Hello, I’m having an issue with Mozilla Thunderbird when using my WP.pl (IMAP) email account. Thunderbird keeps downloading messages endlessly — it repeatedly fetches headers and then tries to download all emails for offline use, but the process never finishes. I would like to keep all my messages available offline, but it seems Thunderbird is constantly synchronizing and never stops downloading. I haven’t tried any troubleshooting steps yet. Could you please advise how to properly set up Thunderbird so that it downloads all messages once and then keeps them stored offline without repeating the same process continuously?
