A method and system for automatically managing changes to organizational data in a unified messaging (UM) platform are disclosed. A database snapshot is retrieved from a client human resources database. Added user information associated with a user is detected in the database snapshot, and an existing mailbox associated with the user in the UM platform is detected. Organizational data in the UM platform is automatically modified to combine the added user information and the existing mailbox in the UM platform. When the existing mailbox is detected in the UM platform for the user, it is possible for the UM platform to automatically compose and send a message to at least one user associated with the added user information including potential modifications of the organization data. The organizational data in the UM platform can then be modified in response to receiving approval of the potential modifications of the organizational data from at least one user associated with the added user information.
