I need to implement functionnality in C# .NET to save some messages (that users send using Outlook, they call those messages Tickets) .
When a user would finish writing the mail , I need to know if this mail is a Ticket and save it to a SQL-Server Database .
What the best approach to achieve this ? writing a separate .NET app or writing a plugin for Outlook ? and please can you point me to any ressources to help implementing those requirements .
