls.

If this is already on the roadmap, we would appreciate any guidance on how to enable it or track progress. If not, we would be grateful if the team could evaluate this enhancement.

Thanks for your work on Thunderbird and wishing you a happy new year!
