Error Message

Exception occurred while retrieving access token. The remote server
returned an error: (400) Bad Request. AADSTS50078: Presented
multi-factor authentication has expired due to policies configured by
your administrator, you must refresh your multi-factor authentication to
access ‘00000000-0000-0000-0000-000000000000’.

Cause

This error usually occurs when Microsoft 365 requires users to reauthenticate using multi-factor authentication due to security policies set within legacy per-user MFA or conditional access policies.

Resolution

Connections from Voleer servers should be IP whitelisted so that once authorization has been provided by the user, reoccurring connections (i.e. next scheduled template job run) will no longer be MFA challenged. Follow the instructions at MFA White Listing.
