Symptom

The Viva Sales app is unable to communicate with Dynamics 365, but the user can access Dynamics 365 directly. 

Root cause and resolution

Root cause

If the Dynamics 365 organization has two-factor authentication enabled, but Microsoft Teams does not, the Viva Sales app for Teams will be unable to communicate with Dynamics 365. This is intended to prevent security incidents. When Dynamics 365 has two-factor authentication enabled, any communication from users that logged into an app without two-factor authentication will be considered as untrusted.

Resolution

To solve this problem, you must perform one of the following actions:

  • Enable two-factor authentication in Dynamics 365 and Teams. This is the preferred action.

  • Disable two-factor authentication in Dynamics 365 and Teams.
