Understanding: Lync client Configuration Information

Standard

We use many tools to troubleshoot Lync.

the “Lync Configuration Information” option on the Lync client actually provides a lot of useful information about how the client connects to the server and can help identifying issues.

To access the Lync client’s configuration information, go to your computer’s Notification area and look for the Lync icon:

Notification AreaHit Ctrl and right-click the Lync icon, then choose “Configuration information”:

Lync Configuration InformationA new window will open up, showing you your client’s configuration:

Configuration Window

This Windows will provide you with all the information your client is retrieving from the server and from your settings.
You can copy the contents of this windows to a text editor by clicking “Copy”, or close it by hitting “Close”.
“Refresh”, however, will surprise you and do nothing. If you want to refresh the information displayed in this window you’ll have to close and reopen it…

Let’s cover this Windows’s contents line by line. Note you might not have all the information populated. This might depend on your actual implementation or connection state:

 

DG URL Internal Lync Server 2013 will populate the Lync address book with all the Distribution Groups it finds in your Environment. If in the organization’s network, your client will use this URL to connect to the server and expand these groups to show theirs members. This should normally point to the address of your Front-end pool or server.
DG URL External Same as DG URL Internal, only for external users. Your client will use this URL to connect to the server and expand these groups to show their members when you’re connected to Lync from outside of your organization’s network. This should normally point to the address of your Reverse-Proxy server, representing Lync’s External base URL.
Quality Metrics URI This should represent the address of the Front-end server you’re connected to. The Front-end server will in turn use the MSMQ feature to send your quality metrics to the Monitoring Server. If this field is populated, it means you have monitoring enabled for the pool you’re connected to.
ABS Server Internal URL If configured to download the Lync address book via web service, your client will use this url when connected inside the oraniztion’s network.
ABS Server External URL Your client will use this url to download the Lync address book when connected outsidde of the oraniztion’s network.
Voice mail URI This string shows how other clients and services are calling your voicemail.
Exum URL This field represents how calls are routed to your mailbox. It would normally show a familiar dial plan’s name or just say “destination=default”. Having this fileld populated usually means you’re enabled for Voice mail.
MRAS Server MRAS stands for “Media Relay Authetication Service”. This service provides your credentials to the AV Edge Server. when this field is populated, it means you successfuly authenicted against the AV Edge server.
GAL Status This field shows which server was used to download the address book and if it was successful.
Focus Factory The “Focus Factory” is where all your conferences are created. The server will use the URI listed in this field when you create a new conference or Lync Meeting.
Line This shows your line URI.
Line Configured From “Line configured from” shows where the line was configured. In this case, the line was configured on the server.
Location Profile This setting is actually pulled from your Exchange server, and represents the location profile of your Exchnage UM Dial plan.
Call Park Server URI If you enabled Call Parking for this environment, your call park server URI will be displayed here.
Server Address Internal If you configured your Lync client to use a manually entered internal address (see This post), the configuration will be displayed here. Note that even if you switched to automatic configuration but haven’t cleared the names, it will still be displayed here.
Server Address External Same as Server Address Internal, but for external access addresses.
Server SIP URI Denotes the SIP uri that’s signed against the server.
Exum Enabled will say “TRUE” if you’re enabled for Exchange UM or “FALSE” if, well, you’re not.
Controlled Phones This will display your phone’s model if you have a Tanjay-compatible device connected.
GAL or Server Based Search Depending on your Client Policy Configuration, this will display whether you’re retrieving the adress book using the web service or the Lync Shared Folder.
PC to PC AV Encryption Should usually say “AV Encryption Enforced” unless you changed it to “DoNotSupportEncryption” or “RequireEncryption” on your Media Configuration settings.
Telephony Mode This will display either “Telephony Mode UC Enabled” if you’re Entreprise Voice enabled, “Telephony Mode Disabled” if you’re set to PC-to-PC only, “Telephony Mode No Audio” If you have Audio/Video disabled, “Telephony Mode RCC Enabled” if you have RCC turned on, or “Telephony Mode RCC Only” if you enabled RCC only for this user.
Line Configured From I have only seen this one set as “Auto Line Configuration”.
Configuration Mode “Auto Configuration” means you’re set to automatically find and connect tho the server. “Manual Configuration” means you’re using the values provided in “Server Address Internal” and “Server Address External” to connect to the server.
EWS Internal URL This should point to the internal url of your EWS virtual directory, i.e. your internal Exchange CAS or CAS Array. If this setting is misconfigured (automatically retrived from Exchange), you might not be able to access Outlook free-busy from you Lync client and Lync phone.
EWS External URL Points to the address of your external EWS virtual directory, based on the settings of your organizations’ Exchange Autodiscover configuration. If you’re using Office 365 Exchange Online, you will see only this field populated, pointing to https://outlook.office365.com/EWS/Exchange.asmx/WSSecurity.
SharePoint Search Center URL points to your organization’s SharePoint Search Center URL if you configured Lync-SharePoint integration.
Skill Search URL points to your organization’s SharePoint Skill Search URL if you configured Lync-SharePoint integration.
Connected Lync Server Shows which server you’re connected to at the moment.
Local Log Folder Shows the location of the Lync logging folder. This usually points to %userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\Tracing.
Inside User Status If set to “TRUE” – the user is connected directly to a Front-End server or a director. If set to “FALSE” – the user is connected to the organization via the Edge server.
Contact List Provider Will display “Lync Server” if Lync is providing the contacts list, or “UCS” if Exchange Unified Contact Store provides it.
Pairing State Will determine wehther Pairing is enabled or not, and will display the phone’s model if paired.
UCS Connectivity State Will display “Exchange connection Down” if UCS is not your Contact List Provider or if Lync can’t make a connection to the UCS.
MAPI Information “MAPI OK” means Lync was able to communicate with Exchange via Outlook. “UCMAPI is connected to Outlook, but one or more folders are not updating.;MAPI unavailable” means either the Lync user and the Outlook profile don’t match, or Outlook is closed.
EWS Information “EWS Status OK” means Lync was able to contact Exchange through EWS, “EWS has not fully initialized” means it’s in the process of Autodiscovering EWS, “EWS not deployed” meand Lync was not able to communicate with Exchange via EWS.
License State Shows if Lync is licensed and what sort of licesnse is assigned.
Hanging Notification Status This will either appear as “Connected” or “Disconnected”, any input on this field is appreciated!
pChat Room Mgmt Int URL Denotes the internal url for Persistent Chat Room Management
pChat Room Mgmt Ext URL Denotes the external url for Persistent Chat Room Management
pChat URIs Will display all Persistent Chat URIs
pChat Default URI Will display the defualt Persistent Chat URI
pChat Enabled? “True” means you’re Persistent Chat enabled and the above filelds shoud be populated. “False” means you were not enabled for Persistent Chat, and the above fields shoud be blank.

    According to my experience, since the 2007 R2 days, the refresh button does not work at all! Or at least it does not what the averae Lync IT pro should expect: to refresh the contents of the values since the window has been opened. As the interpretation of this windows is completely undocumented, nobody really knows what the refresh button would do, if it does something different than I explained above.

    For some reason, MS seems unable to fix this stupid artifact. Or if they are unable to fix this, even better if they just remove that damn button, so the person doing troubleshooting does not have any expectations that the damn button should actually DO SOMETHING.

  2. Do you known exactly how the lync Client get’s this info?
    I have a customer that has some users where the ‘Server SIP URI’ is missing, and the ‘Connected Lync Server’ Show the pool FQDN instead of the Server.
