How to configure Cardiris for Microsoft Dynamics CRM

All the settings above only need to be set once. The next time you
connect to your CRM server, Cardiris remembers your settings.

When the CRM server has been configured you need to
configure your CRM field mapping.

Click the tabs Leads, Contacts or Accounts depending on
which entity type you want to configure.
Note that field mapping is entity-specific. This means the
configuration process must be done separately for Leads, Contacts
and Accounts.
General note: the configuration may take some time, depending
amongst others on the network configuration and the proxy settings.
