An error occurred during the Lync meeting when open meeting the first time.

Question

Hello Lync specialists out there! We are running a Lync 2013 standard server in our company together with edge server and reverse proxy for external access. We haven’t taken Lync meetings, because of missing licenses, official in use but
while testing I’m experiencing already a problem. When I schedule a meeting in Outlook and the click the link the Lync 2013 opens a window and wants to connect me to the meeting. Anyways after some period of time I get a message saying: “An error occurred
during the Lync meeting.” Then when I close this window and click the link again in Outlook it works like a charm right away. Is there anything I can do that this will work from the beginning? Also when I then try to open this meeting room several times it
works but e.g. on the next day or after some hours I’ve the same problem again.
Thanks for your great input already.
Regards
Robert

Hello,
thanks to Adrian first for informing about the September update. Quite strange that they have released two updates in such a short period of time. The last one was January 2014 and then August and September. Luckily we have just a small
environment and the update is not a big issue.
The update is now installed and I would have to monitor the situation the next days.
Holger which settings I should enable in the meeting policy? We have two policies for conferencing at the moment. First one (default) for all users which disables conferencing as we have only standard licenses for them and a policy with
enabled conferencing for users with enterprise CALs. The conferencing policy for enterprise users looks like that for us:
