To maintain greater control over how %BRAND_YAMMER% is used in their organization, administrators can choose to enforce %BRAND_OFFICE_365_SHORT% sign-in for %BRAND_YAMMER% for all users in the network, effectively disabling the legacy %BRAND_YAMMER% identity (where users log in with email and password). After this feature is enforced, all users in the network will need to use %BRAND_OFFICE_365_SHORT% accounts for signing in to %BRAND_YAMMER%. For more information, see Enforce %BRAND_OFFICE_365_SHORT% identity for %BRAND_YAMMER% users. The %BRAND_YAMMER% app interface is shown below.
