SUMMARY
In Microsoft Outlook 98, a feature, "Allow upgrade to large tables," is available for Personal Folder (.pst) files. This feature increases the limit on the number of folders per file and the number of messages per folder in a .pst file. The limit has been increased from approximately 16,000 folders per file and messages per folder to approximately 64,000.
