Migrating an cPanel Email POP/IMAP onto Office 365

When migrating an account from a cPanel POP or IMAP setup onto Office 365 you want to carry with you the emails, folders, contacts, and calendar events that you've already setup into the new Office 365 account. To do this Microsoft Office desktop application offers an export and import feature so you can create a portable PST file that you will import into Office 365.

To start, ensure you have access to both your existing and the new Office 365 email address. In this example we are migrating the same email, but these steps would work to import data from one account into another.

  • Create your PST Export

    • Open Outlook Desktop (WINDOWS)
    • Select File, then Open & Export, then Import/Export
    • Select "Export to a file" from the dialog and press Next
    • Select "Outlook Data File (.pst)" from the dialog and press Next
    • Select thge folder (account) you wish to export
    • Check the "Include Subfolders" option and press Next
    • Enter a file path/name for the export (eg d:/backup.pst)
    • Select "Replace duplicates with items exported"
    • Press Finish

  • Remove the Account from Outlook

    • If you have ONE account, then follow the steps "Remove your Outlook Profile"
