Quick query regarding mailbox size limits in 2003...if, say, I have a send limit of 100MB and my mailbox limit is at 105MB, then obviously I can't send.
However, are mails I try to send queued until the mailbox < 100MB again, or are they just deleted when I receive the NDR saying my mailbox is too full?
Also - at what point in Exchange does the message progress to? The actual Information Store, Categoriser etc? Or does Outlook 'know' that the mailbox is over the limit and Exchange is not even contacted?
