Access multiple exchange servers simultaneously??

[Bob Fronk \(BTR Technologies, Inc\)]

I am looking for a way to access more than one exchange server at the same time.  I have inboxes in many different organizations and many different domains.   None of these servers is connected and none of the businesses are related.  I provide IT support for these companies, and to make it easier for the users to contact me, I have established inboxes in each organization.   I know that Outlook will only allow me to access one exchange server at a time, and I have established multiple profiles and switch between them.  However, I would really like to have a single inbox and be able to access all of the GALs and folders, etc from a single interface.   Currently, I am using one of the exchange server inboxes and have the other addresses as POP3 accounts, but this does not let me access the GALs of the other servers.   Is there a way to run multiple instances of Outlook?  Or does anyone know of an add in or other product that allows you to view multiple inboxes from one interface?   Any input is appreciated.   Thanks,   Bob   PS: all servers are 5.5 sp4 and I use Outlook 2002     List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
