Are you seeing only 1,500 emails after importing a PST file that actually contains around 3,500 messages? This is a fairly common issue when users try to import PST files into Microsoft 365 (https://www.cigatisolutions.com/blog/import-pst-to-office-365/). Incomplete imports can occur due to PST corruption, synchronization delays, mailbox size limitations, damaged folders, or interruptions during the Outlook import process.
You can try the manual approach first by checking the PST file with Outlook's Inbox Repair Tool (ScanPST), verifying mailbox quotas, and re-running the import. However, troubleshooting large PST files manually can be time-consuming and doesn't always guarantee complete results.
For a more reliable option, many users choose the Cigati PST to Office 365 Migration Tool (https://www.cigatisolutions.com/pst-to-office365-migration/). It helps Import PST Files to Office 365 accurately while preserving folder hierarchy and data integrity. The tool supports bulk migration of multiple PST files, offers selective migration filters, and features a simple, user-friendly interface. It is compatible with various Windows and Outlook versions and ensures a fast, secure, and accurate migration process.
If you need to Import PST Files to Office 365 without missing emails, an automated solution is often more efficient and easier to manage, especially for non-technical users handling large mailbox data.
