I am having some peculiar Issues with Lync .

1, Application sharing – Disconnects automatically almost every 9.30secs. This happens between externally to external users and external to internal users.

2. LWA hangs – Personally through my texts, I have had no issues because I know that chrome no longer supports LWA but I have had a couple of people make the same comments that I am forced to take action to find out why ? When They click on the SKype for Business hypertext it just hangs.

3. Persistent Chat. I just created the persistent chat and while I am on the network, everything is fine but once I disconnect from the network , I get a flash warning “ Your chatroom access may be limited due to an outage” I checked and I have persistchat enabled and have created rooms so why I am having Issues externally but I am fine internally ?

I have run get-cspersistentchatstate ; configuration and endpoint and all are good.

4. Powerpoint Presentation – When performing this of all application sharing internally, I get the error “ some presentation features are unavailable due to some server connectivity Issues” Again of all the application features ( polls, Q& A, whiteboard, desktop sharing, program sharing) only PowerPoint presentation gives the error internally. Externally it works. So externally to Internally , It is fine but internally to externally, It gives the error and when I check OWA server, I see this error message

I've just deployed Skype for Business Server 2015 in my domain but I get the following in my event log persistently.

1) 1e5880b0: ignore error 0x80092013:certificate revocation list offline

2) 1f8da773d0: cert chain trust status is in error: 0x1000040

All my clients work fine, and I've verified my certificate is perfectly valid with a good chain.

I've found a Russian MSDN post with the same problem.

Anyone any ideas?

Hello:

The distributed systems in our org have suddenly stopped getting offline address book updates. I've narrowed it down to Skype for Business, aka Microsoft Lync 2013, locking down the Offline Address book files in:

C:\Users\%username%\AppData\Local\Microsoft\Outlook\Offline Address Books

Thing is, I can't figure out why Lync is doing this or how to make it stop. And it's happening for all distributed systems in our environment.  More details:

Windows 7 64 bit

Outlook 2013 64 bit -- all running in cached mode

Lync 2013 64 bit

Exchange 2010  Version: 14.03.0123.003

The OAB on the Exchange servers is correct and synchronizing correctly across all Exchange servers. As soon as we delete the locally cached OAB -- either by closing Lync and deleting the files, or by deleting the profile and re-creating -- the end-user's GAL looks right as rain.

Rebooting one of the machines and trying to delete the cached OAB gets us the error that the file is in use. Outlook is closed, so it's not Outlook.  We used Process Explorer to see what handle or dll was holding the file locked, and it's Lync.  Since I can't delete the file while Lync is using it, I'm guessing that's also why it can't update. Happy to be wrong about that, but any suggestions or direction are welcome. No one in the systems or support teams is fessing up to making GPO or Lync setting edits in the last month. This issue began on Dec. 8.  There are NO errors in the event logs regarding the Outlook address book not being able to update, however, when you create the profile anew or delete and re-create the OAB manually, you can clearly see the Offline Address Book synch successful message in the event logs.  

Let me know  if I can provide more info.  

Thanks! 

BackEnd Server is running  SQL Mirror.

No idea why front end and backend server broken suddenly. 

Two front end servers front end service stop, SQL server primary can't access normally.

VM Host is Hyper V, Front End and BackEnd is pair on same two host.

Front End BackEnd is on Same virtual network switch with Teaming. The connection should be still on internal and didn't go thought switch.

Lync Event Log:

Event ID: 32134

Failed to connect to back-end database.  Skype for Business Server will continuously attempt to reconnect to the back-end.  While this condition persists, incoming messages will receive error responses.

Sql Mirror Event Log:

Logon,Unknown,Error: 18456<c/> Severity: 14<c/> State: 38.

Any Advise?

Thanks.

Hi,

with the new o2016 you cannot control individual applications in the suite.

Now whenever I click or highlight a telephone number to copy it on a website, it launches skype for business.  This O2016 is on my home machine and not using S4B.

How do I basically just remove S4b.  The threads on stopping it from launchinbg automatically are interesting, but don't answer my question.

Many thanks to the guru's out there.

Hi Team,

We have the Lync forest with the following 3 sites.

Site1 - Lync 2013 Enterprise pool

Site 2 - Lync 2013 Enterprise pool

Site 3 - Lync 2013 Standard pool

I'd like to upgrade Lync 2013 Standard pool on Site 3 from Standard to Enterprise.

Questions:

1. Is there any step-by-step guide or process that we can follow?

2. Will there be any impacts for Site 1 and Site 2 users?

3. Is there any other implications?

Please advise.

Hi folks,

I need help with my environment, it's primarily on Lync 2010, but we were in the early process of migrating to Lync 2013 when we saw Skype for Business 2015 became available. In order to upgrade to **** 2015 I can't have 2010 and 2013 coexisting, and the easiest path is for me to roll back the changes made that introduced Lync 2013 to the environment.

The existing Lync 2013 environment consists of a Standard edition FE server with a Mediation pool, and an Office Web Apps server. The CMS still resides in the Lync 2010 FE server. Any help is appreciated!

Good day!

We use Exchange 2013 Hybrid and had configured Lync 2013 on-premises with Office 365 UM. We used an article by Ioav (here).

Now we try to migrate test user to o365.

Test user is Exchange on-premises UM enabled and granted to hosted voicemail policy on Lync level.

We had set up a license for him in o365.

But in process of migration we got an error:
Mailbox 'testuser' in the source forest is currently enabled for Unified Messaging but it can't be enabled for Unified Messaging in the target forest for the following reason: The UM mailbox policy assigned to the mailbox in the source forest couldn't be mapped to a UM mailbox policy in the target forest. The source forest policy name wasn't found in the SourceForestPolicyNames attribute of any UM mailbox policy in the target forest. Please fix the problem or disable the mailbox for Unified Messaging before you try the operation again

We fixed it and now we have:
on-premises:
Get-UMMailbox testuser | Fl UMMailboxPolicy
UMMailboxPolicy : LyncOnPremDialPlanPolicy

on cloud:
Get-UMMailboxPolicy | Fl SourceForestPolicyNames
SourceForestPolicyNames : {o365UM,LyncOnPremDialPlanPolicy}

where o365UM is a lync hosted voice mail policy which was created in process of Lync configuration.

But the same error still exists!

How should we fix it ? (what/where else setup should be done?)

Thx.

Hi All, 

I'm currently trying to upgrade my LHP 2013 to latest update. 

Current updates are as below. Lync 2013 Front End (LHPv2)

Core Components: 5.0.8308.315
Web Conferencing Server: 5.0.8308.291
Conferencing Server: 5.0.8308.291
Lync Frontend Server 2013:5.0.8308.304
Web Components Server: 5.0.8308.315

Below article says it is the same update for both LHP and Lync Server 2013 

https://www.microsoft.com/en-us/download/details.aspx?id=36820 

Please confirm, so that i can proceed with the patching. 

I keep getting this below alert from our Front end servers.  We have CU5 installed on those. 

We have 2 Lync 2013 pools however alerts pops up on one of the pool and interesting fact is that alerts are triggered mostly off peak hours.  I don't see any impact however would want a solution for this alert.

I know that Lync/Skype do not support dynamic VHDX disks. I am holding true to all the virtualization requirements, yet the team that is building out my SQL back end servers, say they plan to use dynamic VHDX disks.

Is this supported?

The entire Skype infrastructure is being virtualized, though I know that the SQL backend servers can be physical or virtual, regardless of how Skype is setup. But can the SQL disks for Temp, Database, & Logs be dynamic? My concern is performance.

Thanks,

Christian

The certificate on both Edge servers on the external interface was expired. On the first Edge server I have done all the steps to request and install an new certificate. This worked without any problems. I have exported the certificate to a pfx file. Now I want to import the certificate on the second Edge server. When I want to import the certificate in the Deployment wizard, I get an error:
Missing an argument for parameter Password. Specify a parameter of type system string and try again.

The pfx file has the private key.

Hi guys.

Long story short.

Two lync 2013 STD frontend servers.

LyncPRIMARY.domain.local
LyncSECONDARY.domain.local

Lync resilency was configured and enabled "a long time ago". We have figured it out that LyncSECONDARY was not connected to NIC "a long time", so we have fixed that and pushed syncing between them.

Now the question:

If we take a look this SITE: http://blogs.technet.com/b/jenstr/archive/2012/11/06/what-does-the-status-reported-by-get-csbackupservicestatus-mean.aspx

There are status of backupservice explained. Now we would like to figure it out which of our Lync servers has active CMS.
Active CMS means that this server is "primary one" true?

Is it possible that we have wrong confiugrated lync resilency because output of Get-CsBackupServiceStatus is:

Get-CSBackupServiceStatus -PoolFQDN lyncprimary.domain.local

ActiveMachineFqdn                             OverallExportStatus              OverallImportStatus BackupModules
-----------------                             -------------------              ------------------- -------------

ActiveMachineFqdn   OverallExportStatus OverallImportStatus BackupModules
-----------------   ------------------- ------------------- -------------

If I take a look on that site (under comments): http://blogs.technet.com/b/jenstr/archive/2012/11/06/what-does-the-status-reported-by-get-csbackupservicestatus-mean.aspx

Jens>For the pool with the active CMS the ExportStatus will be FinalStateand ImportStatus will be NotInitialized. For the passive CMS the ExportStatus will be NotInitialized and the ImportStatus will be NormalState.

So is it possible that in our case Lync2013SECONDARY is the "primary" because the status is FINALSTATE and that means it has ACTIVE CMS? That is not a desired behavour...

Hi All, I have a Lync 2013 Standard Edition Front End (newly installed) and the Front End service returns an error (1067) when i attempt to start it. I have seen plenty of posts with the above related issue and have checked: DNS entries, CU Updates, Reset Pool registrar and Quorum, unfortunately to no avail. In looking at the event viewer i keep getting the following:

OWA Farm is configured on two 2012 servers. Lync 2013 installed on server 2012 as well.

I can access all services, internally and externally without issues on the client end.

However, my OWA farm machines are marked as Unhealthy per get-OfficeWebAppMachines.

The OWA Farm system Logs show multiple events related to source Office Web Apps Monitoring, event ID(s) 1004, 1010, 2004, & 2010.

What are the BroadcastServicesWatchdog_Wfe & AgentManagerWatchdog that are running, reporting these event codes, and where can it be managed?

The actual event codes

Hi All-

I hope this finds the right set of eyes as I am looking for some insight on a minor event that occurred today, that I am trying to just get a better understanding of what happen.

Virtualized Lync 2013 enterprise environment, Multiple Front End Servers
VMWare 5.5, Shared Storage, no RDMs

This morning we have a top of rack switch reboot (bug in code) and I quickly logged in to notice we lost one uplink on all of our applicable hosts.  Not a big deal, fully redundant, active/active ports backing the port group the Lync servers are connected to.  About 90 seconds later connection was restored and no VMs felt a thing, at least I thought.  At the very most those VMs would have dropped one single packet.  Our SCOM alerts started to churn and we had users with some disconnected Lync sessions on that office/datacenter.  Some alerts were below, granted only the Lync environment barked, not another application felt it.

Connection attempt to at least one service in a pool failed.
Connection attempts to the following services have failed. Another attempt will be made for each service every 10 minutes.

Conferencing Announcement Service lost connection with the Microsoft Lync Server 2013 Front End.
Cause: This issue may occur due to network connectivity, DNS lookup failure, TCP failure or issues on the remote server.
Resolution:
Resolve network connectivity issues between Conferencing Announcement Service and the Microsoft Lync Server 2013 Front End.

Local Pool Manager has been disconnected from Pool Fabric Manager.

Cause: This may happen if many Front-Ends in the cluster have gone down or become unreachable, causing loss of quorum.

Resolution:

Ensure that a majority of the Front-Ends configured for this pool are up and running. If multiple Front-Ends have been recently decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.

We looked at our Lync environment shortly after and it appears to heal on its own, good news.  My question is would a shot network blip cause the application to exert the above behavior.  Note all virtual hosts felt this, so every VM would have had at worst case, one dropped packet.  Can anyone chime in on how Lync would feel that, I know its a rare scenario and have read the guide on deployment, but just trying to determine why that occurred.  Thank you for any insight.

Hello All,

Greetings,

Recently we have received a request from our management to implement xmpp with google for the im.

We went through a couple of blogs and the way to implement but couldn't find something with confidence, Could you please help us with some of them

Also few of them also state that google has now stopped accepting such requests from lync and that we dont really have the confirmation that even if implemented it would work.

Could please help us find answers to these question.

Thank You!!! BR, Ammi.
