The NHSmail Microsoft 365 (M365) service delivers an integrated service offering between NHSmail infrastructure and the M365 suite.

This document has been created for IT managers and Local Administrators (LAs) within health and care organisations, to provide information on frequently asked questions about the NHSmail M365 service.

M365 Applications

Will users be able to invite external guests to access M365 content?

The Azure B2B Guest Access Service supports the invitation of external guests to access NHSmail M365 applications including SharePoint.

The external guest must be a member of an organisation whose domain has been added to the ‘allow list’ on the NHSmail platform. Guests may only be invited by NHSmail users who are configured as Eligible Guest Inviters by their LAs. Organisations and their external guests will be required to complete a Partnering Agreement along with NHS England. The Partnering agreement will be sent once an application has been made. As part of the application process, the external guest organisation must also conform to DSPT. Following the invitation and application process, the external guest will be able to access the SharePoint content using their own credentials. All guest accounts will have access to Azure AD / M365 for an initial period of 30 days. Following this, the guest user will be required to obtain approval from an NHSmail user to retain their access for another 180 days (this process is repeated every 180 days).

Further information is available in the B2B Guest Invite User guide.

Will Azure Active Directory Business-to-Business collaboration capabilities be available?
