UCMA 4, Lync in Office365, UserEndpoint failure

Just started with UCMA development and going over the samples. I am using our company's Lync in Office365.
In the AVCall sample in establishing UserEndpoint I am getting Microsoft.Rtc.Signaling.TlsFailureException "Unknown error (0x80131500)". In the sample (in UCMASampleHelper.cs) a Lync Server FQDN is required for UserEndpointSettings.
I am setting it to "sipdir.online.lync.com". Is it the coerrect FQDN of Lync in Office365?
If it is a correct FQDN - does the Win desktop that runs the sample need to have a specific valid certificate for Tls to succeed?Thanks,
David

As far as I know, the Lync Online systems don't support you writing UCMA applications that connect to those servers.

Windows Server 2008 (TS) and Lync Web App installation failure

Hey folks,
I've run into a little big problem due the Lync Web App installation via mstsc on a stand alone Terminal Server 2008 SP2 64 Bit. When I tried to install the Lync Web App Plugin via
mstsc and standard user I get the message:
"The system administrator has
set up a policy that the installation
prevents"
Till that it's just fine.
The next thing I did is to disable the UAC and DEP, but same problem as above. I also tried to extract the install EXE for the MSI packages to allow the installation. But did not work.
After I searched the internet for an answer relating to this problem I've had to create or change a RegEdit entry. So I switched to the registry to:
HKEY_Local_Machine\Software\Policies\Microsoft\Windows\Installer
and created a DWORD entry DisableMSI and set it to 0. Then I tried the installation of Lync Web App Plugin via
mstsc and standard user again and this message appeared:
"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2755"
Now the curious thing is, that when I am logged on locally, the standard user is able to install the Lync Web App Plugin. And it works fine. After the installation is complete I can switch to mstsc again and it works.
The only thing what doesn't work is to install Lync Web App Plugin via mstsc into the user profile.
Any suggestions?

Before you install the application, change your user mode to installation mode.
You can run the following command with Prompt Command:
Change user /install
After the application is installed, change back to execution mode, you can do so by running the following command:
Change User /Execute

Lync 2013 Client install failure

Hi
We're having trouble installing the Lync 2013 standalone client via SCCM on a couple of PCs. It is installing with no problem on most PCs.
However, on some PCs, it installs and when you launch it you get the message...
"Microsoft Lync has stopped working
A problem caused the program to stop working correctly. Please close the program."
The only option is close the program..
The event log shows an error..
Event ID 1000
"Faulting application name: lync.exe, version: 15.0.4569.1503, time stamp: 0x52b0af33

Faulting application start time: 0x01cf9f6494efc8b5
Faulting application path: C:\Program Files (x86)\Microsoft Office\Office15\lync.exe

We have completely uninstalled all traces of Office 2013 and trying reinstalling the software manually but the same thing happens. We even tried installing Lync as part of the Office 2013 install and the same thing happens (word etc does load ok, its
just Lync that fails)
Has anyone else had this happen? Any suggestions?

As this issue only happens on some PCs, so I think this problem is relate with PC.
Please check if there is Bluetooth utility installed on these PCs. If yes, try to remove it.
Update the drivers on these PCs to the latest version.

No users are being migrated to the Unified Contact Store (UCS) for Lync 2013 - Exchange 2013

I'm having difficulty getting the unified contact store to work on a migrated Lync/Exchange environment. Both servers have been upgraded to 2013 CU2, and almost everything appears to be working properly...except UCS.
By default the global CsUserServicesPolicy has UcsAllowed set to True. In that mode, none of the Lync users were being migrated to UCS, so I set the global policy to False and created a new Policy called "AllowUCS" and set UcsAllowed to True. I then
assigned that policy to myself and a couple other test accounts. Still, my contacts are not being migrated to the UCS after logging in with Lync 2013.
Other Lync/Exchange integration features are working properly. I have set up OAuth, and it tests successfully, and Lync integration with OWA is working successfully, so I know at least some communication is happening properly between the servers.
Here is what I'm getting when I run some diagnostics from the Lync server:

Anyone know what I am missing?

Hi,
Please make sure the user has been provisioned with an Exchange 2013 mailbox and has signed into the mailbox at least once.
If the user logs in with a Lync 2010 or earlier client, or if the user is not connected to an Exchange 2013 server, the user services policy is ignored and the user's contacts remain in Lync Server.
Please also check the registry key on the client computer:
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Lync\<SIP URL>\UCS
If the user's contacts are stored in Exchange 2013, this key contains a value of InUCSMode with a value of 2165.

Microsoft Exchange Server 2003 and Windows 8 Compatibility

Is there a fix or workaround for accessing email via Outlook 2013 (Windows 8) when your company uses Microsoft exchange server 2003 and has not plans on upgrading it any time soon. I am a remote employee so I am the only one that has this problem in the
company. I can access email through an owa account but it's a pain. I tried to set up a rule to have all incoming mail forwarded to my gmail account in Outlook 2013, but that did not work. Any other ideas?

If server has enabled ActiveSync you can use Windows 8 Mail Client - works almost like Outlook.
AFAIR Outlook 2013 can't work with Exchange 2003.

Exchange Server 2003 and OWA: Missing search box in contacts

Don't know what has happened here, we got a new server administrator.
Using OWA, connecting to our Server 2003 at the office. He has put the Contacts in a Public Folder that we drill down into to access. When accessing from home via OWA, and having drilled down to that public folder where the contacts reside, there
isn't a search box. In other words, if I wanted to search for a contact via OWS, I can't. I have to sift through page by page, hoping I come upon the contact.
Any help here? The new administrator seems to push this off on the guy that just left. Oy vey….

If server has enabled ActiveSync you can use Windows 8 Mail Client - works almost like Outlook.

So I see it is not only a address book issue, though it is the first visible hint you get about it. I also get the Password request window for "Retrieving Response Groups" after the log in.
I looked at similar issues, but what I found was mainly Kerberos issues, but that is not the case here, the user is able to access the folders.

Ok, I followed the procedures for 'General Application Activation' at the site Michael recommended. I'm still getting the same error:
Endpoint failed to establish: Microsoft.Rtc.Signaling.ConnectionFailureException:Unable to establish a connection. ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period
of time, or established connection failed because connected host has failed to respond 172.30.228.57:5061
at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult)
at Microsoft.Rtc.Internal.Sip.TcpTransport.OnConnected(Object arg)
The only place where I deviated was activating a port. The example uses port 6000. I entered port 5061, only
because the error I was getting specified that port. Is this correct?
I can see the application pool that I created in the Lync control panel, but its status is 'N/A' and has a red X under the Replication column. My application is also visable
under 'Trusted Application'
Any other ideas?

Lync Edge DNS Load Balancing call failure to PBX

Hi, I have an issue with a Lync 2013 Implementation involving Edge Servers and PBX calls.
We are trying to configure 2 Edge Servers using DNS Load Balancing. We configured both servers on the topology builder, assign the correct IPs, have 6 Public IPs, 3 for each Edge. Configure NATs behind an ASA firewall, then configured the name of the edge
pool and added each Edge IP for that name on the internal DNS, also checked every port and route to make sure everything works.
All the tests related directly to Lync works, IM, Presence, Audio and Video Conferencing, Desktop Sharing, etc. However, when testing out calls from the PBX System to an Lync External client through the Edge Servers, the call rings, but never connects.
Inside the network, everything works fine, even when using only 1 Edge Server and removing the other one from the topology the call connects to the external user from the internal PBX phone. I even tried it out using one Edge first and then the other to
make sure all ports were open and everything works fine using either one, but only one at the time, not both.
The issue is only present via peer to peer call, if I first make a meet now and invite the external client, the call works.
Am I missing something with the implementation of DNS Load Balancing.
The A Host records on the public DNS have 2 IPs for each record related to Lync Edge Services, example:
access.domain.com 200.10.10.11
200.10.10.12
audiovideo.domain.com 200.10.10.13
200.10.10.14
webconf.domain.com 200.10.10.15
200.10.10.16
Each IP is NAT'd to their respective service in its respective Edge Server. When testing I check that the DNS records are correctly responding from outside.
Any ideas on this particular issue?
Thanks once again!

Hi Edurojma,
The fact that the call rings, and then drops on answering indicates this is most likely an AV routing issue.
You advised that if you create a conference first through meet now, and then invite the participant, that the call works. But this doesn't work peer to peer.
Can I please ask that you check your static routes on your Edge server. The above sounds like the Edge has a route to your Front End server (which would be hosting the conference, hence the success), but doesn't have a route to the subnet that the client
is residing on (hence the failure).
Your Edge server needs to have routes to every subnet that is in use on your internal network.
I might be going down the wrong track, but this is quite a common problem for implementations where specific routes have been defined rather than catch all routes for every possible private subnet.
Check your edge can route to that phones subnet.
Kind regards
Ben

Large Number of Lync Conference Session Failures Every 3 Minutes

I'm wondering if anyone has ever seen this issue before. It's new to me.
A client of mine is experiencing extremely high conferencing session failures in Lync. Once looking into the conferences in question, it looks as though one specific users conferences are in question. A conference session for this users Lync
meetings are attempting to be joined EVERY 3 minutes, 24 Hours a day with a Response Code of 486 and a Diagnostic Code of 34007. Here is a ScreenShot of 10 Minutes worth of these attempts:
This user is not experiencing any problems in joining meetings on his own and he is the only user listed as having unexpected conference failures.
My thought was to restart the AV Conferencing Service or reboot the Front End Servers but wanted to run this past some other first.
Any thoughts?

UPDATE:
It seems as though it was a hung up process with the AVCMU Agent on one of the Front-End servers. A simple reboot over the weekend took care of the problem.
