I'm integrating the CUC with MS Office 365 and hit some stone currently.
The client is running on Mac environment, so they do not host ANY MS server locally and hence we can't installed any IIS to act as SMTP relay.
My understanding is that, CUC need to communicate with the SMTP proxy/relay, and that the configured single inbox will work.
What are the approach/ or, how can i overcome this?
Yes, the client is using Exchange 365 (cloud) services.
Can you elaborate more? How can the local UC connect to a cloud based Exchange 365?
I'm abit confused on this.
I've read this doc before, and it stated that a SMTP proxy is required for Single Inbox.
"If you want to select Relay the Message or Accept and Relay the Message for either list, you must first
configure an SMTP Smart Host on the System Settings > SMTP Configuration > Smart Host page.
Connection Administration will not let you save a new unified messaging configuration with those
settings when no SMTP Smart Host is configured. For SMTP smart host server, Connection will
communicate with on -premise SMTP relay servers only"
The environment is a MAC environment, and there's no single Windows platform machine.
Relay the Message or Accept and Relay is not the same Single Inbox. This basically means if I want Unity Connection to record a voicemail, then after its done, forward to say firstname.lastname@example.org *then* I would need an SMTP relay server. It could as simple as their ISP SMTP server. But since you are using Single Inbox, the SMTP Prox address needs to match the Exchange365 email account. Unity Connection will have SMTP Proxy as by default the unityserver.company.com. This does not work well for replies once in Outlook/Exchange. Update this to show company.com as the smtp.
