Hi Stephen,
To enable Microsoft 365 connected experiences, you must change the privacy settings inside any Office app itself, not in Windows settings or on the Microsoft account website. The option is controlled at the app level and, in some cases, by organizational policy.
Open an Office application such as Word or Excel, then go to File > Account > Account Privacy > Manage Settings. In the privacy settings window, turn on “Optional connected experiences” (or “Connected experiences”, depending on the version). Accept the changes and fully close the Office app, then reopen it for the setting to take effect.
If the option is greyed out or missing, that means one of the following applies: the app is signed in with a work or school account that is governed by an organization, a group policy or registry setting is enforcing the restriction, or the Office version you are using does not support optional connected experiences. In managed environments, only an IT administrator can change this setting.
Once enabled, connected experiences such as Dictate, Editor, Designer, cloud-based templates, and certain AI-powered features will begin working automatically. If they still do not appear, confirm that you are signed in with the correct account and that Office is fully updated.
