Any messages will be in your inbox. This site software calls them conversations but most people here call them PM (personal message) which dates from the previous software. I don't much use it and rarely get one. I guess the spam engine scans the inboxes- that is the only reason I can think for a number(unread) to set to zero. The mailbox appears to be configured as a private thread. Tbe first words of your post established you were from US. Canon don't brand their DSLRs as "Rebel" in Europe! You can also edit your pofile if you want.
