My installation of Thunderbird is below (ubuntu 14.04, 64-bit, thunderbird 31.7.0, IMAP/SMTP email settings). My problem is this: For some strange reason thunderbird refuses to download ALL of the messages in the inbox, there seems to be an arbitrary limit of 31 days of worth of messages. I tried to put thunderbird in "offline mode" to force it to download ALL of the messages, but that did not work. I literally am running a fresh install, so there are no extensions or anything else running. Appreciate any help as this is quite an annoying problem. thanx, D Application Basics Name: Thunderbird Version: 31.7.0 User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Thunderbird/31.7.0 Profile Directory: Open Directory (Local drive) Application Build ID: 20150511105030 Enabled Plugins: about:plugins Build Configuration: about:buildconfig Memory Use: about:memory Mail and News Accounts account1: INCOMING: account1, , (imap) imap.163.com:993, SSL, OUTGOING: smtp.163.com:465, SSL, true account2: INCOMING: account2, , (none) Local Folders, plain, passwordCleartext Crash Reports Extensions Messaging Menu and Unity Launcher integration, 1.3.1, true, messagingmenu@mozilla.com Important Modified Preferences Name: Value browser.cache.disk.capacity: 358400 browser.cache.disk.smart_size_cached_value: 358400 browser.cache.disk.smart_size.first_run: false browser.cache.disk.smart_size.use_old_max: false extensions.lastAppVersion: 31.7.0 mail.openMessageBehavior.version: 1 mailnews.database.global.datastore.id: 9fd659e9-4dc0-4d3a-91d2-03ea6032883 network.cookie.prefsMigrated: true Graphics Adapter Description: Intel Open Source Technology Center -- Mesa DRI Intel(R) 965GM Vendor ID: Intel Open Source Technology Center Device ID: Mesa DRI Intel(R) 965GM Driver Version: 2.1 Mesa 10.1.3 WebGL Renderer: false GPU Accelerated Windows: 0 AzureCanvasBackend: cairo AzureSkiaAccelerated: 0 AzureFallbackCanvasBackend: none AzureContentBackend: cairo JavaScript Incremental GC: 1 Accessibility Activated: 0 Prevent Accessibility: 0 Library Versions Expected minimum version Version in use NSPR 4.10.6 4.10.6 NSS 3.16.2.3 Basic ECC 3.16.2.3 Basic ECC NSS Util 3.16.2.3 3.16.2.3 NSS SSL 3.16.2.3 Basic ECC 3.16.2.3 Basic ECC NSS S/MIME 3.16.2.3 Basic ECC 3.16.2.3 Basic ECC
