I am a new student and the school uses IMAP. I have set it up with outlook and everything works well on the PC. However, i set up the email on my BB Curve and it only receives emails either extremely delayed (like 10 hours) or whenever i send receive outlook, my blackberry almost immediately gets the emails.
I'm having the same problem. Although I exchanged my device last night and tried sending service books, pulled the battery, provisioned my connections.
