Modern Authentication is enabled at the tenant.<br />
Enabled one user with MFA within Office 365<br />
Without any additional Claim Rules MFA seemed to work for ADAL client (Outlook 2016)<br />
<br />
Created App password and attempted to use it for legacy ActiveSync client.<br />

Any ideas?<br />
