Ok, this gets asked a lot because some companies have the policy of not allow their employees to archive mail to a .pst and the message from the Exchange server says:"You may not be able to send or receive new mail until you reduce your mailbox size. To make more space available, delete any items that you are no longer using or move them to your personal folder file (.pst). Items in all of your mailbox folders including the Deleted Items and Sent Items folders count against your size limit. You must empty the Deleted Items folder after deleting items or the space will not be freed."
So, the old way of doing this was hiring MCS to come in and modify a couple of .dlls so that the text said something different. But if those .dlls got updated in a service pack, you had to do it all over again. Plus, if you called into Microsoft Support and said that you got the error: "Your mailbox is too large. Clean it up." The response would be: "???? I've never heard of that error. That isn't in our code..."
Then we released a fix that would allow you to turn off all mailbox size limit messages. How to disable mailbox size limit warning messages on an Exchange 2000 Server computer. This was included in Exchange 2003 SP1 and also could be found in the Exchange 2000 Post SP3 roll-up. But this was an on or off thing. Administrators sometimes want the message to be sent. They just want it to say something else.
Then Jason Nelson announced the release of the Exchange Quota Message Service. This is a separate service that can run on your exchange servers and send out custom messages. Its source code is available under the Microsoft Shared Source License. It isn't supported by PSS\CSS. It currently has been updated to allow for easier installation than before.
Wouldn't it be nice if this or something similar was included in the product?
