Calendars, Contacts and Calendars
Pubic Folders incorporate calendars, contacts and other information. Concepts like corporate events calendars and department calendars, for instance. are excellent uses for Public Folders, particularly for situations in which all employees within the company should have access to this information.
Calendars inside Public Folders display with calendar view in Outlook precisely as they would in a calendar folder of the mailbox. Users experience the same, and it has immense value if for the reason that there isn't any budget or time (of any size) should be spent to educate users about the function.
Contact folders are another excellent use for Public Folders. A departmental folder for contacts is not the only use for such one, particularly for situations where the communications contained in the folder are project or specific. Exchange administrators wouldn't need many contact objects added to the Exchange Address Book (GAL) for these scenarios. However, keeping information on a customer's contact or specific contact information in an account can prove beneficial.
Another benefit of Public Folders is the storage of templates for companies. For instance, an organization might create the following Excel and Word templates that employees can use for tasks such as "leave/vacation demands", "purchase orders," etc. This could be even done on a departmental basis.
So long as the concept is appropriately managed and doesn't transform into the idea of a "file repository", it works effectively and usually better than the shared file system. Consider that the duplicate template files within a company "share" on an existing file system are likely not to be accessible to users travelling far from the company's network; however, they could access the information via Public Folders with ease.
