My OS is win 7 64 bit and I use Outlook 2007. &nbsp;I was running a mail merge to send emails and since it was taking a long time, I left the pc on while it ran for &nbsp;a long time and just went to bed while it kept on sending. &nbsp;but the next morning my pc was hijacked, see my Q at 2013-09-05 at 10:05:30ID28231543.<br />
And this morning when I tried to open Outlook 2007, I got the following error :<br />
<br />
Cannot open the folder. &nbsp;The set of folders cannot be opened. &nbsp;the file C:\users\Jothy\AppData\Loc<wbr />al\Microso<wbr />ft\Outlook<wbr />\Jegajothy<wbr />_msn10.pst<wbr /> cannot be accessed. &nbsp;<br />
You must connect to Microsoft Exchange at least once before u can use your office folder file. <br />
Hope the Gurus can please advise how to solve this problem. &nbsp;Thank u.
