The NHSmail team are carrying out an infrastructure change over the coming week starting Friday 3 September and completing Saturday 4 September. These changes are not expected to cause any user impact to NHSmail or O365 services.
However, there is a potential risk of disruption to any applications using the NHSmail Relay that have hard coded IP addresses instead of using the relay.nhs.uk hostname. Guidance for this can be found here.
You may also wish to review your organisation business continuity plan should there be an unexpected impact.
If you need additional help, the NHSmail helpdesk is available 24 hours a day, 7 days a week on 0333 200 1133 or firstname.lastname@example.org.
