Question:

“What is the maximum size limit for PST files that can be managed effectively by PST Manager?”

Answer:

–

Outlook 2003 and 2007: The recommended maximum size for a Unicode PST file is 20GB

.

–

Outlook 2010, 2013, 2016, 2019, and Office 365: The default maximum size for a Unicode PST file is 50GB

, but this can be increased.

Technical Limit:

The technical limit for a Unicode PST file is approximately

4PB (4096TB)

, which is far beyond what any user would typically require.

Registry Adjustments:

Users can adjust the maximum size limit for PST files via the Windows Registry. This involves setting two values: `MaxLargeFileSize` and `WarnLargeFileSize`. The former determines the maximum size that the PST file can grow to, while the latter sets the threshold at which users receive a warning that the file is nearing its maximum size.

Practical Considerations:

Despite these large size limits, it’s important to note that very large PST files can become prone to corruption and may lead to performance issues. Therefore, it’s recommended to keep PST files well below the maximum limit to ensure smooth operation and to facilitate easier management and backup.

PST Manager’s Role:

PST Manager can effectively handle PST files up to the maximum size allowed by Outlook. However, for optimal performance and to avoid potential data loss, it’s advisable to maintain PST files at a manageable size, well within the recommended limits.

In conclusion, while PST Manager and Outlook can technically support very large PST files, it’s best practice to manage PST files that are significantly smaller than the maximum allowed size to ensure data integrity and maintain efficient access to your emails.
