Hi!
First off this is my first post here on TechNet so I apologize if this is posted in the wrong section.
The problem a user is having is related to him not beeing able to see/share his screen/application using Lync Online from time to time. Lets call him "User A" and the external contact "User B" for this exampel.
User B shares his/her screen to User A and Users A's Lync just prompts him with the generic "There is a network issue, try again later". The next day they try the same thing (User B shares to User A) and it works flawlessly.
Another instance when the problem occured was when User A was in a larger meeting with User B (who is external). User A and his colleague was in a meeting with 30+ people and User B shared his/her screen. It worked for every one except for User A.
In my troubleshooting I've tried to share my screen/application (I'm external as well) to User A without any issue and I have shared the same to him in a group conversation, same result, it works.
Looking through the logs I found the following in the "Lync-AppSharingMediaProvider-0.AppSharingMediaProvide"-log.
8CC:1A8 INFO :: CAppsharingMediaProvider::StartLogging: tracing enabled8CC:1A8 ERROR :: CAppsharingMediaProviderSession::CompleteNegotiation - CAppsharingMediaProviderSession::CompleteNegotiation failed: lResult=-2147019873
8CC:1A8 INFO :: CRDPRTPTransportStream::Terminate - MediaManager terminates appsharing media provider session
8CC:1A8 WARN :: CAppsharingMediaProviderSession::AddAppSharingNode - no tns:InboundStream stream node

8CC:1A8 WARN :: CAppsharingMediaProviderSession::GetQoEData - AddAppSharingMetricsToReport failed hr = 80004003
8CC:1A8 INFO :: CRDPRTPTransportStream::Close - RDP session closed
I must admit that I'm not familar enough with Lync to understand this error. The What I found while googling pointed me to awnsers saying that they need a Lync edge server. But since they use Lync online I find it unlikely.
So I'd love some help with this, I am happy for what ever help I can get.
Thanks in advance
Axel
