We recently deployed Dynamics 365 on-premise. We are using ADFS 3.0 for authentication. Everything works fine if I browse to the Dynamics URL (crm.company.com) in a web browser.
We deployed the Dynamics 365 App for Outlook to a couple test mailboxes. When we click the Dynamics 365 button in the Outlook toolbar a "Windows Security - iexplore.exe" authentication prompt appears. The problem is that the wrong info is listed in the prompt. Instead of "Connecting to crm.company.com" it is trying to connect to the CRM server FQDN, e.g. "Connecting to crmserver.domain.local". We are not able to get past this authentication prompt with any credentials.
Does anyone know how we can change the App for Outlook to connect to the web URL and not the server FQDN? Thank you.
