Microsoft Outlook stores all your emails, contacts, notes, and all other mailbox information in a single file on your local hard drive, which is known as Outlook PST file. These PST files have fixed size that is predefined and varies with the version of Outlook you are using. If a PST file reaches to or crosses over this predefined size limit, then chances of its corruption are quite high. Since earlier Outlook versions (i.e. Outlook 2002 and earlier) have 2GB PST size limit, thus their users many times encounter devastating situation of PST corruption. Therefore, to overcome this issue, later Outlook versions (Outlook 2003 and higher) have increased their PST size limit to 20GB.<\/p>\n
Despite the large PST size limit, have you ever thought that what will a user do, if his\/her Outlook mailbox and thus the PST file get filled with duplicate items? Many times after configuring Outlook in PDA, Smart Phones, etc, reinstalling Outlook after system format, or after setting inappropriate rules and options on Outlook, users encounter duplicate emails. The very first symptom of filled Outlook PST file or cluttered Outlook mailbox is slow performance of Outlook. And if you ignore such behavior of Outlook, then you may encounter Outlook crash or PST corruption.<\/p>\n
