Abstract: The disclosure concerns tracking a total count of unread messages where an email service manages email messages and a subset of the email messages are also stored locally on a client device. The client device may maintain a local unread count of unread messages stored on the client device, and the email service may maintain a remote unread count of unread messages stored on the email service but not on the client device. The email service may provide the remote unread count to the client device, and the client device may determine the total unread count by adding the local unread count to the remote unread count. The client device may also provide an identifier to the email service, and the email service may use the identifier to determine which of the email messages stored on the email service are not stored on the client device.

Abstract: Systems, methods, and computer-readable storage media are provided for discovering and disambiguating identity providers such that user knowledge of appropriate identity providers is minimized. Users are presented with options for selecting appropriate providers only when multiple providers have user profiles matching a user identifier. When users are presented with options for selecting appropriate providers, providers that have user profiles matching the identifier are identified utilizing identity information for the application that utilizes the identity provider for its users rather than information identifying the identity provider itself.
