Can ISYS:email.search index my Personal Folders?
ISYS:email.search will index emails contained in Personal Folders, providing they are open in Outlook. ISYS:email.search does not have the ability to open a PST file on your system and as such needs Outlook to have opened the file. To open these files, select File > Open from the menu. Click on the Personal Folder File option and navigate to your PST file.
