The Power Platform transition
The Power Platform environment transition is required to create a new NHSmail Default environment with an updated data residency in the United Kingdom.
Please note that as part of this activity, the current NHSmail Default Environment (Europe) will no longer be the Default Environment and will eventually be decommissioned.
A new NHSmail Default Environment with an updated data residency in the United Kingdom was created on September 7th. As part of this activity, the old NHSmail Default Environment (Europe) is no longer the Default Environment and the Old Default Environment will be decommissioned on 16 February 2023. .

What do I need to do?
The Power Platform transition will only affect those who are currently using the NHSmail Power Platform Default Environment, and the impact is limited to the functionality detailed in the table below.
Before the Power Platform transition:
Please ensure that you take the necessary steps to save any relevant work as explained in the pre-transition column.
After the Power Platform transition:
Where applicable, instructions on what you need to do after the transition have also been included in the table in the post-transition column. Please make sure that you only complete them after the transition has taken place.
You will receive communications prior to the transition and when the transition to the new default environment is complete. Completing the post-transition activities in advance may mean your work will not be saved.
