we haven't tested mixed mode environments at all; when I get back in the office (monday) I'll check what attributes the wizard looks for to determine user accounts are valid.
when the wizard logs on to exchange, it determines the version. if the version is 5.5, it shouldn't allow you to use the object picker; it should only give you access to build an LDAP query. Did you try using the LDAP query builder?
Also, is your domain 2k or NT4? |
