Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
If the license is a one-time purchase of Office such as Office Home & Business, Office Home & Student, or Office Professional, use this process:
- Uninstall Office from the old laptop.
- Install Office on the new laptop.
- Activate it on the new laptop using the same product key.
- If activation says the maximum number of activations has been reached, activate by phone.
For Office 2024 or Office 2021, the license can be transferred to another computer that belongs to the same owner, but not more than once every 90 days, except in the case of hardware failure. When transferring to a new computer, the software must be removed from the prior computer and no copies may be retained.
If the old laptop failed and Office Home & Business 2021 was on it, install Office on the new laptop from https://account.microsoft.com/services. If activation issues occur, Microsoft support may be required.
If the license is Microsoft 365, there is no transfer process in the same way. Sign in with the Microsoft account used for the subscription and install Office on the new laptop.
