This issue occurs for one of the following reasons:

  • You enter an incorrect user name or password.
  • You try to sign in to the service by using an account that doesn't have access to Exchange Online.
  • You have security defaults enabled in your tenant.


To resolve this issue, use the Exchange admin center in Microsoft 365 to add the user as a member of the administrator role group. To do this, follow these steps:

  1. Sign in to the Microsoft 365 portal (https://portal.office.com) as an administrator.
  2. Click Admin, and then click Exchange.
  3. Click permissions, and then click admin roles.
  4. Double-click the role group to which you want to add the user. For example, if you want the user to have full access that includes Windows PowerShell, double-click Organization Management.
  5. To add the user to the list, click Add ( ) under Members.
  6. Click Save.

If you have security defaults enabled, see Connect to Exchange Online PowerShell using modern authentication with or without MFA.
