Outlook 365 calendar not importing pst file

[serena_b]

I just purchased a computer with Windows 8.1 and am converting from Office 2007 to 365. When I try to import contacts and calendar from pst file, nothing happens. I have tried using the import/export and with the "Open Outlook data file." With the first method, If I try it again, I receive the message that the pst file is still in use. If I use the second, I receive the message that there is nothing to show. I was able to import emails, but not with the sub-folders. How do I successfully import the information?

Update: I saw that, like the emails, the calendar information was in a separate calendar. How do I combine the calendars ? (The email folders also)

Thank you. Now I have a message that the path specified for F:\backup email.pst is not valid. How do I get rid of that?

I was able to import a pst file. However, there was one that turned out to be empty and Outlook gives me an error message about not finding the file. How do i just get rid of the error message?
