A lot of you are Uni students, so I figure maybe somebody has come across this problem before. My school uses an exchange server for its email, but Mail only allows one exchange account. Which means for my other account, I have to use IMAP. The problem comes in the fact that the accounts have MANY public folders that I don't have access to. And Mail insists on trying to open these folders anyways when it traverses the hierarchy. Anyways, I get the error: Mail was unable to open this mailbox on the server "exchange". The server error encountered was access denied. Any ideas?
