How to activate Office, Visio, Project, Access… (Key Bind 1User,…)?
| Item | Explanation |
|---|---|
| 🔐 What is a key bind to mail? | It is a key that, when entered, will bind permanently to a Microsoft account instead of being used directly inside Office software. |
| 📧 One key per account | Once bound, the key cannot be transferred to another account. |
| 💻 Download and install Office | You can download and install Office directly from your Microsoft account after successful key binding. |
| ♻️ Reinstalling the system | Simply log back into the same account and Office will automatically activate, no need to re-enter the key. |
| 🛑 Not for multiple accounts | Each key is for one unique Microsoft account only. Do not share or resell after use. |
| ♻️ Device Transfer | Device transfer is supported but only in necessary cases, as it requires contacting Microsoft support. See instructions in the “Device Transfer” tab. |
