Skype For Business SE - persistent Chat
Hello, maybe someone of you run into the same error and is able to help me on this topic: we are using SkypeForBusiness only for internal communication last week we have upgraded SkypeForBusinness 2019 to SE: "SkypeServerUpdateInstaller.exe" run without errors, installed the necessary updates and we were able to upgrade to SE on topology builder and publish the new version. on the next step we tried to activate persistent chat. so same procedure for the upgrade: start the update file "PersistentChatUpateInstaller.exe", nothing else to upgrade the first steps (install new sql instance, configure topology builder, publish the new topology were easy, no issues occured. but when we start the Deployment Wizard to install the necessary components we received the error: "File not found trying to install installing c:\programdata\skype for business server\deployment\cache\7.0.2046.0\setup\mgcserver.msi (feature_chat_server)" my question: how can we install the necessary roles/components to activate persistent chat. the file MgcServer.msi couldn't be found on the server, i can't find it on the SkypeForBusinnes 2019 ISO, too. one version i found, was located on the ISO for SkypeForBusiness 2015 ISO, but this version can't be installed. Thanks in advance, best regards, MarkusstimaOct 29, 2025Copper Contributor269Views0likes4CommentsSfB 2019 Install Help
Hey everyone! Happy Monday! I'm trying to install a handful of on-prem Skype for Business 2019 into a lab environment and I'm falling at the second hurdle when running 'Setup or Remove SfB Server Components'. I'm getting the error: 'Error 0x8007054b (The specified domain either does not exist or could not be contacted) setting launch conditions on DCOM layer during action SetDCOMSecurityEx. CustomAction CA_SetDCOMSecurity returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox) Error returned while installing Server.msi(Feature_Server, Feature_HealthAgent), code 1603. Error Message: A fatal error occurred during installation.' All of the servers are part of the same domain. I can log into the skype servers with a domain account, DNs all seems to be working, nltest commands seem to come back normal. Things that I've tried: - Adjusting the COM Security settings for launch and Activation Permission to include RTCUniversalServerAdmins and my admin account to allow local/remote launch, and local/remote activation - Setting a group policy to allow the group EVERYONE to make remote SAM calls (this seemed to have a broken a lot so reverted... I saw it on an MS forum that fixed it for someone) - Run the installer as admin, run it w/out admin - Put the server into a 'staging' area in AD with no policies applied. Fortunately this same error is happening on all servers, which implies that there is a policy, registry key or some permission that's getting in the way. Does anyone have any ideas of some other things that I can try? Thank you! Edit: I know Skype 2019 is old, I know I should be using something else. I'll be moving to Skype SE in Oct.IBrokeitSep 22, 2025Copper Contributor72Views0likes0CommentsHow to Remove Skype for Business
Skype for Business currently installs as a packaged product with Microsoft 365 Business Professional desktop apps. The installation does not install Teams as a part of the Microsoft 365 Business Professional desktop apps. Additionally, Skype for Business has its own installation which is separate from Microsoft 365 Business Professional desktop apps installation. Windows OS: 11 Pro w/ Windows updates. Issues: Users are unable to remove Skype for Business from their desktop by clicking “Uninstall” located on the Windows Start menu. Teams upgrade requires Skype for Business settings to be set manually via the Teams Admin Center. Using the PowerShell command: uninstall-package 'Microsoft Skype for Business MUI (English) 2016' to remove Skype for Business requires NuGet to be manually installed prior to performing a removal task or does not remove the application at all. The odd thing about this is that the system recognizes that a 2016 edition of Skype for Business exists. Note: Microsoft Word reads with the following version number: Microsoft 365 MSO (Version 2508 Build 16.0.19127.20082) 64-bit Granting and then revoking API permissions via Entra Admin center does not separate Skype for Business from the Microsoft 365 Business Professional installation. Uninstalling Microsoft 365 Business Professional desktop apps only removes the Skype for Business app temporarily until reinstallation occurs.sybase54Sep 03, 2025Copper Contributor123Views0likes0CommentsModern Auth with Skype for Business 2015

Hi everyone, I wonder if someone could help me. We‘re using Skype for business OnPrem 2019 and some of our customers complaining about joining meetings. Sometimes it takes several minutes to let you join a meeting. Have you ever experienced something like this delays? We can’t really see anything on the Skype for business server. Could it be related to the hardware itself for example drivers? Thanks in advance.AH2189Mar 22, 2024Copper Contributor286Views0likes0CommentsIssue with Skype Business Pro and Outlook 2016 Status Synchronization
Hello, I have the following problem. Skype Business Pro and Outlook 2016 are installed together. Now, when I have a meeting, I am always shown as online in Outlook to others, and not as busy. In Skype, I have already checked all the boxes. I have also compared with other users, everything is 1:1. What else could I do to resolve this issue?Stranger666Oct 24, 2023Copper Contributor331Views0likes0CommentsWhite screen if use local web client in S4B 2019
I would like that my users don't use MS CDN and use only local S4B web client . 1. I have a link for meeting https://meet.exchlab.ru/test01/5V854YXZ?sl=1 2. If I follow it I see white screen. 3. But this page a not really empty it has a html code. 4. If I set UseLocalWebConfig to $false, web client S4B is downloaded from MS CDN and works perfect, but I need local client, because not all of my internal users have access to Internet. Why I see white screen instead of normal web page?pavelnagaevOct 13, 2023Copper Contributor898Views2likes3CommentsCall made to LyncClient Automation BeginStartConversation, callback not received in certain cases

Sometimes Lync signout- sigin is required to get it working. This issue is observed in a customer environment not in development environment.AlokKulkarniAug 30, 2023Copper Contributor421Views0likes0CommentsSkype for businesss Sign in event received after a lot of delay after restart from sleep/ hibernate
Hello all, Issue with my LyncClient is that I have observed a 2/ 3 minutes delay in getting event for SkypeForBusiness SignedIn after restart from sleep/ hibernate. This issue is not observed on development machine but in customer environment. I read somewhere that these events are received from SFB server and the delay can be because server takes time to sync the events with the client. I am registering for the event using following code during app startup Client.StateChanged += new EventHandler<ClientStateChangedEventArgs>(Client_StateChanged); Any assistance will be helpful.AlokKulkarniAug 30, 2023Copper Contributor406Views0likes0Comments
