Skype for Business Onlie required Ports



I need help to get a list of required Ports for Office365 / Skype for Business Online, the mentioned ports in the Admin Guide of Polycom 8800 Trio seems to be for Skype For Business On-Prem.


Many thanks.

Hello Samo,

Polycom only qualifies against the Platform and all ports etc. are standard as defined by our partner Microsoft®.

You therefore may want to reach out to the Microsoft® community and / or Microsoft® support directly instead as this is the most direct and efficient path.

Please try here

Best Regards

Steffen Baier
