Issue
When using the Office 365 workflow actions, the workflow instance suspends with the error: 'Unable obtain security token, authentication failed.'
Resolution
- Verify that the account being used does not have Multi-Factor Authentication (MFA) enabled, as MFA is not currently supported by Nintex for Office 365
- Verify that the action works with an @domain.onmicrosoft.com account vs. an @domain.com account. Success with an @domain.onmicrosft.com account vs a domain account will indicate an issue with ADFS. The Microsoft Remote Connectivity Analyzer can be used to investigate ADFS issues further.
Error Code
Unable obtain security token, authentication failed.
