So, we already had unity setup with Office 365 and it has been working for a while.
Config we use:
https://www.cisco.com/c/en/us/support/docs/unified-communications/unity-connection/118828-config-cuc-00.html
On 2/24 for some reason it stopped working. Tried some different settings and finally put a ticket in with MS. They started looking into it and didn't see an issue and on 3/2 it started working again with no change. Now it stopped again. As I was doing some testing I went away from the documentation and changed "outlook.office365.com" to "outlook.com" and it now connects.
Successfully connected to Exchange CAS server at (https://outlook.com/autodiscover/autodiscover.xml)
But when I do a test with a individual account it will fail and I have no idea why.
What the Log says:
Email@email.com will be accessed at Exchange CAS server outlook.office365.com - good
Diagnostic=[SSL connect error -- Unknown SSL protocol error in connection to outlook.office365.com:443 ] Verb=[POST] url=[https://outlook.office365.com/EWS/Exchange.ASMX] request=[<?xml version="1.0" encoding="utf-8"?>
The system failed to perform a typical calendar operation. - The system failed while trying to make an API call.
I was wondering if anyone else has ran into this issue?
Thanks!
