Hi Matt, I've try the link, but i think it doesn't seem like my problem. The problem is when i used system manager in e2k (Start - Program - Microsoft Exchange - System Manager), i can see there's 1 item in my account with 1 kb size. It also appear in account administrator. What is it ? Or maybe there's something i can't understand ? Could someone tell me about it ? I'm newbie in e2k.
