Stellar Repair for Outlook – Software Review

MS Outlook, when configured with POP3 email account, stores all the mailbox data in a PST file on your system. This PST file, sometimes, gets corrupt due to various reasons such as system crash, virus infection, large PST file size, etc. If your PST file gets corrupted or damaged, it can make Outlook unstable, thus hampering your workflow.
