Final answer:
By default, Slack does not save messages indefinitely; message retention depends on the organization's subscribed plan and their chosen settings. Free plans retain only the most recent 10,000 messages, while paid plans offer customizable retention policies.
Step-by-step explanation:
The statement that Slack saves some of your organization's messages and files indefinitely is False by default, as Slack provides different message and file retention policies depending on the plan your organization subscribes to. The Free version of Slack retains the most recent 10,000 messages, and does not offer full message archives. However, paid plans such as Standard, Plus, and Enterprise Grid provide options for customizing message retention policies, and messages can be set to be retained indefinitely. Still, this is a setting that an organization must actively choose, and messages are not saved indefinitely by default.
The statement is true. Slack does save some of your organization's messages and files indefinitely. Slack acts as a communication and collaboration platform, and it automatically stores all the messages and files shared within it. This feature allows users to search for and access past conversations and documents at any time, making it convenient for referencing information.
