Any way to extend or change drag-and-drop in Outlook with VSTO?
I have an add-in I'm working on in Outlook that uses drag-and-drop to automatically save an Outlook file to a file. The problem is that the default behavior is to use the subject line of the email as the filename, and emails with extremely long subject lines send an error as there is not enough 250 character space to save the whole thing and the rest of the path.
I would like to change the Outlook migration to Explorer so that the default file name is saved in the subject line, abbreviated to 100 characters. Any pointers on where I will be doing this?
