Mailbox size limits in Exchange 2003

Hi All

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?

If you are over quota, then it is impossible to 'send' emails - Outlook refuses to place the messages in the Outbox.  the can be saved in Drafts, but would need to be 'sent' again after either allocating more quota, or reducing the size of the mailbox.

The check is made when the 'send' button is pressed, so Outlook is already trying to contact the Exchange server to pass on the message.  In effect, the Send Prohibit limit being reached prevents the Exchange server from receiving the message from Outlook.

So there is no chance of a user trying to send a mail when their mailbox size is 105MB, and the mail sitting in their Outlook Outbox 'waiting to be sent' until the mailbox size is reduced, and then being sent (automatically) at another time?
