I am working on an Outlook extension that requires making a change to a MailItem open in a compose window if the SendUsingAccount property is changed via the GUI. I would like to be albe to apply my changes automatically, but I cannot find any events that are raised when the user makes the change. I have tried listening to the following events with no success:
- mailItem.PropertyChange
- mailItem.CustomAction
- mailItem.CustomPropertyChange
Are any events raised when the SendUsingAccount property changes?
No, is the short answer.
You could hack up a timer to check for the change on the property.
