Using Classic Outlook on Windows for personal email, calendar, and contact management
To reinstall Outlook 2016 on a new Windows PC without Microsoft 365, use the original Office/Outlook 2016 license and installation source that was associated with the old computer.
- If Outlook 2016 was part of Office Home & Student, Home & Business, or Professional 2016 (one-time purchase):
- Go to https://account.microsoft.com/services and sign in with the same Microsoft account that was used to redeem/activate Office 2016 on the old PC.
- In Services & subscriptions, locate Office 2016.
- Use the install option there to download the Office 2016 installer, then run it on the new computer to install Outlook 2016.
- If activation fails on the new PC, use the phone activation option as described in the article “"Telephone activation is no longer supported for your product" error when activating Office.”
- If Outlook 2016 was installed as a standalone product (not part of a suite):
- Use the original product key and Microsoft account that was used to redeem it, then reinstall from that account in the same way as above.
- If Outlook 2016 came from a Microsoft 365 subscription:
- That subscription normally installs the current Outlook version, not Outlook 2016. To keep using Outlook 2016 specifically, a valid Office/Outlook 2016 one-time license is required as in steps 1–2.
- If the old PC still appears as an installation:
- Because the old computer crashed, simply install on the new PC using the same account. One-time Office 2016 licenses can be transferred to another computer owned by the same person in case of hardware failure.
Regarding iCloud storage:
iCloud storage does not provide extra disk space on the Windows PC for installing Outlook. Outlook 2016 must still be installed on local disk. iCloud can sync mail, contacts, and calendar, but it will not increase the available local storage for installing Office/Outlook.
If Outlook 2016 will not open or behaves incorrectly after installation, uninstalling and reinstalling the Office/Outlook 2016 desktop apps from the associated subscription/account typically resolves the issue.
