Outlook Conversion Guides: Step-by-Step Tutorials

Find your OST file location. By default, it's stored in: Look for files with the .ost extension. Note the file size as larger files take longer to convert.

Select a reliable OST to PST converter such as: • SysTools OST Recovery
• Stellar Converter for OST
• Total Outlook Converter

Download the software from the official website, install it on your computer, and launch the application. Ensure you have sufficient disk space for both the original OST and the new PST file.

Browse and select your OST file. Configure conversion options such as: • Date range filtering
• Specific folder selection
• File size splitting options

Choose the output location for your PST file and start the conversion. Monitor the progress and don't interrupt the process to avoid data corruption.

Once conversion is complete, import the new PST file into Outlook: File → Open & Export → Import/Export → Import from another program or file → Outlook Data File (.pst)

Ensure Outlook is completely closed on your old computer to prevent file corruption during the transfer process.

Find your PST files in the default location: Or use File → Account Settings → Data Files to see all PST locations.

Copy all PST files to an external drive, cloud storage, or network location. Ensure the copy process completes successfully and verify file sizes match.

Copy the PST files to your new computer, preferably to the same default location or a easily accessible folder.

Launch Outlook on the new computer and import the PST files: File → Open & Export → Open Outlook Data File → Select your PST file

Open the email in Outlook → File → Print → Select "Microsoft Print to PDF" → Click Print → Choose save location

For bulk conversion and advanced features, use specialized tools like: • Total Outlook Converter
• SysTools PST to PDF Converter
• Stellar Converter for PST

When using conversion tools, configure options such as: • Include attachments as separate files
• Maintain folder structure
• Add headers and footers
• Set password protection

Start the conversion process and verify the generated PDF files maintain all necessary information including timestamps, sender details, and formatting.

Export MBOX files from your current email client: • Thunderbird: Tools → Export → Backup→ Profile
• Apple Mail: Mailbox → Export Mailbox
• Gmail: Google Takeout service

Outlook doesn't natively support MBOX import, so you'll need: • MBOX to PST converter software
• Third-party import tools
• Intermediate conversion through EML files

Use a reliable converter to transform MBOX files into PST format: • Load your MBOX files
• Select conversion options
• Choose output location
• Start conversion process

Import the converted PST file into Outlook using the standard import wizard: File → Open & Export → Import/Export → Import from another program or file

Check that all emails, folder structures, and attachments have been properly imported. Verify email count matches the original MBOX data.

Navigate to File → Open & Export → Import/Export to launch the Import and Export Wizard.

Choose "Export to a file" from the wizard options and click Next. Then select "Comma Separated Values" as the file type.

Select the Contacts folder (or specific contact folder) you want to export. You can choose from your main contacts or any subfolder.

Browse to choose where to save your CSV file. Give it a descriptive name like "Outlook_Contacts_2024.csv".

Click Finish to start the export process. The CSV file will be created with all your contact information, ready for use in Excel, Google Sheets, or database applications.

Before attempting any repair, create a backup copy of the corrupted PST file. This ensures you can retry if the first repair attempt fails.

Use Microsoft's free repair tool located at: Browse to your PST file copy and run the scan.

If ScanPST finds errors, allow it to create a backup and repair the file. If ScanPST cannot repair the file or fails to run, proceed to professional tools.

For severely corrupted files, use specialized recovery software: • Stellar Repair for Outlook
• SysTools Outlook Recovery
• Kernel for Outlook PST Repair

Once repair is complete, import the recovered PST file into Outlook. Verify that your emails, contacts, and calendar items have been successfully recovered.

To prevent future PST corruption: • Keep PST files under 50GB
• Regular backup schedule
• Proper Outlook shutdown
• Use reliable storage devices

Collect all MSG files you want to convert. These are typically individual emails saved from Outlook by dragging them to a folder or using "Save As".

Select from these conversion options: • Drag-and-drop to email clients that support EML
• Use dedicated MSG to EML converter tools
• Online conversion services (for non-sensitive data only)

Download a reliable MSG to EML converter, load your MSG files, select output location, and start conversion. Professional tools handle batch conversion efficiently.

Open MSG files in Outlook, then forward or save them in EML-compatible email clients like Thunderbird. This method preserves all formatting and attachments.

Open the converted EML files in any email client to verify that: • All text content is preserved
• Attachments are intact
• Headers and metadata are maintained
• Formatting appears correctly
