SUMMARY
In Microsoft Exchange Server 2003 and in Microsoft Exchange 2000 Server, a public folder tree can be either a Messaging Application Programming Interface (MAPI) clients folder tree or a general purpose folder tree.

Although there can be only one MAPI clients folder tree per organization, there can be several general purpose folder trees per server.

When viewed through the LDP utility (a Lightweight Directory Access Protocol [LDAP] client utility that is included with Windows 2000), the value for the msExchPFTreeType attribute is 1 for a MAPI clients folder tree and 0 for a general purpose folder tree.



MORE INFORMATION
The public folder tree is also referred to as a Top Level Hierarchy (TLH). The MAPI clients folder tree is referred to as a MAPI TLH. A general purpose folder tree is referred to as an application TLH.
