Gmail – Is it possible to give others access to Google Contacts without Google Apps

There is no such thing yet, but in order to speed up the process you can do the following.

For example if you have 5 e-mails for one contact.

1. Add 5 new empty e-mail fields
2. Click on the first e-mail and then press Ctrl+A to select all and Ctrl+X to cut the selection
3. Click on the first empty field and Ctrl+V to paste
4. Continue with the rest
5. Don't delete the empty fields, they will be removed automatically once you hit the save button

(If you are on a mac use Cmd instead of Ctrl)

Shared contact in Google Apps will share only the contacts with emails from the same domain.

So the current implementation makes some sense only for big corporate implementations where it's hard to keep contact with people from inside the company.

From my knowledge, most of the Google Apps clients are small to medium, where you want to share external contact. Bad luck, you have to look for a third party service, like Is there a way to share/synchronize contacts between Google accounts? - free up to 3 accounts.
