Microsoft Outlook 2007 and Microsoft Outlook 2003 impose a larger file size limit and a different file format (Unicode) for its personal folders. Also termed as PSTs, these files can now store more messages as compared to earlier American National Standards Institute (ANSI) format files used in Microsoft Outlook 2002 and earlier. But contrary to popular belief, not all accounts in Microsoft Outlook 2003 use the standard Unicode file format. The Internet Message Access Protocol Version 4rev1 (IMAP4) accounts and HTTP accounts in Outlook 2003 still use ANSI PST files and thus are susceptible to same file size issues as in earlier versions. Consequently, Outlook 2003 users need more management techniques to keep their PST files in size. One of the best remedy against increasing size of an Outlook 2003 PST in these accounts is to Split PST File.



For more understanding on the topic, let's suppose that you use Microsoft Outlook 2003 with an IMAP account. Without realizing the fact that PST can store only limited number of e-mails, you continue receiving large number of e-mails. As a result, the PST file grows to a considerable size value. You start observing several performance issues such as, slow Outlook, delays in receiving and sending e-mails, and more. On investigating the issue, you find the PST file size large.



Note: A large PST is prone to corruption. An ANSI PST, which is used in IMAP and HTTP accounts of Outlook 2003 is limited to 2 GB and can get corrupt beyond this limit.

Following are a few tips to isolate the specific issue:



(1) Upgrade to MS Outlook 2007 if you want to continue using an IMAP account, but with a PST of large size limit.


(2) Delete the unwanted e-mails, contacts, etc., and empty the 'Deleted Items' folder. Compact the PST file.


(3) Use a third-party utility to Split PST.
