Many organizations maintain Outlook PST archives to preserve historical mailbox data for audits, legal requirements, or long-term record retention. When the time comes to Import PST Files to Office 365, maintaining complete mailbox integrity becomes essential. Missing emails, broken folder structures, or incomplete imports can create unnecessary challenges. The Cigati PST to Office 365 Migration Tool enables organizations to import single or multiple PST files into Office 365 while preserving emails, attachments, contacts, calendars, tasks, notes, and the original folder hierarchy. It also supports selective migration and bulk processing, helping IT teams efficiently migrate archived Outlook data without altering the existing mailbox structure or metadata.
