  2. Expand Configuration Properties, and click Debugging.

Using the application

  • In message list view, tap & hold a message item. You will see the new menu options in the context menu that appears. These include Add Sender to Contacts, Mark All as Read, and Delete All.


InboxMenuExtensibility populates the appropriate registry settings via DllRegisterServer, which is called when the solution is deployed to a device.

The menu option Add Sender to Contacts creates a new Contact item, populates its FileAs property with the e-mail message's Display Name, and populates the Email property with the e-mail message's Email Address. If there is no Display Name, it only populates the Email property. This menu option does not parse the display name or e-mail address, and it is enabled for incoming mail folders only. It does not appear in Outbox, Sent Items, or Drafts. It appears on single message items only.

It is assumed that you have both "read" and "unread" e-mail in your Inbox.
