Why does Outlook only support one Exchange Server per profile?

You already have a Microsoft Exchange Server account set up. Outlook supports only one Exchange Server account at a time.

I've always found this to be one fot he most frustrating error messages in Outlook. I was hoping this would be addressed in Outlook 12, but apparently not.

I would love to be able to open two Exchange mailboxes (work and home) at the same time. Other things like POP3 and IMAP are often blocked, but being able to open the mailbox with RPC over HTTP(S) is a very compelling scenario.

Can anyone shed any technical reason for this limitation? Or better yet - anyone have a workaround for this? ( other than creating 2 separate profiles which can't be opened simultaneously )
