Hi All, I am developing add-in using C# 2.0 and VSTO for MS Outlook 2003 which is configured for Exchange Server 2003 SP1. Is there is any way to access security group(s) of current user from the add-in code? I thought of executing Active Directory query on my exchange server in add-in but got stuck by unavailability of Exchange Server LDAP address in MAPI/CDO object model. Also, I am not pretty sure if I'll be impersonated as current user while executing LDAP query or I need to prompt user for password for executing the same? I'll greatly appreciate if you could please answer these queries. Thanks.
