It’s accepted by Microsoft as legitimate (due to activation) but the path that the product key reaches you might not be entirely ‘kosher’. A cheap price and you get the software activated, albeit by some less common method. Let’s assume we’re talking about a deal like what we’ve described above. There’s no clear answer to that question because the sourcing isn’t known. That simple web page lets you type in the product key or Installation ID and, hopefully, get back an activation code you can put into Office. Use a smartphone because Microsoft will offer to send a text link to a special web page. Now it’s easier calling for phone activation. You had to type into your phone a 63 digit long Installation ID then write down a long Confirmation ID. This has been available since the start of Office software activation but is now much easier. You call a special Microsoft number to get an activation code. Just one example of the extra steps that might be needed for Office software activation.Ī common requirement is telephone activation.
