USE OF MAILBOX FOR STORING METADATA IN CONFLICT RESOLUTION

Metadata associated with contact unification, which may involve conflict resolution and de-duplication, is stored in a user's mailbox for optimizing future automated unification operations, sharing of information between different clients and services, and providing relational data that can be used for other applications. User interactions regarding unification such as rejection or acceptance of automated actions, usage of created unified contacts, as well as data from external applications and services may be analyzed and stored in the mailbox. Such metadata may then be used to resolve conflicts the same user or other users in future contact unification operations and shared with other applications and services through a predefined schema such that those applications and services can update their data as well.
