Abstract: Architecture for retention policy tagging of data items such as messages for expiring data items without data reorganization. Retention policy tags can be applied to items, conversations, folders, and/or distribution lists, for example. Retention policy tags provide a way to manage (e.g., expire) data items such as email, for example, and reduce the corporate burden for compliance in documents of all types. Tags can be applied to data items individually and in-place, and do not impose changes to the natural workflow of the user. The use of expiry policy tags provides a solution by removing the pain point around physically moving messages to an unfamiliar folder hierarchy.

Abstract: An autodiscovery service for clients in an electronic messaging system is disclosed. Client devices in the system request messaging system configuration settings from an autodiscover server. Clients may derive the address of the autodiscover server from user input, such as an email address, or the address may be obtained by other means. The autodiscover server responds to the request with settings for that client. The settings requested may include addresses of electronic mail servers and other servers that provide client services. The autodiscover server may determine the settings for the client based on various criteria, including client location and user mailbox location. Third party servers may participate in the autodiscovery service, and addresses of third party servers may be included in the settings provided to the client devices.

Abstract: Methods, systems, and computer-readable mediums configure electronic messaging applications to communicate with a server storing messages to and/or from an electronic messaging account of a user. A method involves receiving an electronic message address and a password of the user as inputs, deriving server connection settings based on the electronic message address, and applying the server connection settings to the electronic messaging account. Another method involves receiving an electronic message address of the user and discovering the server connection settings for the electronic messaging account on a server having a designated protocol name as a server prefix name to assist in locating the server and having the server connection settings. The method also involves retrieving the server connection settings from a file provided by the server in response to locating the server having the designated name and applying the server connection settings to the electronic messaging account.
