EXEC sp_addlinkedserver 'ADSI', 'Active Directory Services' ,
'ADSDSOObject', 'adsdatasource'
GO

select * from openquery (ADSI, 'Select name, adsPath FROM '' LDAP://DC=HQMAIL1, DC=com''
WHERE objectCategory = ''Person'' AND objectClass= ''user''')


Server: Msg 7321, Level 16, State 2, Line 1
An error occurred while preparing a query for execution against OLE DB provider 'ADSDSOObject'.

Do you know why I am receiving this error message?

It is most likely your LDAP query syntax. Without any knowledge of the Active Directory you are trying to talk to, I can't tell you for sure what the problem is, but you can read this Article for more information.
