Cisco Unity OAuth2 configuration

[BoBo1]

Hello,

We had Cisco Unity configured to send email using Basic authentication and it was working fine. We recently upgraded the server to allow for OAuth2 to be used, but it is have connection issues. 

I followed the steps for M365 in this link https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/12x/unified_messaging/b_12xcucumgx/b_12xcucumgx_chapter_01.html#id_25193, but it still won't connect. Also, lots of these steps seem to be using features that I understand will be deprecated on Microsoft end soon. Is there more recent instructions? 

When I test the connection it gives the failed connected to Exchange CAS server errors. If I switch it back to basic everything works fine.

Any ideas?

I was able to get this going.

Cisco support had me check the user sign-ins for the UMS account in Azure AD and the application was failing to sign in due to a failed secret id provided. I generated a new secret ID and applied it in Cisco Unity and the system connects now.
