I have a problem with Outlook 2010 and OST files.
First my exhange hosting company deleted my exchange account by accident. They've created it on another server, but can't get the data back.
Now I did make a copy of the \users\name\appdata\local\outlook directory. So I have the original OST files.
I decided to switch hosts to Office 365. During this, I stupidly deleted my account from within outlook and recreated it to point to Office 365. And only then did I learn that you can't import from OST files.
Edited to clarify:
I have a complete backup of the pc. Which folders would I need to restore to ensure that I can get exhange back it's previous state? I'm prepared to to a complete restore if necessary, but would prefer to localise the changes.
