Hi there, I've been a Thunderbird user for almost a decade now and have had a problem that's been bugging me for all these years and I thought maybe I should finally investigate. I use Thunderbird with my Hotmail account and have the setting enabled so that it leaves messages on the Hotmail / Outlook server (which is what I would prefer). Because my account is so old my inbox is massive, I started sorting messages, particularly large ones, into year-based folders, to keep my inbox folder sizes down in Thunderbird. I would prefer to just delete the emails and not have to keep them (most of the "large" stuff I would sort is stuff I'd much rather delete) but I can't because a day or two later (sometimes DAYS later) Thunderbird will redownload the email I tried to delete, thus taking up even MORE space. Is there a simple solution to: - Have the setting enabled so that I keep my emails on the Hotmail / Outlook server AND - Still be able to delete messages from Thunderbird without Thunderbird re-downloading them? Any help would be appreciated - thanks!
