I am getting an error that states something similar:<br />
<br />
<br />
&quot;C:\Users\ChristopherHughe<wbr />s\AppData\<wbr />Local\Micr<wbr />osoft\Outl<wbr />ook\Outloo<wbr />k.pst cannot be accessed.&quot;<br />
<br />
I've downloaded the process moniter, but how can I tell if it is in use by another pogram, and then correct the issue?
