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, Markus
How 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.
Issue 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?
Skype Web Components Server Error
Good day all, Been having a strange issue regarding TLS and Web Components Server Errors since deploying a new single server. There is currently 2 single servers on the topology and moving a user from one FE server to the other seems to not always work, especially if they are coming via the EDGE server. On most login requests we receive the below errors in the even logs: { An unhandled exception was encountered. Service: WebTicketService, exception details: System.ComponentModel.Win32Exception (0x80004005): The client and server cannot communicate, because they do not possess a common algorithm at System.Net.SSPIWrapper.AcquireCredentialsHandle(SSPIInterface SecModule, String package, CredentialUse intent, SecureCredential scc) at System.Net.Security.SecureChannel.AcquireCredentialsHandle(CredentialUse credUsage, SecureCredential& secureCredential) at System.Net.Security.SecureChannel.AcquireClientCredentials(Byte[]& thumbPrint) at System.Net.Security.SecureChannel.GenerateToken(Byte[] input, Int32 offset, Int32 count, Byte[]& output) at System.Net.Security.SecureChannel.NextMessage(Byte[] incoming, Int32 offset, Int32 count) at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.Security.SslStream.AuthenticateAsClient(String targetHost) at Microsoft.Rtc.Internal.WebServicesAuthFramework.RemoteCertificateResolver.ResolveCertificate(HostAddress hostAddress, Int32 port, ICollection`1 allowedNameList) at Microsoft.Rtc.Internal.WebServicesAuthFramework.WebTicketRemoteSecurityTokenStore.ResolveAndCache(String key, HostAddress hostName, Int32 port, ICollection`1 allowedNameList) at Microsoft.Rtc.Internal.WebServicesAuthFramework.WebTicketRemoteSecurityTokenStore.GetSigningTokenByIssuer(HostAddress hostAddress, Int32 port, ICollection`1 allowedNameList) at Microsoft.Rtc.Internal.WebServicesAuthFramework.WebTicketRemoteSecurityTokenStore.EnsureIssuerSecurityToken(HostAddress machineAddress, Int32 port, ICollection`1 allowedNameList) at Microsoft.Rtc.Internal.WebServicesAuthFramework.WebTicketKeyStore.EnsureIssuerSecurityToken(Uri issuerUri) at Microsoft.Rtc.Internal.WebTicketService.WebTicketService.BeginIssueToken(Message rstMessage, AsyncCallback callback, Object state) at AsyncInvokeBeginBeginIssueToken(Object , Object[] , AsyncCallback , Object ) at System.ServiceModel.Dispatcher.AsyncMethodInvoker.InvokeBegin(Object instance, Object[] inputs, AsyncCallback callback, Object state) at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11(MessageRpc& rpc) at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet). Cause: Application error. Please look through the exception details for more information. Resolution: Restart the server. If the problem persists contact product support.} Restart obviously didnt resolve this issue. Checking the system logs, I see the following schannel errors: A fatal error occurred while creating a TLS client credential. The internal error state is 10013. When I checked the TLS settings on the FE (which is where I get all these errors above) with inetcpl.cpl I see that only TLS 1.2 is ticket. Looking at the EDGE server, there is no apparent error that is causing this. We just added the new servers to the SRV and A Record DNS entries, so this shouldnt be an issue. The EDGE has the below schannel errors: An TLS 1.2 connection request was received from a remote client application, but none of the cipher suites supported by the client application are supported by the server. The TLS connection request has failed. Not sure if this could cause any issues though as the working environment has the same errors as the above.External Edge Certificate - Unable to remove auto injected local FQDN SANs when renewing certificate
Hi, I am trying to renew our external Edge certificate but find I am unable to complete the process as during the renewal in the Deployment Wizard I am warned that "FQDNs in your request may contain reserved or special top level domains, and are likely to be rejected if the request is submitted to a public Certificate Authority". I can see two local domain names which are automatically added as Subject Alternative Names during the renewal wizard and I am unable to remove them. I would appreciate any help with resolving this if possible. Regards NigelSchedule a webinar using Skype for Business 2016

Skype to Teams Transition "Try it" URL
So, I'm in one of the sovereign MS365 cloud instances and we are transitioning from Skype for Business online to Teams. in the Teams Upgrade window there is a "Notify Skype for Business users that an upgrade to Teams is available" switch. When it is turned on, Skype displays a blue banner at the top with a "Try it" button. With the "Download the Teams all in the background for Skype for Business users" switch turned on, if a user clicks the "Try it" button before the client install has been downloaded to their machine, it will launch a browser and send the user to the public teams site (teams.microsoft.com). This will cause an error when the user tries to login. Is there any registry or file that can be changed to cause the 'Try it" button to redirect the user to the appropriate sovereign cloud's URL?MFA issue when moving users
H All. I'm having a real issue with MFA when it comes to moving a clients users from On-Premise to Online. The admin account i am using is MFA enabled and this cannot be disabled. I am getting really frustrated with having to authorize the login for the account every time ( or so it seems ) a user is moved. I am using a csv file so importing and then running the Move-csuser command in powershell. Is there a single command to stop this from happening or to force O365 to accept the fist time authorization...
