I've been working all week to get unified messaging working again. We had is setup with our on-premise exchange server 2013. We migrated to Office365 and I created a new Unified Messaging service and followed the documentation to set it up. I created an application, created a new user in the cloud and gave that user application impersonation role and assigned that user to the application. Following the guide I applied appropriate API permissions. I can't see that I missed a step, but I'm still getting errors. I followed troubleshooting steps and can see SSL communication between Unity Connection and Microsoft. It ends with the Unity Connection server sending an Encrypted Alert (21). To the best of my research, that's just a simple error message that is of course encrypted. I have wiresharked and looked at logs and cannot determine the issue. Attached is a screenshot of the test and a snippet of the logs i've pulled.
I am really starting to think there is a bug in 12.5 (SU6) or maybe it just isn't supported.

According to the current documentation for how to setup a messaging service with O365 it should be supported. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/12x/unified_messaging/b_12xcucumgx/b_12xcucumgx_chapter_01.html
That said I would recommend you to upgrade your CUC to either 14SU3 or later as that changes the integration with Exchange O365 to not rely on the old outdated EWS service and that the 12.5 version is soon to be EOL.
The changes in the integration are outlined in these documents.
Likely already known, but if not youāre needing to get to version 15 pretty soon as the underlying operating system in 14 and earlier versions is going EOS pretty soon. In the meantime you might want to consider upgrading to the latest SU release of 12.5, if Iām not wrong itās now SU8 or maybe even SU9. Given that the upgrade of CUC is pretty quick and straightforward it shouldnāt be too much effort, at least if youāre not using any additional locales. If you do the upgrade is a little more complex, but still on the easy side compared to other CVOS systems, like for example CUCM or CUPS.
My comment on that the document specifies that it should be supported was based out of that you wrote in the specific response that youāre using 12.5 SU6. It may be so that 12.5 SU5 isnāt supported anymore as you yourself suspect. As I mentioned before itās advisable that you get the system updated to the latest SU release instead of spending time on continue trying to get it to work with the SU5 release.
Not related to the name lookup, have you downloaded the certificates for O365 and uploaded them to the Tomcat trust store on your CUC system?
