I hope it's not dying. I don't really like clouds. Call me anti-establishment. I like the idea that I have my e-mails on my computer and that they won't get lost and they're not on some server. I don't need a fiasco like Sidekick users had to deal with.I think your instincts are correct. If you continue to use Outlook Express be prepared for ongoing integration problems. It's a dying if not dead product. (Not to be confused with Outlook.) And it's increasingly difficult to find products that interface with it well.
Well, I've bee using gmail for five years. My account has about 30,000 saved emails in it. Can find any email I've ever sent or received over that time in seconds. And I'm currently using 20% of my allotted free space on the google servers. Never lost an email. And I can count on one hand the number of times the servers have been down when I needed gmail over 5 years.
I also have Outlook where all of the same email collects. I have multiple archives of old emails because even with improvements over the years, I can only keep about 18 months of emails in a single archive. Search is a pita and inaccurate. And Outlook crashes about once a month requiring an extensive rebuilding of its indexes that takes about half an hour.
But all of that has nothing to do with my original point. If you are using Outlook EXPRESS, you are using a product that Microsoft itself has abandoned. If you don't trust the "cloud," I suggest you find another pc client for your email. If Outlook serves your needs, go for it. Otherwise, you can move to an email client like Thunderbird (from the Mozilla folks) and at least you'll have an email client with a future.
