Does the Word JavaScript API support event detection for an autosave on or off event such as when autosave gets turned off for a document issue?
I can see Excel supports it as mentioned here: https://docs.microsoft.com/en-us/office/dev/add-ins/excel/excel-add-ins-events
If the API you refer to is Word WAC API, I'd say no. The Event on WAC is a part of recent works and will be released progressively. However we can't give out an explicit timeline of it for now. Thanks.
