Accessing CRM using mobiles
We have different options to access the CRM application based on the deployment model. To access the CRM application from mobile devices our CRM should be accessible from the extranet; so for example if we are working with CRM Online, we can access our organization using mobile devices without any configuration. We have different options; for example, we can directly browse CRM URLs from mobile browsers or can download native apps but, if we are using CRM on-premise or in a hosted deployment, we need to set up IFD (Internet Facing Deployment) to access our CRM application from mobiles first and then we can access it in the same way as in CRM Online.
