Escalation – Activation Failure After Over-Registration Beyond Documented Limit (Office Home & Business 2024)

Hello,

We are a Microsoft reseller based in Korea, and we would like to formally escalate an issue regarding Office Home & Business 2024 product key registration and activation behavior.

Our end-user customer purchased 40 legitimate licenses, and 30 product keys were registered under a single Microsoft account.

Prior to purchase and deployment, we clearly informed the customer that a maximum of 25 product keys can be registered per account. However, the Microsoft system allowed registration of up to 30 product keys without any restriction or warning.

The critical issue is as follows:

• Registration of product keys was permitted beyond the stated limit (25 keys)
• However, activation failed starting from the 26th installation onward
• This has resulted in 5 fully purchased licenses being unusable

From the customer's perspective, this behavior is inconsistent and misleading, as:

• If the actual enforced limit is 25, the system should have blocked registration beyond that limit
• Allowing over-registration without restriction but restricting activation creates unexpected service failure and customer impact
• There was no system-level warning, validation, or enforcement during key registration

As a result, this issue is not solely attributable to user behavior, but rather appears to be a system design limitation or inconsistency on Microsoft’s side.

🔍 Impact

• The customer has paid for 40 licenses in good faith
• 5 licenses are currently unusable
• This is causing customer dissatisfaction and trust issues toward both Microsoft and the reseller channel

📌 Requested Actions

We strongly request Microsoft to provide one of the following resolutions:

1. Enable activation for the remaining 5 licenses
2. Provide a method to separate or reassign already registered product keys to another Microsoft account
3. Offer an exception-based activation support or backend adjustment
4. Provide an official explanation and documented limitation policy regarding:
   • Registration limit vs activation limit inconsistency
     • Expected behavior in such scenarios

⚠️ Additional Concern

This issue raises a broader concern regarding lack of enforcement and transparency in product key registration policies, which may lead to repeated incidents across other customers and partners.

We request urgent review and resolution of this case, as the customer is currently unable to fully utilize legitimately purchased licenses.

We look forward to your prompt response.

Sincerely, Moved from Microsoft 365 and Office | Install, redeem, activate | For home | Other
