What Contact sharing options are there in Google Apps?

I setup Google Contacts in Google Apps for several people. I'm wondering if there is any way to share (at least some of) the contacts between everyone in this domain. Similar to how you can share your Calendar with people in the same domain.

I know about enabling Contact sharing, but it seems like that will only share the contact information of people in the same domain. I'm looking for an easy way to share the hundred or so non-domain contacts.

Now that it has ActiveSync/Exchange support, are there any workarounds available at least?

• There is really no good contact sharing. There is a global contacts list for your domain but it cannot be managed through the Google interfaces. It can be used via a custom program using the contacts API, and there are some 3rd party tools that are good. One recommendation is called sherpa tools, its in the market place for free.

  I work as a Google Apps re-seller, and this has been one of the largest pain points for customers so far. For what its worth, its also one of the most requested things to address for Google Apps suggestions. Hopefully they are working on it.

  In short, your best bet is to use a tool or program to import your existing shared contacts into the domain shared contacts list. It's worth noting that even after you do this, users should be able to search these contacts from their own contacts list, they show up in search results and a note is displayed that the result came from the global list when a contact is selected.

  Senseful : So there's no way to see all the contacts in the Global Address List?

  Brad Gardner : Unfortunately not within the Google interfaces yet. Huge missing feature IMO.

• We use the Floreysoft Shared Contacts app for Google Apps on our domain. Very flexible sharing options and integrates nicely into the Google Apps interface. Highly recommended.
