Dear All,

We have a lot of ploycom trio and we try to configure exchange in order to have meetings on polycom device to allow the user to join the meeting from polycom.


I've follow the instructions on stupe guide but doesn't work.

I've enable debug logs and there is error message..

Please note that we are in a hybrid mode regarding exchange configuraiton (we have a exchange 2013 on-premise connected to office365 exchange where all rooms has been created)


I've capture network trafic from polycom device and there is no trafic to exchange 2013 or office365 .. i've configure my on-premise server url, as autodiscover pointed to our exchange 2013 not to office365


Thanks for your help,

Hello Irib,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


In addition the Polycom community is not a replacement for our standard support organisation so any issue needs to be reported the correct channels.

In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you. End Customers are usually unable to open a ticket directly with Polycom support.

If this is some sort of an Internet discounter please post either your phone's MAC address or your Polycom devices serial so I can look up who would be able to support you. This may not be who you purchased the Polycom device from.


This includes potentially providing access to test accounts or remote access into your network.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
