On a client computer, customer relationship management software is integrated into a messaging application that includes a user interface. Customer relationship management (CRM) information is received from a server computer. An automatic determination is made as to whether the received CRM information is to be cached on the client computer. When it is determined that the CRM information is to be cached on the client computer, the CRM information is cached in a cache on the client computer. When at least some of the CRM information is cached on the client computer, the cached CRM information is displayed as a view on the client computer. The display of the CRM information is integrated into the user interface of the messaging application program.
