It would be nice if Outlook provides an event for incoming email. I have checked the list of supported events at https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/autolaunch . Strangely i couldn't find an event which accurs when a new mail arrived.
I am requesting this feature because i am working on a add-in on which i want to perform certain actions on the incoming emails like mark it read or move to a certain folder etc.
