Description of Impact
Some BU clients with access to Microsoft Office 365 services were encountering an issue where instead of being prompted for Duo 2 Factor,encounter a Microsoft multifactor authentication prompt instead. This issue is likely attributed to the Duo option being inadvertently removed, in which case Microsoft pushes the client towards their Multifactor security option.

IS&T teams have identified the cause, and are working on a backend update to prevent clients from making this inadvertent removal moving forward.
