I have been getting odd errors over the past couple of weeks where assorted people outside of my organisation have been having mail bounced back when trying to send to some mailboxes on my domain. The DSN's are telling the sender that the Exchange mailbox/user has exceeded their storage allocation.
This is strange in that I have only set a 'soft limit' on the mailboxes in my domain. The user receives a notification but the mailbox is still allowed to send and receive mail at all times. Also, upon checking the mailstore sizes for the accounts concerned I found that they were not actually at the limit anyway!
I have included the text from a DSN below:
