It seems that Outlook 2010 will have support for multiple exchange mailboxes. After reading through some of the post comments, it does look like it will have support for caching on the extra accounts and that the max number of exchange accounts as of now is 3. That number may change by the time it hits the shelves.
I did have a couple of questions though.
1) Is Exchange 2007 going to support this? As of now, I don’t see how you can attach another mailbox to an existing user with a mailbox. Unless a future service pack will address this issue, I have a feeling only the next version of Exchange will support this. Please correct me if I am wrong.
2) How are Windows Mobile phones going to handle multiple mailboxes?
These questions have been asked in the comments, but they haven’t addressed them yet.
