Are you sure you have selected the - ROAM commanline option??
-ROAM This option tells Pegasus Mail that it should ignore the configured drive letter when locating user mailboxes and mail files, and should instead use the drive letter of the drive from which WINPM-32.EXE was run. If Pegasus Mail and your mailbox directories are located on the same physical drive, you should always use this option. -ROAM greatly simplifies running the program on Peer-to-Peer and non-NetWare networks, because it allows the same copy of the program tobe run no matter what drive letter mappings exist on the particular workstation where it runs. This switch also allows you to install a complete, working copy of Pegasus Mail, complete with mailboxes, onto a memory stick, and to use that memory stick in any computer where it is subsequently plugged. You must not use this switch if Pegasus Mail and your mailbox directories cannot be accessed using the same drive letter. This switch is ignored and has no effect in either Novell NetWare operating mode.
