We are using on-prem SysAid v23.3.40 b5 and Exchange online

As most of you are aware Microsoft will be deprecating basic authentication for email next year.  The solution is to use modern authentication like Oauth.  

We have had our SysAid setup to use Oauth2 for quite sometime now, but noticed in Exchange mail flow reports that my helpdesk account is using basic authentication.  

Any idea how this is possible?   

***update***  

after doing some digging,  I noticed in 365 sign in logs that sysaid account is using the authentication protocol ROPC (resource owner password credentials).  which confirms sysaid is not using full OATH2 with modern authentication.

Is there a misconfiguration on my side or is this an issue within Sysaid On-prem?

Thanks for the help!
