Yes—this can mean the retailer did not activate the product key at the point of sale.
If the error is that the key cannot be found or shows as not valid during redemption, the supported checks are:
- Verify the key carefully again
Common misreads include:
- B and 8
- G and 6
- O and 0
- Q and 0
- VV looking like W
- If purchased from an online retailer, copy and paste the key if available digitally
Microsoft specifically recommends copying and pasting the key from the retailer confirmation email instead of typing it, when that option exists.
- If the error is effectively that the key is not activated yet
Microsoft states that KEY_NOT_ACTIVATED means the retailer did not activate the product key at the point of sale. In that case, the resolution is to go back to the store where Office was purchased and have them activate the product key.
- If the key still does not work after retailer confirmation
If the product key was bought separately from software and does not work or has stopped working, Microsoft advises contacting the seller and requesting a refund.
For a Microsoft 365 Personal purchase from Currys, the most likely next step is to contact Currys first and ask them to confirm the key was activated at sale/collection. If they confirm it was activated, then use Microsoft support for product key assistance.
