Current State:
1 Forest/1 Domain
AD Connect to Office 365 (syncing password hashes)
All on-premises Lync and Exchange servers have been decommissioned in the environment

Most users have attributes like this populated - looks like this from old on-premises (However, many are synced to 365):
msRTCSIP-DeploymentLocator
msRTCSIP-FederationEnabled
msRTCSIP-InternetAccessEnabled
msRTCSIP-OptionFlags
msRTCSIP-PrimaryHomeServer
msRTCSIP-PrimaryUserAddress
msRTCSIP-UserEnabled
msExchShadowProxyAddresses

Q: Can I clear the above attributes without issue?

The reason I ask is I would like to clear the above attributes when I implement the following changes (which is the actual project at hand):

UserPrincipalName attribute    
from foo@contoso.com to foo@fabrikam.com

Mail attribute    
from foo@contoso.com to foo@fabrikam.com

ProxyAddresses attribute - the PrimarySMTPAddress
from SMTP:foo@contoso.com to SMTP:foo@fabrikam.com

ProxyAddresses attribute - the old PrimarySMTPAddress will become the secondary
from SMTP:foo@contoso.com to smtp:foo@contoso.com

ProxyAddresses attribute - the SIP Address
from SIP:foo@contoso.com to SIP:foo@fabrikam.com

Hello Experts

Somebody can tell me what rules should my TMG server have to allow SIP from outside

i am working on a hybrid project Lync 2013 to Office 365 and i am not an expert of TMG but the person who did the configuration before did a Publish rule to allow port 443 for Lync but i suspect i have to add port 5061 because my cloud users are not able to see presence info of On prem users but Onprem users can see the Presence Info and send messages

Please i need help

Dear All,

We are running Microsoft Lync Server 2013 Hosting Pack with the latest Cumulative Update KB 2809243 (version 8308.992), published in July 2017.

Currently, and since February 2018, all our customers are facing an issue with the mobile client for iOS  (https://itunes.apple.com/us/app/skype-for-business/id605841731?mt=8) and more specifically with push notifications.

Incoming calls are not pushed to the mobile client anymore, even with the “Background App Refresh” option enabled.

Back in November 2017, with the App version 6.17.3, push notifications were still working correctly, but the version 6.18.1.x deployed in February 2018 broke the service.

I still have an iPhone 7 with App version 6.17.3 (Nov 15, 2017) where push notifications are working perfectly.

I'm sure our infrastructure is OK, and the proof is that with an older App version, everything works well.

Do you have any suggestions?

Thank you a lot

We are just starting to use Skype For Business for Internal IM.   We have setup Skype For Business to not allow External Contacts to be added. We didn't want Employees to start chatting with Friends and Family while at work.

We are looking to get rid off WebEx for Presentations and wanted to use Skype For Business, though it looks like we can't Invite Customers to the Meetings since we blocked External Access.

Is there a Way to Block External Users for IM, though Allow Inviting External Customers for Presentations?

Thanks!

We are setting up Skype for Business 2015.
In the boardroom I have setup a Laptop with Windows 10 Pro and Skype for Business to be used for Video Conferencing. I have attached a Logitech BCC950 Conference Cam to the laptop. When looking at the Preview in Video settings, you can get a stream from the camera. Once you connect a video call you get the message "Could not start Video: Your camera is not setup or you are already using it."
There are no other applications that could be using the Camera.

I have tried the following:
  1. Updated the driver to the latest that Windows updates can find as Logitech does not supply updates on their website.
  2. Installed all Windows updates.
  3. Changed USB ports. These are only USB 2.0 ports.
  4. Tried a different computer with the same setup but have the same issues.

Can anyone help?

Thanks in advance.

lync 2010 response group not showing workflow name on incoming calls.
when i create a new workflow as a test that works out fine, but i am thinking perhaps there is cache of names that the machine or lync server holds on to that i can flush. or perhaps i am misdiagnosing the issue somewhere.
What I am seeing now is that the interactive response group is what is not showing the sub response is not translating to the option selected which would take you to the hunt group; which then needs to show the option selected option to the users client
i would appreciate the assistance

Hello all, we are migrating from Lync 2010 on prem to Skype for Business in O365. Part of this move will be a transition to Webex for folks who have PTSN conference creation rights. Rather than move everyone to Webex with those rights, were looking to move only those that have created conferences within a defined time period.

Question is, how do i pull a report to show the number of PTSN conferences created per user, over a 12 month period?

thanks in advance.

How is a two server Edge pool in Skype for Business 2015 server on premise load balanced?  
If I just have one server in the pool it works just fine.  As soon as the second server is added, no one can connect.
We have the external NICs load balanced and NAT'ed so that we only have to use 3 public IP's instead of 6 or 7.

Hi all,
 
I Have a Skype for Business on prem install with a single Front end server and Edge server. Afte rinstalling I have since enabled federation so that my SKype users can add users from other domains.

I downloaded the current topology, made the relevent chages then republished.

However, its my understanding I have to rerun the installion on Front End and Edge server in order for the topology to be loaded?

Can anyone offer assistance with this?

Hi

I've been wrapping my head around this for quite some time - still accomplishing nothing but headache. Here's the setup

Lync 2013 mediation server
Lync PSTN Trunk points to Avaya Aura RED
Avaya Aura RED routes PSTN traffic to Avaya phone central

We have landline numbers in Lync, and cell phone number with a PSTN provider

Lync <-> avaya RED gateway <-> Avaya phone system

Also - we've setup so that calls to cell phone in PSTN, will also simultaneous call Lync number.

so;
1. user call my cell phone (tel: 99 99 99) from his IP-phone/cell phone
2. this will call on my cell phone, but will also trigger a call to landline on lync (tel: 22 22 22). Since we've  set this up with PSTN provider
3. this will also make Lync call (at 22 22 22)
4. so the user called cell phone at 99 99 99 and both cell phone will ring, together with Lync client.
5. if I answer the call with either cell phone or lync - the ringing will stop on the other device

so far so good.

But if this process is repeated, but this time the call is initiated from a Lync client at the internal office

1. user call my cell phone (tel: 99 99 99) from enterprise voice enabled lync client
2. this will call on my cell phone, but will also trigger a call to landline on lync (tel: 22 22 22). Since we've  set this up with PSTN provider
3. this will also make Lync call (at 22 22 22)
4. so the user called cell phone at 99 99 99 and both cell phone will ring, together with Lync client.
5. if I …

We have implemented Skype for Business 2015 PSTN conferencing without Enterprise Voice.

We do not use address book normalization because we have call centers that do not want unique phone numbers or extensions listed in their contact cards and all of them having the same phone number causes a mix up of user information among those users.

Users enter the phone number they want the conference to use when they choose the "Call me at" feature when joining conferences in the client phone options Work field.

This number is being cleared randomly.

Has any one seen this before?  If so what was the resolution?

Hello Experts,

My company currently has an on-premise deployment of Lync 2013 with most if not all features functioning and integrated with our Avaya PBX. To provide further detail, we can do web based and audio conferencing, mobile apps works, and from our S4B desktop clients we can 4-digit dial extensions and make and receive calls to the world etc. as well as from our mobile apps. Edge servers, reverse proxy, all required components are in place.

I recently completed a hybrid migration of Exchange 2010 to O365 successfully, all users are on O365 (E3) but we still use on-premise for relay and management. Azure AD Sync is setup for password sync, we do not use ADFS.

I want to do the same with Lync 2013, setup hybrid and move users over little by little until we are comfortable and keep all the functions of S4B with our on-premise PBX. From what i read i will need to add a cloud pbx license for this to work but cannot find any "Good" information on setting up Hybrid and how to keep those features. Does anyone know of any good resources that covers this scenario in DETAIL?

Whats paths are there? Is there more than one? Some direction will be greatly appreciated.

Hi All,
I recently took over a Lync 2010 setup that had a self-signed certificate. I've been asked to set up federation with outlook.com and enable mobile access. The first thing to do was get a proper certificate, which I did from GoDaddy. That cert has been applied and when testing both internally and externally using the ruct.exe tool from http://blog.insidelync.com/2011/11/the-remote-uc-troubleshooting-tool-ruct/ the correct certificate is being pulled down, Lync on desktops internally and on laptops from home all continue to work away as normal.

The problem is I cannot get federation or mobile access to work. I've enabled federation, have port 5061 open in and out to the edge server, Gone through the federation with Microsoft etc.

I think the issue is still down to the certificate though. When I test the certificate using DigiCert or SSL shopper neither can connect. both say the connection failed so the SSL cert check fails too.  I am able to telnet to my edge's address (DNS and IP) on ports 5061 and 443 and the RUCT tool is able to connect without issues.

Any idea what could be causing the digicert and ssl shopper certificate checkers to fail to connect? I can only assume a cert problem is causing my federation and mobile woes. I've nothing else to go on

Thanks

Lync IVR
I tried to create the IVR using powershell. Below cmdlet:

How Can i resolve this issue?

The client is using Lync in conjunction with Cisco UCM and complains about occasional voice quality issues.
Normally with Cisco phones and CUCM you let the phones use the voice VLAN and tag the traffic that comes
onto the voice VLAN. But with Lync - that traffic is just traveling with all the other data traffic. What's the best
way to tag that traffic as real time EF as near the source as possible?

We have a working S4B setup and are trying to add Director role.
We deploy new Director VM, add it to S4B topology, deploy necessary certs.
We change DNS to point lyncdiscover to Director, redirect TCP/443 to Director instead of FE (same port 4443).
But authentication does not go through.

Any clue how to troubleshoot?
