How to obtain email non-delivery report records

Registered IT support staff can obtain NDR logs by raising a request with our Service Desk. Please include the following information in your request:

  • Date (and time) range to be investigated, in a clear format such as YYYY-MM-DD hh:mm:ss
  • A sender address and/or recipient address to be matched
  • A subject line to be matched, if available
  • The basis of your investigation that requires and justifies provision of NDR logs

We may require approval from the Information Compliance Team if your request appears to have privacy implications, and may reject your request if the basis does not appear to justify the enquiry.

NDRs for messages sent from other Oxford systems or from outside of Oxford will typically be recorded by the mail relay service. These records will normally be available for up to 90 days and can be examined quickly onsite.
