The description for an Office 2019 Professional Plus key is consistent with the terms for a legitimate "retail" or "bind" license, meaning it can be linked to your Microsoft account and is transferable to a new PC, provided you uninstall it from the previous one. However, the extremely low price points at which these are typically offered online often indicate they are gray-market or volume licensing keys (intended for large organizations, not individual resale), which carry risks.
Key Details
Bind to MS Account: The key should permanently appear under your Microsoft account's "Services & Subscriptions" page after redemption at setup.office.com. This allows for easier reinstallation and management.
Perpetual Use: The license is a one-time purchase, not a subscription, and is designed for a "lifetime" of use on a single PC.
Transferrable: You can transfer the license to another computer you own (or even another person in the EEA, subject to conditions), but you must first uninstall it from the original device. Microsoft's terms allow this transfer not more than once every 90 days, except in cases of hardware failure.
Genuine Retail Key: The description claims it's a genuine retail key. If purchased from a legitimate and authorized reseller, it should be. The "Professional Plus" version, however, is primarily a volume license product, not typically available as a single-unit retail purchase directly from Microsoft's website.
Global Activation/Instant Delivery: These claims are common for digital product sales and are standard practice for online software vendors.
Strictly for Windows OS: Office 2019 Professional Plus is only compatible with Windows 10 or 11 and does not work on Mac operating systems.
