SUMMARY
In Microsoft Outlook, 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 approximately 64,000 messages per folder.



MORE INFORMATION
Selecting this personal folders option causes the headers of the .pst file to be permanently updated.

NOTE: Earlier versions of Microsoft Exchange and Outlook may be able to access a .pst file that has been updated to allow the large table format. However, this is not supported and may cause instability and corruption in the .pst file.
