Hello,
I installed Office Home & Business 2021 with offline installer on computer that is partially blocked from using Internet. What domains do I need to unblock to be able to perform the activation process?

    Hi,
    Based on your problem description, are you wondering how to connect to Microsoft's activation server?
    Since this content is not my responsibility, you can refer to this link for the URL and IP address range of Office: Office 365 URLs and IP address ranges

    In addition, a method for offline activation of a phone is provided:
    Obtain the installation ID and confirmation ID and enter the confirmation ID through the phone activation wizard, you can refer to this article for related information: Activate by telephone

    If you still have questions please reply me here.

    Best regards，

    Offline activation would be an ideal option. I did that in previous versions of Microsoft Office. This time i bought Microsoft Office Home & Business 2021 and I don't see option to activate it by telephone. If it is possible tell me how

    Different 2021 license versions are available. Some will have the phone option like LTSC and some GOV versions, others do not include phone activation.
