Hi,
Sorry about the issue you're going into. If the "Upload Files" button in Word's Copilot is grayed out, it’s usually due to one of several common issues. First, make sure your Microsoft 365 Premium license is active and properly synced, go to File > Account > Update License. Next, confirm you're signed in with the correct account that holds the Copilot license, especially if you use both personal and work accounts. Then, check your privacy settings under File > Account > Manage Settings and enable all connected experiences. Also, Copilot requires the Current Channel or Monthly Enterprise Channel, if you're on a different update channel, some features may be unavailable. Finally, keep in mind that Microsoft is still rolling out certain Copilot features, so availability may vary by region or account type.
Kind regards,
