One of the most important things to consider is whether or not a repair tool is going to work with ANSI and Unicode PST files because Outlook uses both file formats over different versions.
A damaged Outlook PST file can contain years of important e-mail messages, attachments, contacts, calendar entries and other mailbox information. The first thing that comes to mind when Outlook returns errors or will not open the file is to immediately repair it.
A single Outlook PST file can hold years of email, contacts, calendars, tasks, notes and other mailbox data. When the file is corrupted the users may see that Outlook cannot open the file, folders are missing, mails are missing or individual items do not appear properly.
