Unable to join Skype for Business/ Lync meeting remotely using Mac Book.

Issue: Unable to join Skype for Business/ Lync meeting remotely using Mac Book.

Problem statement:

Recently I came across very strange issue. Skype for Business/ Lync Meeting join was working remotely using windows computer/laptop, Mobile app however meeting join was NOT working using Mac book..


There was no issue when Windows client join meeting means external meeting Join URL and reverse proxy was working.

Also Skype for Business meeting join was working correctly internally using Mac Book hence there is something wrong externally or on Reverse Proxy only.

Hardware load balancer was working correctly and all required port was open on external firewall hence concentrated on Reverse Proxy server.

Even Reverse Proxy was working because remember windows client was able to join meeting correctly so this was strange issue.

Hence I reset the IIS on reverse proxy server. (I use IIS ARR for Reverse proxy)


This actually did the trick and meeting join started externally using Mac Book.

I don’t know what was different when Mac Safari browser was joining meeting.  Looks like when I try to join the meeting using Mac, this was quering the meeting URL which will go through the reverse proxy, here it might not activate the Lync client and the traffic will flow through the reverse proxy, joining a meeting might fail if there are any issues with the reverse proxy.


Thank you.

How to provision user to use Skype Meeting Broadcast meeting as presenter?
·        Assign the appropriate license once AD user showed up in Office365 Tenant.
·        User must be enable on Lync or Skype for Business enable to use rich feature provided by Skype for Business/ Lync Server.
·        Grant external access policy with Public IM connectivity (PIC) access in order to present Skype Broadcast meeting.
Note: Keep in mind if you are using Skype for Business/Lync On-Prem then you have to have enable PIC to user who is going to use Skype Meeting Broadcast as presenter, event, producer etc.
Incase user don’t have PIC access policy then,
If user is not enable for PIC (Public IM connectivity) then when user Join Skype Meeting Broadcast as presenter/organizer then they will get error. “An error occurred during the Skype Meeting.” 

When you open UCCAPI log in snooper then you will see Forbidden access.

In order to resolve this we must assign external policy with PIC access the user who presenting / organizing Skype Broadcast Meeting.
Using PowerShell:
PS C:\> Grant-CsExternalAccessPolicy -Identity "bilag" -PolicyName "Allow Federa

tion+Public+Outside Access"

Using Control panel:
Lync Control Panel > Users > find user and select external access policy as “Allow Federation+Public+Outside Access”

Click on OK. 

Sorry, we were trying to get some info about your company’s policies but could’t.
User will get this error when user does not have Office365 license assign.
Login to the Office365 portal > Users > Active Users > Select user and edit and assign appropriate license.
