Hey,
We are developing a COM based Office addin. We encountered a situation where we need to prevent Office from displaying the "Save-on-close" message box.
According to the documentation here: https://docs.microsoft.com/en-us/office/vba/api/powerpoint.presentation.saved , changing this property to msoTrue should prevent the message box from appearing when the user closes a document.
Unfortunately, changing this has no effect. We see that the value of the Saved property changed by trying to get it, but the message box still appears.
Is this is a known bug? If so, how can we report it?
Thanks!
