Assign required roles to your user

Assign one of the following roles to your User:

• Global Reader (recommended): this allows you to read all roles needed.
• Exchange Administrator and Teams Administrator: user needs both roles but with this roles you can access to the same information as a Global Reader (here you only read so that's why we recomend that role).

Follow these steps to assign the role:

1. Go to Users > All Users > Click on the email for the user you will use

   

2. Click Assigned Roles

   

3. Click on Add assignments, then search and select:

   • Global Reader This is the recommended, if you want to use the others just search for them

   

4. Click on next, then assign the role as Active, and click on Assign to grant admin consent

   

Warning

Remember that if the user is newly created, you need to sign in with that account first, as Microsoft will prompt you to change the password. If you don’t complete this step, user authentication will fail because Microsoft marks the initial password as expired.
