Get Access to Microsoft Dynamics Marketing’s Functions

The first time you sign in as the site administrator you will have limited privileges to only access the administrative options (more noticeably you'll only see the "Settings" tile when you click "home") 

User privileges are defined for each User ID and determine the Microsoft Dynamics Marketing features available to your user. User Privileges that are available are different depending on the User Type. 

To update your user privileges, from the main navigation panel click Home - Settings - Users


Click the user you want the adjust permissions for. The Default user will be "MPADMIN"

You can then select the appropriate “Role” permissions from the "User" screen.


 
As an example lets add "View All" and "Edit All" priveleges to "Landing Pages", "Lead Management" and "Marketing": 

  

This will add the "Marketing Execution" tile to your navigation.

If you need access to all areas of Dynamics Marketing you can click Grant All

If you have more users who'll need access to Dynamics Marketing, you can go ahead and create them, and assign priveleges to them like described above. A user wont be able to login to Microsoft Dynamics Marketing without User privileges assigned.
