When a CRM instance is provisioned, a name is created for the organization – but since that name must be unique, we often see some awkward or unmemorable names – which then show up in Outlook. – But these names can be changed (even for CRM Online users) – at the client level:
To change this on a PC, close outlook and launch the CRM 2011 Outlook Configuration Wizard. Choose your organization and then click “Edit”
Edit the “Display Name” Click Ok/OK and then restart outlook – once it restarts, it will have the new/improved name in the navigation bar.
