An electronic messaging client caches copies of a subset of electronic messages available in a remote store in a local store of a user device. When the user device is in an online state, the client provides for the blended presentation of electronic messages such that a user can concurrently view information about the electronic messages that have been cached in the local store as well as information about electronic messages that are stored only in the remote store. The client also presents a blended state associated with a container of electronic messages to a user of a user device and enables a user to execute a search of cached electronic messages stored in a local store as well as of electronic messages stored in the remote store.
