- Migrating Outlook data to a new system

Method 1: Use Microsoft Outlook’s Export Feature
If your Outlook account is still active, follow these steps:

- Choose the folders you want to export (e.g., Inbox) and click Next.
- Browse to the location where you want to save the PST file and click Finish.
Note: This method requires an active Outlook profile connected to the OST file.
Method 2: Use a Professional OST to PST Converter Tool
If you can’t access Outlook or the OST file is orphaned or corrupted, a third-party tool is your best bet. These tools can:

Look for tools with free trial versions so you can test before purchasing.
Method 3: Use Outlook Archive Option
Archiving can help in partial conversion:
