SfB 2019 Server Update – June 2023

It’s been a while since we’ve seen an update to Skype for Business Server 2019, October’s 7.0.2046.409.

Today we see build 7.0.2046.521, which updated six components on my Standard Edition Front-End.

What’s New?

This article announces the arrival of the Emergency Mitigation Service, with some companion commandlets.

Microsoft takes security very seriously and we continue to work hard to protect your systems and data from cyber threats and to comply with evolving regulations. In line with this, we have introduced the Skype for Business Server Emergency Mitigation Service to help protect your servers from potential threats. This service provides a temporary and interim mitigation until you can install an update that fixes the vulnerability.

The new cmdlets are:

New/Set-CsAdfsApplicationForSFBWebApps
Clear/Get/Repair/Set-CsMitigation
Get/Set-CsMitigationConfiguration
Get/Set-CsMitigationTelemetryConfiguration
Test-CsMitigationServiceConnectivity

What’s Changed?

Nothing noted.

Known Issues

After you uninstall this update, the standard MACP user sign-in URL (“https://<your pool FQDN>/macp”) fails. Instead, you have to use the following URL to sign in to MACP:

https://<your pool FQDN>/macp/

Note the now critical trailing slash. I tested this without the trailing slash and it worked, so I don’t know if this is an old notice that’s now obsolete, or still relevant in some scenarios. One to note regardless.

Download

Don’t forget to run bootstrapper, as that’s when the new EMS is installed. You’ll usually find bootstrapper in C:\Program Files\Skype for Business Server 2019\Deployment\.
