We use Microsoft Dynamics CRM 2016 with December update installed and Exchange 365 in our company. We have configured ADFS with the Add-AdfsClient command to allow CRM App. We also have all mailboxes enabled and configured to Server-Side configuration. They have Use Dynamics 365 App for Outlook privilege. However, none of these mailboxes is visible in All Eligible Users view in CRM (Settings -> CRM App for Outlook). Also, none of the users sees the web app in his Outlook.
What should we do to make CRM App for Outlook visible and working?
Many thanks, Jiří
