Just got this error from an Outlook 2010 client:
Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost). P1: 300032 P2: 14.0.7015.1000 P3: heqz P4: 0x8004011D
Site power outage on Saturday and everything got a restart.
The fix was start the Microsoft Exchange RPC Client Access service.
