Hi Everybody....this is my first post. With the purchase of another company, our company consists of two domains. We have the trust setup between them. We had a consultant setup GAL syncronization between our two Exhange Systems (2003 and 2000). Company A's GAL now shows company B's email users as contacts and vice versa. Is it possible at all to have a Company A user to share their calendar to a Company B user, which is listed as only a contact in their GAL? Thanks, Arnie

One option would be to synchronise the free/busy information between the two Exchange orgs. You will need the InterOrg Replication Tool for this. http://www.microsoft.com/downloads/details.aspx?FamilyId=E7A951D7-1559-4F8F-B400-488B0C52430E&displaylang=en Tony www.activedir.org

The InterOrg sync works fine (we have it in place) but still doesn't solve the "share calendar" issue. Do you have other suggestions concerning this?
