หัวข้อเบ็ดเตล็ดที่ไม่เข้ากับหมวดหมู่เฉพาะใดโดยตรง
Hi Methpong Sribuajub : เมธพงษ์ ศรีบัวจับ,
I will answer you in English based on your previous message. As a friendly suggestion, posting in Thai may help your question reach a wider audience and increase the chances of receiving assistance from other community members.
Thank you for posting in the Microsoft Q&A forum.
To better understand the situation, could you please provide some additional details?
- What is the exact activation error message or error code you receive when attempting to activate Office?
- Are the affected licenses the ones that were activated directly using the product key but were never redeemed and linked to a Microsoft account?
- Can any of these licenses be found under Services & Subscriptions at https://account.microsoft.com/services when you sign in with the Microsoft account that may have been used during setup?
- After reinstalling Windows, was the hardware unchanged, or were any major components (such as the motherboard) replaced?
- Does this issue affect all licenses activated using that method, or only certain devices?
Based on your description, the issue appears to be related to Office licensing and activation records rather than the Office installation itself. The exact activation error and licensing history will help determine whether this is an activation-related issue, a Microsoft account association issue, or something that may require assistance from Microsoft's licensing support team.
I look forward to your reply.
