A new community PowerShell script to simplify Exchange Server mailbox migrations has been published to TechNet Gallery and Github.
See script help for examples.
Check out the professional services provided by Granikos for planning and migrating your existing Exchange Server infrastructure to the cloud.
Exchange and other MTAs use DSNs (Delivery Status Notifications) and NDRs (Non-Delivery Reports) to notify the sender or sending MTAs (Message Transfer Agents aka Mail Servers) about the various statuses of a given email message. In Exchange, those messages are generated primarily by the categorizer component of the transport service.
You can use the New-SystemMessage cmdlet to create new messages. These messages can even be localized and can contain Html tags for properly styled notifications.
From a system perspective, the various notifications used are named and fulfill a specific purpose.
Delivery Status Notification (DSN)
A report describing the result of an attempt to deliver a message
Message Disposition Notification (MDN)
A report describing the status of a message after it has been successfully delivered to a recipient. Examples: read notification (RN) or non-read notification (NRN)
Defined by RFC 2298 and controlled by Disposition-Notification-To header
Non-Delivery Report (NDR)
A report indicating to the message sender that the message could not be delivered to the intended recipients
Non-Read Notification (NRN)
A report indicating that a message was deleted before it was read when a read receipt was requested
Out Of Office/Facility (OOF)
A report indicating that the recipient will not respond to a new message
OOF refers to the Microsoft original term „out of facility“
Read Notification (RN)
A report indicating that a message was read
Recall Report (RR)
A report indicating the status of a recall request for a specific recipient
A recall request is used when a sender tries to recall a sent message by using Outlook
