why can't i add multiple email accounts to icloud mail, just like i can on my devices?

Mail on iCloud.com is simply the web interface for your iCloud mail. You can not add accounts just like you can't add accounts to Yahoo mail, Gmail or any other email providers web interface.

This is not a full featured Mail app and was never meant to be. It simply allows access to your iCloud Mail only.

As a work around, you can always forward all your other accounts to your iCloud accont if you need to be able to access them from iCloud.com.

I can not speak for Apple but I am fairly sure this is nothing they are working on but feel free to leave your feeback here.

I think most people use a mail client application installed on their computer that fetches mail from all their acconts for them so they have no need or desire to navigate to a webpage to check their mail. I think Apple realizes this and therefore feels no need to overcomplicate Mail on iCloud.com.

Since you are a Windows user, I assume you have iCloud Contol Panel installed.

Here is a guide to setting up iCloud Mail, see the Windows section: iCloud: Set up iCloud Mail on your devices - Support - Apple

Also, there are free email clients you can try if you are having problems with Outlook.

iCloud isn't a mail application: it's an email service, and as such provides a web interface but handles only its own emails.

Just being thorough. I didn't want to assume you knew how to setup iCloud mail on your PC.

I am wondering, iCloud now has the iOS7 update and all the apps sync exactly the same way they do with my devices, even the app icons are identical. Then there is the Mail app, which doesnt allow me to "Add Accounts" from a third party like i can on my devices; making it useless for people like me with private domains. Even the Mail app icon is the same indicating that its the same as on devices, except it only allows you to use your @me and @icloud adress. Whats the deal?

I'd just add that iCloud has nothing at all to do with iOS 7. iOS 7 is an operating system for Apple's mobile devices. iCloud is a distributed computing email and storage service running on Apple's server farms scattered around the globe. iCloud does not "run on iOS" and in fact has nothing at all to do with iOS or OS X.

Apple makes clients and applications to access iCloud services from iOS, OS X and windows, but iCloud itself has nothing to do with any of these.

Okay, sorry. It's just anyone else reading that first line might be unaware of the distinction between the service, iCloud, and just what "iOS" is, since the forums get people with all possible levels of experience with Apple and computers in general.
