Hello
If you received an error message like this, it typically means you are using volume license, typically the MAK type.
You bought this from third party, is that correct?
What's the full name of your Office 2019? For example, is its Office 2019 Stanard, or Pro Plus, or LTSC?
If it is any of those names, it is not designed for home users. It is a volume license, which means it is intended for organizations, not individuals. These licenses are managed by an organization’s IT department and are tied to a contract with Microsoft. Because of how volume licensing works, activation may depend on things like installation limits or periodic validation through an organization’s KMS server. Those processes require IT support from the organization that owns the license. That is why these licenses are not meant to be sold to individuals. Home users typically do not have access to the IT infrastructure needed to manage or maintain them. Unfortunately, some third-party sellers offer these licenses at very low prices. They may seem like a good deal, but they are often resold in ways that violate the licensing terms. Most buyers are not aware of these details until problems occur.
