As you are well aware that the newer versions of Outlook email application i.e. Outlook 2007 and Outlook 2003 give a larger (20GB as against 2GB in older version ANSI format) file storage size limitation with a different PST file format (i.e. Unicode) for the Outlook personal folders. These Unicode PST files have much more storage space making them store a larger number of mail messages and other mailbox items as compared to the earlier ANSI (American National Standards Institute) file format for PST files used in MS Outlook 2002 version and earlier versions.

Outlook 2003 IMAP PST Size Issue: For some people, the information we are now giving, would seem to be very new and unfamiliar, as most of you believe that in Outlook newer versions, only Unicode format is used and not ANSI. On the contrary of this known belief, not every account in Outlook 2003 makes user of the standard Unicode format for PST. The difference comes in the IMAP4 accounts i.e. the Internet Message Access Protocol Version 4rev1 accounts and also in the HTTP accounts that still make use of ANSI format for storing PST files. Thus, on using these accounts, your application is susceptible to the same 2GB PST file size issues as they are there in the earlier Outlook versions. As a result, users of Outlook 2003 email application are always in a great need of the program management techniques so as to keep their email data of PST files remain in proper size. A great check against the augmenting Outlook IMAP PST limit is to cut PST file of large size into several smaller sections. Thus, a split PST software can help you resolve Outlook 2003 IMAP problems easily by splitting Outlook 2003 IMAP PST.

For Further Understanding: Let’s suppose you had been using Outlook 2003 with IMAP account settings. Unknowingly and without realizing the aftereffects of 2GB PST files, you kept receiving enormous amounts of mails and out of ignorance, you never even bothered to remove the obsolete ones, or to compact PST or to archive the old emails. As the resultant effect, your PST file grew up to a very large size. Now, what you start experiencing after that was a slow paced Outlook, constant delays in receiving/sending of mails etc. On delving into the reason for this problem, you find this is actually Outlook 2003 IMAP PST size issue.

Important to Note: A huge sized PST file is susceptible to damage and corruption. Size of ANSI PST file used in the IMAP or HTTP account of MS Outlook 2003 version is limited to only 2 GB as in older Outlook versions and beyond this limit, PST can corrupt.

Some Methods You Can Try to Outlook 2003 IMAP PST Size Issue:
