Solution 1Recommended

Use Microsoft Telephone Activation

Use this method to manually activate Office 2010 when the online activation server blocks your key due to hardware changes, such as moving to a new virtual machine.

When a virtual machine is deleted, Microsoft's activation servers do not automatically register that the software was uninstalled. Telephone activation allows you to explain the hardware transfer.

1
Open the Activation Wizard

Launch any Office 2010 application, such as Microsoft Word. If the Activation Wizard does not appear automatically, go to File > Help > Activate Product Key.

2
Select Telephone Activation

In the Activation Wizard, select the option 'I want to activate the software by telephone' and click 'Next'.

3
Choose Your Region

Select your country or region from the dropdown menu to reveal the appropriate toll-free support number.

4
Call and Provide Installation ID

Call the provided number. Follow the automated prompts, provide your Installation ID displayed on the screen, and clarify that the previous virtual machine was deleted so the license was successfully transferred.

Support Availability: Because Office 2010 has reached the end of its support lifecycle, phone activation availability may vary by region.

Is Microsoft Office 2010 still supported by Microsoft?

No, extended support for Microsoft Office 2010 officially ended on October 13, 2020. Users no longer receive technical support, bug fixes, or security patches.
