I decided to go ahead this morning and set up Outlook 2013 this morning.
When I clicked on it, it came up with this message:
"Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. The file C:UsersXXXAppDatalocalMicrosoftOutlookXXX_m sn.ost cannot be opened."
I looked the file is there, and Outlook '07 works just fine. All of the other O365 programs work great, no problems.
How do I open ost file?
