Abstract: Media, system, and method for providing encryption key management to a channel within a group-based communication system. The contents of the channel is encrypted according to the encryption key management policy of the organization to which the author of the content belongs and is stored in a data store. Responsive to a revocation request from a first organization, the encryption keys associated with any content in the channel submitted by the authors of said first organization may be revoked from a second organization, such that users of the second organization no longer have access to the content.

Abstract: Managing organization disconnections from a shared resource of a communication platform is described. In a sharing approval repository of a communication platform, a shared resource can be associated with a host organization identifier and a non-host organization identifier. In an example, in response to receiving, from a user computing device associated with the host organization identifier or the non-host organization identifier, a resource disconnection request comprising a disconnecting organization identifier and a resource identifier associated with the shared resource, the sharing approval repository can be updated to add a disconnection indication for the resource identifier in association with the disconnecting organization identifier.

Abstract: Techniques for updating a user interface associated with a communication platform are described herein. The communication platform can enable communications between two or more organizations, such as via a shared resource. The shared resource can include a communication channel, workspace, direct messaging instance, board, or other resource associated with messaging communications. In some examples, the communication platform can receive a request to view a shared resource and can identify two or more organizations associated with the shared resource. Based on the identified two or more organizations, the communication platform can cause a user interface to be presented on a computing device associated with the request. The user interface can include indicators and/or data associated with the two or more organizations, such as to provide an indication that messages transmitted via the shared resource will be shared with members of different organizations.

Abstract: Embodiments described herein include apparatuses, computer program products, and methods for data management in a group-based communication system. Specifically, some embodiments address data management for group-based communication channel(s) accessible to any number of entities based on various data retention policies. In this regard, embodiments enable maintenance of data associated with multiple organizations accessing a group-based communication channel based on a single, shared data retention policy, or different data retention policies, for example based on authorship of the group-based communication message. In embodiments, a data retention policy may be assigned directly to an entity, or assigned to a higher-level or lower-level entity and function as a default data a retention policy for other entities associated therewith.

Abstract: Techniques for performing dynamic profile reconciliation in a communication system. A server computing system may identify two or more user profiles corresponding to a same user that is associated with the communication system. The server computing system may integrate historical data associated with the two or more user profiles into a single user profile (e.g., a destination user profile). The historical data may include messages sent and/or received via the two or more user profiles, files associated with the messages, metadata corresponding to each message, and the like. Responsive to combining the two or more user profiles into the single user profile, the server computing system may delete at least one of the two or more user profiles, storing the combined data in association with the single user profile.

Abstract: Techniques for dynamically converting a communication channel associated with a communication channel from a communication channel associated with a single organization to a shared communication channel associated with two or more organizations. The communication channel may have associated therewith member profiles associated with a first organization and one or more guest profiles associated with one or more other organizations that are different from the first organization. A server computing system may convert the communication channel to a shared communication channel based on a determination of eligibility for conversion. The server computing system may generate one or more user interfaces associated with the member profiles and the one or more guest profiles, enabling members and guests to communicate via the shared communication channel.

Abstract: Hosted communication channels associated with a communication platform are described. In an example, a user can utilize communication services available via a communication platform. In some examples, a first organization can invite a second organization to join a communication channel. The two organizations can be different such that they are associated with different organization identifiers and are associated with different permissions. In some examples, content associated with each organization can be private, such that other organizations cannot access content that is owned or otherwise managed by each organization. However, content posted to shared communication channels can be accessed, viewed, interacted with, or the like by any member of the shared communication channels. To address privacy and/or security concerns, some organizations or users of the communication platform may desire to control how end users that join a shared communication channel interact with the shared communication channel.
