I did use Outlook Express until my 'folders' exceeded 2GB :-( I knew it was coming but someone sent me some enormous pictures. But it was good, nice and simple but could be configured for a number of email addresses. I have never liked Outlook, too monstrous with so many unnecessary options. I then turned to Thunderbird. It was okayish but never really worked well and sometimes lost mail which it said it had sent. Now, it's simply not working suddenly with one email address. And it's now been officially dropped by Motzilla. You can't really expect support for something that's been freely developed, so I wouldn't mind paying something. Provided it's been working for some time and seems likely to continue to be supported for a number of years. So, suggestions, please, for Windows.
