IMPORTANT - If you have an Office 365 tenant already you should NOT create a CRM Online trial the way its outlined in this guide. Instead you should start the trial directly from within your existing Office 365 tenant using the Purchase Services section (see #8 below for the location of this section).
This is your quick guide to creating a CRM Online Trial from scratch.
Friendly Name - Specify a Friendly Name to help you to identify this instance of Microsoft Dynamics CRM Online. Friendly names are especially useful when you have purchased multiple instances
Purpose - The purpose field is optional. It can help you remember what you plan to do with this instance such as testing, development, or production. Both the Friendly Name and Purpose field appear when you view your list of Microsoft Dynamics CRM instancesAccept the default values or change them. When done click the Continue button in the lower left corner (in my danish example the button is labelled "Fortsæt")
#1. Base Currency: Selecting the base currency for your organization is a one-time decision that sets the primary or default currency that is most used by your organization and the currency in which your organization does its financial reporting. You cannot complete setup without setting this option and you cannot change it after it has been set. If your organization records transactions in other currencies, you can add records using that currency, including the currency symbol and the exchange rate. When you save financial information in a record, Microsoft Dynamics CRM Online converts the monetary values to the base currency. This conversion ensures that all financial information is available in one currency for data analysis and reporting.
Next up I suggest you decide what makes sense for you to test in order to make an informed decision on how CRM Online will help your organisation.
