Does GroupWise allow groups to be resolved? I've found some hints at this in documentation, but nothing confirmed or shown by code samples. In fact, I haven't seen anyone trying to send messages to groups.

Based on API, it seems that one should be able to add a group to the recipients object and then have the recipients object resolve the group. Example c# code would be this:

Recipients recipients = mailMessage.Recipients;
recipients.Add([arguments needed with group display name]);

Is this possible? If not, the alternative is to develop a recursive algorithm that walks through that group, any subgroups, building up the egwTo recipients, egwCC recipients, and egwBC recipients.
