Cisco Unity connection with Office 365 Hybrid

I have attempted to review documentation from cisco's end regarding Office 365 and unified Messaging services and connecting it to Office 365.

In this example the mailbox would be held in the cloud and not within the on-premise exchange and on-prem exchange is just a connector.

Would it work to connect through the

Would it work to connect through the on-premise Exchange server acting as the connector or is it required to have the Unity Connection server opened up to the internet for mailboxes held in the cloud?

Hi Willium,

Talked to Cisco today about the Hybrid environment configuration and if the mailbox is hosted in cloud to achieve single inbox capability and synchronization betweeen phone and mailbox you need to connect your Unity to the internet/exchange online.

Else if you use the on prem server it can be used as a relay but does not synchronize since it just sends the email out through the server and out.
