"Access Denied" error when you use the connect-MSOLService cmdlet to connect to Office 365
Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.
When you try to use the connect-MSOLService cmdlet in the Microsoft Azure Active Directory Module for Windows PowerShell to connect to a Microsoft cloud service such as Office 365, Microsoft Azure, or Microsoft Intune, your attempt is unsuccessful. Additionally, you may receive the following error message:
Connect-MsolService : Access Denied. You do not have permissions to call this cmdlet.
This issue can be resolved by adding the member/user to an administrator role within Azure. For more information, see the article Add-MsolRoleMember.
