Cigati PST Viewer Tool

The Cigati PST Viewer is designed to open, preview, and export Outlook PST/OST files, including recovered or corrupted mailbox items, into multiple formats. It preserves folder structure, attachments, and email details throughout the process. Built for both individual users and IT professionals, it lets you inspect mailbox contents before exporting and apply detailed filters to control exactly what gets saved.

Step-1

Launch the Software

Open Cigati PST Viewer. The Dashboard shows the toolbar (Add Outlook File, Save Outlook File, Migrate to Office 365, Remove File, View Logs), an empty Mail Folders panel with a Drag and Drop zone, an empty Email List with search and columns for From/Subject/To/Date, and an Email Details pane below.

step

Step-2

List Outlook Profiles

A prompt appears asking if the app should identify and list all available Outlook profiles automatically. Choose Load Outlook Files to scan automatically, or Choose Manually to select files yourself.

step

Step-3

Browse PST/OST Files

In the Select Outlook Data File window, use the Choose Manually tab. Click Browse to pick a single file, or use Add Folder/Find to locate PST/OST files in bulk. Review the file list, then click Load.

step

Step-4

Review Loaded Files

Once loaded, the Mail Folders panel populates with a tree of all detected PST/OST files and subfolders, each showing item counts and checkboxes. The status bar confirms the total number of loaded files (e.g., "Loaded Files: 16").

step

Step-5

Preview Mailbox Data

Select any folder in the tree to view its emails in the Email List (From, Subject, To, Date, with an attachment icon where relevant).

step

Step-6

Preview Individual Items

Click any email to view its details in the Email Details pane, using the tabs Body, Attachments, Task, Notes, Header, MIME, or Raw HTML.

step

Step-7

Choose Destination

Click Save Outlook File to open Filters & Options. Under Save Format, select the output type: Outlook Data file (.PST), Email Message (.EML), Outlook Message (.MSG), PDF Document (.PDF), MBOX Mail Archive (.MBOX), or CSV Spreadsheet (.CSV).

step

Step-8

Configure General Settings

Use the available options to customize the export:

  • Duplicate Handling: Remove duplicate items before saving (skips duplicate emails/contacts).
  • Attachment Handling: Keep attachments, extract them separately, or exclude them.
  • Custom Folder: Use a custom folder name for the export, or default to a day/date/time folder.
  • Date Filter: Restrict the export to a specific date range (Start Date/End Date).
  • Split PST File: Enable splitting and set a size limit (MB or GB) and store name for large PST files.
step

Step-9

Configure Advanced Controls

Fine-tune the export with additional filters:

  • Duplicate Email Filter: Save duplicates in a separate folder, optionally preserving the original folder hierarchy, and choose which fields (To, From, Subject, CC, BCC, Body) define a duplicate match.
  • Text Filter: Filter emails by specific To, From, or Subject values using the provided dropdowns and text fields.
step

Additional Features

  • Skip/Resume Detection: Enable this to safely resume interrupted exports — already-completed PST files in the output folder are skipped, and only incomplete or new files continue exporting.
  • Not Complete Files List: Displays any unfinished PST files along with their target and output paths.
step

Step-10

Select Destination & Configure Export Settings

Enter or browse to your Destination Path, review all configured filters, and click Save to begin exporting the emails according to your selected format and settings.
