I've been using Mozilla Thunderbird since 2003.
I started using Mozilla Thunderbird on my laptop for about a year. I have never gotten a message saying that I had to delete messages. I don't know what a person would want to do with 400+ folders. I manage four email accounts with seven folders. I use special rules to sort my emails out. I use a folder for my wife's emails, CNET, Kandle business(not mine), Lottery and Campbells. I have no problems and will NOT go back to Outlook Express, which manages 1 email account.

I'm thinking of moving to Thunderird because of some problems I've been having with Outlook Express and learning that Outlook will not likely help.
My problem with OE is that I use folders to save emails until I can transfer them over to the hard drive. My problem was that my folders were 2.46gb and OE only allows up to 2gb for folders, which has really slowed OE down.
I've tried to find the info myself, but haven't had any luck. Does anyone know how much space is allowed on Thunderbird for folders?
Or, does anyone have 400+ folders and Thunderbird still work okay?
Thank you!!!
