First, open any Office app > go to File > Account. Next, open it again and sign back in, and verify the final state before changing any backup or secondary account.

Why This Can Happen

• The wrong personal, work, school, billing, or administrator account is selected
• A license, permission, connection, file rule, or local setting does not match the requested action
• Cached credentials or an incomplete synchronization or activation state hides the current server status
