I want safe migration from Outlook 2010 to Outlook 2016 on newly bought Windows 10 PC. A month ago, my daughter did the same task, but he got damage in their Outlook database (.pst) file. However, she is now able to access lost Outlook mailbox access again through the assistance of third party software i.e. Stellar Phoenix Outlook PST Repair. But, I do not want any risk or mess with my personal and business emails.
