Requirements

When configuring NinjaOne Ticketing, the items below must be taken into account to ensure the configuration is successful and you do not receive an authentication error:

  • The account from which you send emails must be licensed with at least an Exchange Online Plan 1 License.
  • The mailbox must have “Authenticated SMTP” as an allowed email application.
  • You must have an administrator account with permissions to give consent to the NinjaOne–SMTP Microsoft 365 Application.
  • You must ensure you do not have any conditional access policies that would block NinjaOne from logging into the account.

If you have not yet enabled NinjaOne Ticketing, please see NinjaOne Ticketing: Setup and Configuration.

We recommend using an incognito / private window to perform this configuration.
