Skype For Business SE - persistent Chat

Okay! Fixed this one.

To keep it short: Microsoft recently released the SE ISO, before you worry, you do not need it in the way you first think... you can keep all your servers, no reinstallation!

I was able to resolve it by logging on to the server (in my case, a Front-End Standard Server), mounting the ISO via SCVMM, and opening it in File Explorer. From there, I copied mgcserver.msi to the following path:

C:\ProgramData\Microsoft\Skype for Business Server\Deployment\<Version>\setup\

After that, I re-ran the Deployment Wizard, which completed successfully.

At the moment, I am updating the component using PersistentChatUpdateInstaller. Once that is finished, I will run Start-CSWindowsService and verify whether Group Chats can be configured successfully again.

One important note: after publishing your topology, do not turn off the services immediately. The topology needs time to properly register the new server before it can be used. Otherwise, a rollback of the changes may be required.

Have a nice day and greetings from germany "habibi!",
