Distribution list and outlook address book

[Guest RobWUK]

I have an issue where a member appearing in the security group doesn't appear

when you select this from the global catalog via the global address list.

The user also isn't available to add via modify. All other members appear to

be present and match.

 

As far as I understand it - the Outlook Address book distribution list

should match whats in AD. It is a universal security group i'm using as a

dist group in a single domain.
