To obtain access to CustomerSource, please reach out to your Microsoft Partner directly. Your partner will setup your account, assign an administrator and email you the invite to initiate the process. Once your email address is associated to your account, which is done by clicking the link in the invitation email, you can login to the CustomerSource website.
The Administrator on the account can manage your account and start adding other professionals within your organization so that they can access the CustomerSource website as well.
In my next blog, you will learn how to navigate this website to get the most relevant information, so call your partner today and ask them to setup your CustomerSource account so that you can get started.
