VVX Exchange only works when logging in through computer

When logging in using credentials or PIN on the phone the Exchange features do not work. It only works when pairing with the client. Is this is a known issue or limitation of the phone?

Hello EPJR,

welcome back to the Polycom Community.


Did you ever solve your initial issue => here <=

In addition 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 "Read First"

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


Also are you 100% sure you are adding the credentials the same as on the LYNC / Skype client?


And no Exchange will never work using Pin & Extension. This is per Microsoft design.

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

Best Regards

Steffen Baier

It looks like my initial issue was related to this. I wasn't able to get the phone to work properly without logging out first though.


I retested the phones and it looks there is still some issues with the older firmware but I'm happy as long as it works on the new version. I must have mixed up the scenarios. Using credentials is working.


Thank you for the information.
