Configuring Public Folder Limits
Public Folders are designed for easy shared access and to facilitate collection and organization of information that may pertain to an organization or the entire workgroup. The Exchange stores the public folders in public folder databases. These can be created only if a public folder database exists. There are two kinds of public folder trees as described below -
- Default Public Folders (IPM_Subtree): Folders that exist in this tree are more commonly accessed using applications like Outlook.
- System Public Folders (Non_IPM_Subtree): Folders that are placed under these folders are accessed by the users indirectly.
Limits like the maximum size and age can be configured on items that are posted to public folders using Public folder limits.
The maximum size of the item, retention of deleted items, age limit of items can be configured on the Limit's tab.
