I just created a new Thunderbird profile. Unfortunately Thunderbird only downloads recent messages. I need to get all my messages and subfolders. Any idea?

Go to Tools/Options/General/Config Editor or in more recent versions Edit/Preferences/Advanced/General/Config Editor. This may vary between operating systems.

If presented with a

dialog, click on the button "I'll be careful, I promise!".

Type folders_for_new in the filter box.

Look for an option called mail.check_all_imap_folders_for_new or on newer versions mail.server.default.check_all_folders_for_new.

Change this setting to true. This has the effect of not treating inbox as special, but all folders are "inbox", so all folders will be checked and downloaded.

If this key does not exist, then add it (right click / new) exactly as it is written above as a boolean preference. When you add the preference, you will be asked for the initial value. Choose true.

Next, in Account Settings/the account you are referring to/Synchronisation & Storage ensure that "Synchronise all messages locally regardless of age" and "Keep messages for this account on this computer" are selected.

There is no mail.check_all_imap_folders_for_new in current version of Thunderbird. –  Damian Nowak Mar 29 '13 at 22:05

In my recent thunderbird, the Config Editor button is in Edit->Preferences (from the menu) then Advanced->General tab (ie: General tab in the Advanced section). Config Editor is a button at the bottom right. –  drevicko Apr 3 '13 at 3:18

@Paul, oh, thanks for updating, I didn't realize I just have to create it. –  Damian Nowak Apr 4 '13 at 12:08

there should be a menu or button to "go offline"

in my current thunderbird - 17.0.2 (in ubuntu 12.04) the button is at the lower left corner of the whole app -

clicking it will start the download and if everything is configured - for instance mine has "keep all messages regardless of age local" then that is what it will download

This is the key. Hitting the button in the bottom left corner will take you to offline mode and will give you the chance to force Thunderbird to download everything. –  Jakobud Mar 14 '13 at 22:41

You have to check a box called "Keep messages for this account on this computer". Have a look at this tutorial for keeping IMAP messages in thunderbird.

This option is already set. The main issue is that it doesn't get subfolders. –  salman.mirghasemi Nov 5 '11 at 18:20
    
Have a look at the tutorial, they write about this, too. –  Jens Erat Nov 5 '11 at 18:22
    
I read that part as well. It seems that Thunderbird is not able to see subfolders. I am going to try with another mail client. –  salman.mirghasemi Nov 5 '11 at 19:34
