Joining meetings sent by external users.


Joining meetings sent by external users.

Hi guys.


We have not been able to join s4b/lync meetings sent to us, using our Polycom solution.

Is this not supposed to be possible? All internal meetings works fine, join button is there and so on.


But whenever we receive a meeting from an external user, then it does not accept the meeting by itself, and even if I manually do that, then the "join" button is still missing, and it will ask for a meeting number. (which wont work.)


Is there anything we can do to be able to join meeting sent from external users?




We are using a Realpresence Group 310

Software version: 5.1.0-250527

Hi pureh20,


first of all update your GS310 to fully support O365 for example. Where is your Group integrated to? Lync? SfB? How is your Group integrated in AD? As a resource or normal user? Because you can´t invite a resource account from outside your company, only  within your domain.

Hello @pureh20,

welcome to the Polycom Community.

Is this a on Premise LYNC / Skype for Business installation or a O365 online ?


I suggest you use a currently supported version like 5.1.2 if you are unable to upgrade to 6.1.x


The 5.1.2 Release notes => here <= shows:


  • GS-30315 Using a RealPresence Group system, you might be unable to join a Microsoft Lync meeting by clicking Join in a calendar entry. This issue has been corrected.

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