I am trying to set up outlook on the PC side. I am running Windows 8. Outllook works fine on the mac. I need to set it up on the PC for integration with my CRM. When I try to set up on the PC it will not connect to my exchange server. I get the following errors. "Microsoft Exchange is unavailable. Outllook must be online connected to complete this action" "Cannot start Microsoft outlook. Cannot open the Outlook Window. The set of folders cannot be opened. The File C:\Users\computer name\Appdata\local\micosoft\outlook\myemail.ost is not an oulook data file (.ost)." Any advice?
