set two exchange account from 2 domain

the owner of our company owns 2 different company, in which host their own exchange server in 2 domain with no vpn or link to each other.

Currently he is access other company via outlook anywhere using outlook 2007, when he is at our office. now he want to access our company's public folder. Is there a way that allow him to access both company's exchange server without setting 2 profiles. So he can access both exchange server's mailbox at the same time.

Right 2 company's exchange server is in complete separate network, domain and with no trust relationship at all.

No, it is not possible to have two mailboxes in two separate Exchange organizations in the same Outlook profile.

You cannot use two Exchange accounts in one profile.  Separate profiles is the only way to go.

One option is perhaps using OWA if it's avaialble.  That would prevent him from having to switch back and forth all the time.
