Dear Friends
We faced an strange problem after Lync 2013 fully implementation, would you give us any issue to solve this problems
1- Whiteboard works about 30 minutes each time after Lync server restarting, for internal and external user both, and after that, it stops and give an error says“An error occurred while presenting”
2- Totally we face “An error occurred while presenting” by PowerPoint sharing
3- The call communication among two users that are both outside of domain is possible but the same call communication among a user inside domain and one outside of domain could be established , we added the user outside of domain the certificate and also in host etc, relevant IPs is added.
We are in desperate need of a solution or guidance for this problem.
