See also Connect to Exchange Online Using Remote PowerShell (© 2020, Microsoft Corp, available at https://docs.microsoft.com/, obtained on February 3, 2020)

Run the PowerShell script mentioned in the Microsoft article on the Orion server, not the target node.

Credentials

  • An Orion account with SAM administrator permissions.
  • An Office 365 account with Global Administrator privileges.
    An alternative account with an admin role can be used if it meets the following requirements.
    • The account must be a member of an Office 365 admin role.
    • The account has adequate rights to subscriptions and management groups, as well as access to the Office 365 API.
    • The account should be an all-in-one, inclusive account to support the monitoring of all mailboxes.

Use UPN format (username@domain) — not domain\username format to enter credentials. Also, a service account for Exchange Web Services is recommended to avoid authentication issues when passwords are updated.
