On the owner's account, all the messages in his inbox appear to have disappeared. Normally, I would suspect someone deleted the messages, but the folder's messageCount suggests otherwise.
EDIT: I'm beginning to suspect that no messages are missing, but that the message count is inaccurate. Looking at the mailbox at different points in the last few days, the messageCount is always 77 above the actual number of messages.
Is it possible for a user to delete messages without changing the folder's message count? Is there a log I can check to determine exactly what happened to the messages. They are not in Trash, or any other folder. I know I can recover the messages, but I need to know how this happened and how to prevent it in the future.
