EWS Enabled - Calendar Not Available

Our environment: SfB On Prem, Exchange Hybrid with Okta for MFA

 

Our issue: Our Trio 8800 systems are encountering an error where they are getting EWS deployed and can connect to SfB for calls and meetings but the calendaring service is showing up as "Not Available" and thus preventing them from being able to one touch into meetings from the device.

 

Phone Software Version: 5.9.1.10906

Phone Model: Trio 8800

Serial: 64167F4EC022

 

On rooms currently logged in there is no issue but if a room goes offline for maintenance or the Polycom is disconnected for some reason it can't reconnect to the calendaring service.

The above can be used to try and self diagnose the issue or post logs for other members to try and troubleshoot this for you.

 

If this fails please go ahead and open a support ticket.

 

In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Is MFA enabled in SfB as well? If not, you will need to disable MFA on the resource accounts the devices are using to sign in. The sign-in method used for SfB and Exchange must match.
