I ran into a facinating issue last week. It turns out that the new form for Contact doesn’t have a navigation link for More Addresses, as it did in the past.
Here’s how to correct that issue:
1. Open the form editor for Contact.
2. On the Ribbon, Select Navigation from the Select group:
3. In the Navigation Explorer, click and drag the Addresses link to the location you wish it to reside within the Navigation pane.
4. Save your form.
5. Click the Publish button.
Addresses is now on the Contact’s navigation link:
An alternative is to add a sub-grid to the form to show the addresses.
