About OFT and PST

OFT

OFT is an Outlook File Template designed for creating pre-formatted email messages with consistent styling, placeholders, and embedded resources. While useful for template management, OFT files are not designed for long-term email storage and lack the comprehensive organizational features of PST archives.

PST

PST is Microsoft Outlook's full-featured storage format that organizes emails, calendars, contacts, and attachments in a searchable, structured archive. Converting OFT to PST converts template files into properly stored, searchable email archive entries.

Common Use Cases

  • Convert used OFT templates to PST format for inclusion in a compliance email archive.
  • Transform OFT template records into PST for centralized search across all Outlook data.
  • Import OFT files into a PST archive for a complete backup of all Outlook-related content.
