Trio 8800 Skype on-prem and Exchange on-line



Maybe you can help me with an advice regarding the following setup:


Lync 2013 on-premises

Exchange on-line (O365)


Sip address is something like: and connects to on-premises only Lync 2013 server

Email address is something like: and should connect to O365 to grab calendar data


In Trio8800 there is a unique place where you can configure the connection details and is common for Lync/Exchange (I think) - see attached.


What is working: entering the Sip address in he "Sign-in Address" field and the on-prem: "Domain", "User" and "Password" the Trio device connects to Lync and is working fine

What is not working: in the setup mentionjed above, the Trio device cannot connect to mailbox to grab calendar.


Any clue about this? (I know it is a complex setup, but that's it for the moment...)


Thanks a lot.

Hello Soring,

welcome to the Polycom Community.

At the moment the Trio is working as designed as we currently do not support separate credentials for Exchange.


I spoke to our Microsoft Guru and he came back with this:


  • Mismatched SIP URI and SMTP addresses can create all sort of issues outside of the Trio itself.  This is a poor practice overall that will have several limitations.
