Users do not receive Microsoft Dynamics CRM e-mail messages
Applies To: Dynamics CRM 2016, Dynamics CRM Online
This issue can occur because the service account that the Email Router is running under hasn’t been added to the PrivUserGroup security group.
Perform the following steps on a computer that is a domain controller in the domain where you installed Microsoft Dynamics CRM Server.
Add the service account to the PrivUserGroup security group
Click Start, point to Administrative Tools, and then click Active Directory Users and Computers.
Expand the organizational unit (OU) that you selected during Microsoft Dynamics 365 Server Setup. By default, this is the Domain Controllers OU.
Right-click PrivUserGroup, and then click Properties.
On the Members tab, click Add, and then select the computer where the Email Router service is installed and running.
Click OK two times.
