    Hi holly, this is Kimberly. I'm glad to assist you today.

    To find your contacts from a previous version of Office (especially Outlook) after switching to Office 365, here are several methods to locate and restore them:

    1. Check the Old Outlook Profile (If Still Accessible)

    If your previous Outlook profile still exists on your computer:

    Open Outlook.

    Go to File > Account Settings > Account Settings.

    Click on the Data Files tab.

    Look for any other Outlook Data Files (.pst) or Offline Outlook Data Files (.ost).

    If found, open them in Outlook:

    File > Open & Export > Open Outlook Data File (.pst).

    Check the Contacts section after opening each one.

    1. Search for PST or OST Files on Your Computer

    If the previous version of Outlook used a local data file:

    1. Press Windows + E to open File Explorer.
    2. Search for:

    *.pst

    or

    *.ost

    1. Note down file paths (typically in Documents\Outlook Files or AppData\Local\Microsoft\Outlook).
    2. In Outlook:

    Go to File > Open & Export > Open Outlook Data File, then open the found file.

    Navigate to Contacts in the opened file.

    1. Check Your Old Email Account (if still active)

    If your contacts were tied to a specific email account (e.g., Gmail, Yahoo, Exchange), re-add that account:

    File > Account Settings > Account Settings > New...

    Add the email account.

    Let Outlook sync.

    Look in the Contacts section for your old contacts.

    Should you have more questions, please let me know.

    Best regards,

    Kimberly
