We would like to track the timespent on email using OfficeJS TaskPaneUI. Since the outlook email works offline, there is a requirement from customer to track the time spent when its offline as well. As per office-add in documentation currently it is not possible..
I see that other office-addins(Excel,word,powerpoint) has offline support. https://docs.microsoft.com/en-us/samples/officedev/pnp-officeaddins/use-storage-techniques-to-access-data-from-an-office-add-in-when-offline/
Is there a scope to add offline support for email as well?
