"CalendarAgent wants to use your confidential information stored in "Exchange Access Group" in your keychain."
Since installing Mountain Lion I keep getting the message "CalendarAgent wants to use your confidential information stored in "Exchange Access Group" in your keychain." Even when I accept allow, it keeps prompting, let alone when I deny it. It is super-irritating. What happened?
I have cleaned my machine, and did disk repair from my Disk Utility. The problem still persists.
Advice, pls.
MacBook Pro, Mac OS X (10.6.8)
