How to rollback unified contact store (UCS) contacts from Exchange to Lync?


How to rollback unified contact store (UCS) contacts from Exchange to Lync? 

In short disable UCS and move Lync contacts from Exchange mailbox to Lync.
Recently one of my client requested to disable Unified contact store and migrate Lync Contact from Exchange 2013 to Lync Server 2013. 

To roll back Contact Storage from UCS to the Lync Pool, it is a straight forward two-step process: 

Disable UCS policy and then roll back contacts.
1.   First disable UCS in the Policy the users are associated with to prevent us migrating back: 

Set-CsUserServicesPolicy -Identity "" -UcsAllowed $False

If you want to roll back contact from UCS to Lync pool for all users then use policy name as “Global”. 

2.    Use below command to disable unified contact store for the individual user.  

Set-CsUserServicesPolicy -Identity "UCS Enabled Users" -UcsAllowed $False 

3.    You can rollback the specific user using below command. 

Invoke-CsUcsRollback -Identity "" 

Example:  

Invoke-CsUcsRollback -Identity "Balu Ilag"

Unable to see Lync contacts on iOS and Android.


Issue: Unable to see Lync contacts on iOS and Android.
Error: No specific error, just shows Lync contact blank on mobile devices.

Problem Statement:
Using UCS (Unified Contact Store) however recently Lync contacts stopped displaying on iOS, Android, Windows App etc.
Lync contacts shows on Windows Lync 2013 client, Skype for Business client however not showing on mobile devices, iPad etc.
EWS (Exchange web services) is working fine on iOS, android, windows app device as calendar information shows correctly.
Resolution:
You can follow below steps in order to troubleshoot this issue.
Note: In order to test below all mentioned commands you may need CsAdministrator and RTCUniversalServerAdmins group permission.
1.    Browse EWS URL (external) from mobile device and see the result. If EWS is not working then work with Exchange admin and correct EWS issue.
In my case EWS URL was browsing correctly. EWS response looks like the below image.
 

2.    Lync contact not showing on only mobility devices hence check the below:
A.    Check Lync iPhone log. I was seeing “Get” request from client for Contacts and Group and seeing “Post” response from server however contact not display on Lync client on mobile device.
B.    IIS log shows 404 errors hence did IIS reset on all Front End Server.
a.     IISREST.
b.    Repair IIS URL rewrite module (Select IIS URL rewrite module and right click it, you will see repair option, > Select Repair on Frontend servers.
c.     Still issue persist. 

3.    Later Tested UCS, so there no Authentication error however test failed. See below.
PS C:\> Test-CsUnifiedContactStore -UserSipAddress bilag@mydomain.com 

-TargetFqdn "Lyncpool1.mydomain.com" -UserCredential $cred Target Fqdn   : lyncpool1.mydomain.com
Result        : Failure
Latency       : 00:00:03.3708299

Error Message : Contacts notification was not received within 50 seconds.

4.    Now test exchange connectivity:
Test-CsExStorageConnectivity -SipUri Bilag@mydomain.com 

PS C:\> Test-CsExStorageConnectivity -SipUri "sip:bilag@mydomain.com"
Test-CsExStorageConnectivity : ExCreateItem exchange operation failed,

code=574, reason=StoreContext{traceId=[1687025949],

activityId=[3936b2b9-e0bb-4b05-b0e7-bdf8d9a6eca1]}StoreException:

code=ErrorUnhandledException, reason=Wrapped callback failed --->

System.Web.Services.Protocols.SoapException: The application is missing a

linked account for RBAC roles, or the linked account has no RBAC role

assignments, or the calling users account is logon disabled.
 
 
Tried to invoke UCS rollback command however it give below error.
Invoke-CsUcsRollback –Identity “sip:bilag@mydomain.com
 
 
 
It shows application is missing a liked account for RBAC role. But there is no clear documentation on what RBAC role is missing.
 
Issue does look like a more general OAuth issue that is causing both the Test (CsExchangeConnectivity and CsUnifiedContactStore) and UCS rollback to fails. Looks like partner applications have a related account that may have some issue. 

5.    Now check partner application. Log on to exchange Server and Open Exchange Management Shell and check partner application.

PS C:\> Get-PartnerApplication 
Result:
AuthMetadataUrl: https://lyncpool.mydomain.com/metadata/json/1
Realm  : mydomain.com
UseAuthServer : False
AcceptSecurityIdentifierInformation : True
LinkedAccount : mydomain.com/Deleted Objects/LyncEnterprise-ApplicationAccount 

So issue is partner application liked account is deleted or not available. 

6.    In order to resolve this, we have two options:
a.     Restored deleted liked account.
b.    Setup / configure partner application again to get linked account create.
In my case linked account is not showing under recycle bin in Active Directory hence configuring partner application again to created partner application is best option.
Follow below steps to create partner application linked:
1.    Login to Exchange 2013, Open Exchange Management Shell.
2.    Go to path C:\Program Files\Microsoft\Exchange Server\V15\Scripts>
3.    Run below command:

C:\Program Files\Microsoft\Exchange Server\V15\Scripts>Configure-EnterprisePartnerApplication.ps1 -AuthMetaDataUrl 'https://Intwebsrv.mydomain.com.com/metadata/json/1' -ApplicationType “Lync"
 

4.    Run IIsreset from Exchange management shell agents all Exchange 2013 server name.
7.    Now time to check partner application and validate the same..
Run command:
Get-PartnerApplication 
And see the linked account and verify 

LinkedAccount : mydomain.com/Resources account/LyncEnterprise-ApplicationAccount 

8.    Then test Test-CsExStorageConnectivity -SipUri "sip:bilag@mydomain.com"
 Test passed. J
 

9.    Time to log on to Lync 2013 client on iOS, Android and Windows device and see the Lync contacts.

In my case contacts show correctly.

 

Thank you.

How to control Skype for Business UI using registry key?


How to control Skype for Business UI using registry key?

Whosever install latest Microsoft Office 365 ProPlus and Office 2013 Pro. Updates or repair Office 2013 and 365 using online repair option then they will get Skype for Business 2015 client as replacement of Lync 2013 client.
I have many customer who are on Lync Server 2010 and 2013 with old CU because of that they are unable to control “EnableSkypeUI” flag using PowerShell from Server.
For user who are on Lync Server 2010 and 2013 with older CU than December 2014 they will asked to switch to Lync mode.
Using registry you can manage ‘EnableSkypeUI’ flag.
1.    Enable Skype for Business UI using registry:
NOTE: You must have latest Office 365 ProPlus or Office 2013 updates installed on your computer.
a.     Open Registry, Start > Run > regedit
b.    Browse below registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\Lync

c.     Right click on key and select Modify:
Value data: 01 00 00 00 00
 
d.    Click on OK.
e.     Restart Lync client to back to Skype for Business.
 
Every time you restart client you need to change registry key value to 01 00 00 00 00. 

2.    Disable Skype for Business UI using restart:
a.     Open Registry, Start > Run > regedit
b.    Browse below registry key:

HKEY_CURRENT_USER\Software\Microsoft\Office\Lync

c.     Right click on key and select Modify:
Value data: 00 00 00 00 00
 

 
d.    Click on OK.
e.     Restart Lync client to back to Skype for Business. 

Once Skype UI disable it will stay as disable.  

PA: Skype for Business name under Office 2013 will stay and Icon will not get change to Lync it will stay as Skype for Business Icon. 

You can control these registry key using GPO. 

Thank you.
