Hi all, I am writing a backup and restore application application for Exchange server 2000 to work at Mail levels. Can somebody tell me what are all the things that are present there on the Exchange server 2000 other than Mails. And how and where they are stored ??? I guess appointments, which i can create in OUTLOOK are also stored as Messages only but with some different Message properties and Different message classes like IPM.Note etc.. Correct if am wrong ??? So using MAPI can anyone tell me how to backup and restore all the COMPONENTS that constitute exchange database . So far I have been able to backup / restore IPM messages. But i don't know how to proceed for other "DATA Items" coz IPM was default .. If my understanding is correct , is there a way to specify MAPI APIs to retrieve messages belonging to all the classes ?? Any help in this will be most appreciated.. Thanks in advance.. Jay
