I have this absolute weird behavior for some mails that are sent through the SQL 2008 Database Mail:
They are only delivered on OWA by webmail and deleted shortly afterwards through synchronization with any open Exchange connection (Outlook/Smart Phone). If there is no such connection open, they last...
I have a couple of triggers in SQL that -based on some queries- launches the database mail; this generally works fine, but there is one rather complex query that leads to this behavior. The query is correct and the content in generates apparently as well. If not, why would it be delivered to OWA? Where lies the difference? We are running Exchange Server 2010
