When you click Test Access in the Microsoft Dynamics CRM E-mail Router, you receive the following error if you are using Microsoft Exchange 2010:
The account does not have permissions to impersonate the requested user.
Impersonation is not set up on the account that you specified on the Incoming E-mail Profile or for the user who is set up to use the Router for incoming email.
You can specify Setup Exchange Impersonation for the account that is specified on the incoming profile if you are using a forward mailbox and for individual user accounts if theE-mail access type-Incoming is set to Router on the user record. To do this, follow these steps:
Open the Microsoft Dynamics CRM E-mail Router Configuration Manager.
Click the Configuration Profiles tab.
Open the profile that has Incoming set for the direction, and then note the account that is specified in theAccess Credentials field.
