No mails can be sent to a "Shared Mailbox - Why?
Each "Shared Mailbox" can be equipped partly with different rights, so-called "associations". For the management of a "Shared Mailbox", three associations "MOF", "OWN" and "SAS" are available. Sometimes the wrong use of these associations may cause problems. For further information, see the manual
