How to Increase PST Size Limit from 2GB to 20 GB?

Are you using an older version of Outlook for a long period of time? It is important to note that older versions store email data in ANSI PST format while newer versions stores email data in Unicode format. In newer Outlook versions (2003 and 2007), the PST file size limit is 20 GB which is in the Unicode PST format; whereas it is 2 GB in older Outlook versions (2000 and 2002) where it is in ANSI PST format, which you may be using. Now to increase Outlook mailbox size from 2 GB t0 20 GB i.e. from ANSI to UNICODE, you need to upgrade Outlook PST file from Outlook ANSI to Unicode.

To upgrade PST, you need to perform PST file conversion process from ANSI to Unicode and you can easily convert PST file from 2000/2002 to 2003/2007 version. There are a few methods available for this conversion of PST file, which will increase Outlook mailbox size from 2 GB to 20 GB.
