In this post I just like to quickly highlight where you can find the latest Microsoft Skype for Business Server updates. Recently Skype for Business Server 2015 May 2020 Cumulative Update (CU) was released. However, the update was only downloadable from the EN-US download page, not from the DE one. On the DE download page for SFB Server 2015 only the August 2019 CU was available. I guess it will just take some time until it is refreshed and also available on the DE download page.
In general you can find the most recent CUs on a Microsoft Docs summary page where you can
- get an update history incl. release date of the update
- find the link to the respective knowledge base article which provides an overview on the included changes of the according update (release notes)
On the latter, the KB page you can open further links to each mentioned change or fix which the update delivers. There you can read through a more detailed explanation and update description.
First of all, you should read the update’s KB article. Afterwards you can download the package but please do not just download and install the update. To install the update should be a planned task. It might require some preparation and cause a downtime depending on your actual SFB deployment. And don’t forget the update the backend. I’ve often noticed that the backend is not updated although the description of the CU states how this has to be done depending on the SFB deployment (Standardard Edition vs. Enterprise Edition).
