Hello and Help Please! ;-) I need every email from my IMAP account stored locally but Thunderbird is not cooperating. I'm unsure if this is a settings issue or an ISP/network issue. I'll explain what happens and what my relevant settings are. I'd be immensely appreciative of any help. It's been three days since I installed Thunderbird 31.2.0. It still has not downloaded all of my emails. It reattempts downloading if I click the blue icon (on-off line) in the lower left hand corner but after several minutes of downloading, it just stops responding. It does seem to have downloaded all of my folders, though. I’ve completely uninstalled and reinstalled Thunderbird and my profile to no avail. Does anyone know why this is happening? Apologies if I've overlooked an obvious solution, but I implemented every sugestion I found here by the issue persists. Again, I’m running TB 31.2.0. I'm on W8.1 with a 55 Mbps down/13 Mbps up connection. The total email account size is approx 3GB with 200 folders. SERVER SETTINGS Show Only Subscribed Folders (Unchecked) IMAP-mail.outlook.com / SSL/TLS / 993 SMTP-mail.outlook.com / STARTTLS / 587 Check for messages at startup Check for messages (every 10 minutes) SYNCHRONIZATION & STORAGE Keep messages for this account on this computer Sync all messages locally regardless of age DISK SPACE Don’t delete any messages Thanks!
