Can multipple users share the same mailbox?

[Guest]

In Exchange 2003 / Outlook 2007 configuration, can multiple users share the
same mailbox (as their primary mailbox) and access it simultaneously?

I created profiles for three different users and set shared mailbox as their
primary mailbox. They all have "full access" permission for this box. When
they connect to Exchange they see some strange message saying that "temporary
mailbox was created for them" and asking them whether they want to use "Old
Data" and be restricted to read only mode or use "Temporary mailbox" and lose
"latest changes". Neither one works for us.
