It isn't 100% certain yet but when the user running the job queue was connected to the office network the Job Queue would send emails just fine, but when the user was outside of the office it failed.
Please follow the steps provided below:
- Explicitly sign out of business central (not just closing the browser window)
- Clearing all cookies, closing all browser windows.
- Sign in again, which should prompt for MFA.
- You can also try using a private browser session.
If this doesn't work, the tenant admin should try to revoke MFA sessions from the Azure portal for the user having issues.
After revoking sessions, you should follow the same steps above.
As a final mitigation if the above still doesn't work, the tenant admin should try to "Require re-register multifactor authentication" instead of just revoking the MFA sessions, which would cause the user to need to setup their MFA again.
Then you should once again follow the steps above (sign out, etc.)
