The Windows Live Mail e-mail client is actually really, really good. Managing accounts is simple and straightforward. Moving messages to/from accounts is a breeze. Doing simple things like attaching files, using fonts and so on is easy.

So why am I still using Mozilla Thunderbird?

One - and only one - thing in Windows Live Mail makes it suck really, really bad.

This:

Note the part of the top that states verbatim: "Note: You can’t use rules for IMAP or HTTP e-mail accounts like Windows Live Hotmail."

This completely sucks.

I can set message rules (a.k.a. filters) in Thunderbird as the day is long. I can set colors of e-mails, flags, move them anywhere I want, and so on. I can do this for POP or IMAP.

Why is it that this stupidly basic function is 100% disabled for Hotmail and IMAP in Windows Live Mail? Why only for POP based mail?

Anyone? Anyone? Bueller? Bueller?

Ready for the real kicker?

You can use Message Rules in Outlook Express 6 for IMAP accounts. Granted, when moving a message you can only dump to "Local Folders", but at least you have the option. (For those that don’t know, Windows Live Mail strongly suggests it’s a modern "flavor" of the older OE 6 client.)

I’m sticking with Mozilla Thunderbird because I absolutely require the ability to set rules and filters.

Think of it this way: Imagine a Gmail with no ability to use tags. That would suck, wouldn’t it? That’s what using the Windows Live Mail client is like. Great client, great interface, crappy functionality.

This makes me mad because otherwise the Windows Live Mail client is really good - said sincerely.
