To develop an effective public folder strategy, you must first understand public folder architecture. It is important to develop a public folder policy for your organization early in the planning process. Policy decisions about the public folder hierarchy and access to public folders influence where public folders are created and how much disk storage, CPU power, and memory you need to achieve adequate performance levels.
When you plan your public folder strategy, consider whether you want all your messages to be located in one public folder or in many public folders. This decision is important because it determines whether you need to replicate public folders to other servers.
