In the event this helps anyone else, I wanted to post this error and solution somewhere as it took me a few weeks to resolve. Issue: When trying to connect our Azure/Intune environment with our WorkspaceOne SaaS environment to manage the Intune App Protection policies within WSO, we were getting error . This occurred when inputting an O365 admin account into the credential box under Settings or Apps or Microsoft Intune App Protection Policies or Authentication tab. Solution: We had Azure/Intune Conditional Access policies in place that were blocking access to our Azure resources and applying MFA in some cases. I had to add the admin acccount to the exclusions for both policies and that seemed to work. Hopefully this helps someone else in the future.
I'm going through this issue currently. We've used a service account with Global permissions read and write abilities and everything recommended here: Configure Intune Settings however, we still get the same result. We are attempting to gain the DLP compliance for Office 365 apps. Anyone have any ideas?
@KeithHallKeithH - You will need to first add AirWatch by VMware app in your Azure AD portal as listed here: https://docs.vmware.com/en/VMware-Workspace-ONE-UEM/2005/Intune_Integration/GUID-90365FE7-E4F5-4481-...
I was facing this error despite providing the Global Administrator account during integration, following the above guide & post adding the app, I was able to complete the integration.
