Click PST/OST Migration to begin.

Step 2: Load Your PST/OST Files

On the Select Files screen, you have two options:

• Select PST/OST: Click this to browse and load one or more individual PST/OST files from your system.
• Select Folder: Click this to load an entire folder containing multiple PST/OST files at once, recommended for bulk migrations.

Once your files are loaded, click Next to proceed to the Preview panel.

Step 3: Preview the loaded PST/OST files

The Preview panel displays the complete folder tree of your loaded PST/OST file, including Inbox, Outbox, Sent Items, Drafts, Deleted Items, Contacts, Calendar, Tasks, and all custom folders.

• Click any folder in the left panel to load its emails in the center panel.
• Use the search tab or dropdown to filter emails by Subject, From, or To.
• Click any email to preview its full content in the right panel.
• Once you have reviewed your data and confirmed it is loading correctly, click Next to move to the destination settings.

Step 4: Choose Your Destination

The Filters screen offers two destination tabs:

  • Modern Authentication: Secure OAuth-based login via Microsoft sign-in
  • Client Secret: Application-level access using a registered Azure app and secret key
• Single Login: Use this for individual personal or business mailbox access. Single Login authenticates one mailbox at a time and is suitable for personal migrations or single-user business account transfers

Step 7: Add Connection and Authenticate

• Custom Folder Name: Define a custom name for the migrated folder in the destination
• Duplicate Handling: Automatically removes duplicate items based on your selected parameters

Step 10: Start Migration

Click Start Migration. The software authenticates with Office 365, applies all configured filters, and migrates all selected data directly into the destination mailbox without any manual import steps.
