We are aware of an issue currently affecting the Intune service, where administrators are being prompted to re-authenticate approximately every 1 hour.

We are actively working with Microsoft to investigate and resolve the issue.

Impact

Administrators may be prompted to sign in more frequently than expected when accessing the Intune admin centre.
Some users may encounter intermittent authentication errors during this process.

Workaround

If prompted, select “Sign in again” and complete the authentication process as normal.
If you receive an error stating “experiencing authentication issues”, please sign out fully, then sign back in and retry authentication.

What you need to do

No further action is required at this time beyond the steps above.

We apologise for any inconvenience caused and thank you for your patience while we continue to work towards resolution with Microsoft.

If you require further assistance, please raise a ticket via the Helpdesk or contact helpdesk@nhs.net.
