Office will not activate after online repair

I was advised by MS to backup my pc. When I did this I lost Outlook calendar and contacts on both original and backup drives. An Office quick repair did not work so I performed an on-line repair. I now get a message telling me to active Office, but then get a window with nothing in it. The system just sits there and does not update. There is no error message. Just a blank screen and I have to use task manager to exit. How do I fix this please?

    Hi @David Wright

    I’m sorry the Online Repair has left Office in a worse state, especially while you are also trying to recover the missing Outlook calendar and contacts. A completely blank activation window can indicate that the web component Office uses to display the sign-in page is not loading correctly.

    Please try repairing Microsoft Edge WebView2 Runtime:

    1. Close all Office applications and end any remaining Office processes in Task Manager.
    2. Open Settings > Apps > Installed apps.
    3. Find Microsoft Edge WebView2 Runtime, select the three-dot menu, and choose Modify > Repair.
    4. Restart Windows, open Word, and select File > Account > Sign in.

    If WebView2 is not listed or repairing it makes no difference, create a temporary new Windows user account and test Office activation there. If the sign-in window loads under the new Windows profile, the problem is likely limited to the original Windows profile rather than the Office licence itself.

    Please avoid deleting or recreating the Outlook profile until the calendar and contacts have been located. If they were stored locally rather than synchronized with an email account, changing the Outlook profile could make recovery more difficult.
