Dear yzx0023,Your belog is damn good!!! Sometimes is better than reading MSDN. This is KAOYI LIN, I am a MMI developer in Taiwan. Recently, I got a "impossible mission" from my boss. He told me to create an app which is exactly like I-phone Visual Voicemail. Please analyze my thought a little bit. Let's begine, first, I use "EMAIL2 Configuration Service Provider" to create a new account in Messaging Inbox, I used sample code "TransportDemo" to be the transport for the account. But I really want to remove some folders from message store since the "Visual Voicemail" may not need "Draft". So, I also work on sample code "TV_INBOX" which is about creating custom form. However, I got lots of question and no one can help me... Please post some good articles about how to create a transprot, how to customize the message form, and how to obtain "Visaul Voicemail"Thank you very much!!!!MY EMAIL is : kaoyi.lin@gmail.comalternative one is kaoyiking@hotmail.comPLEASE~~~~~YOU MAYBE THE ONLY PERSON CAN HELP IN THIS WORLD!!!!Thank you
