It
would be nice if you could type these in easily in the EMC, but
unfortunately, these are some of the features they left for the EMS.
The cmdlets you want to use are New-SystemMessage, Get-SystemMessage, Set-SystemMessage, and Remove-SystemMessage.
To
create the correct message, use the WarningMailbox message (for
mailboxes that are exceeding their warning threshold), the
ProhibitSendMailbox message (for mailboxes that can no longer send
email), and the ProhibitSendReceiveMailbox message (for mailboxes that
have completely maxed out and can no longer send or receive).
Logically, there are more parameters you can use in relation to
mailboxes or Public Folders. There are plenty of messages; however, for
now, we focus on the ones that relate to the database.
Let’s
say you want to customize the WarningMailbox quota message. You could
open the Exchange Management Shell and type the following:
New-SystemMessage -QuotaMessageType WarningMessage -Language EN
-Text "Your mailbox is almost full and you should consider deleting
items from your mailbox as well as your deleted items folder."
Now,
this message is close to the real message, but it’s just an example of
what you could use. You have to determine what you want. To learn more
