This “Take 2” at the November CU updates the Core and Web Components from 5.0.8308.974 to 5.0.8308.977, addressing this issue that snuck into the last update:

Kb3212869: Searching for a user on Lync Mobile returns no results after the November 2016 Cumulative Update for Lync Server 2013 is installed.

What’s Fixed?

Just the above.

What’s New?

Nothing apparently.

Download

• Download the installer from here
• Here’s the kb article – and the install procedure

Installation

Here’s the “before” view of it going on to my Standard Edition Front-End:

After you’ve run the installer & updated the databases (if required), don’t overlook the final few steps:

1. Enable-CSTopology – which will fail if you have SfB2015 co-existing, so don’t be frightened by the error “Command execution failed: “1” error categories reported in topology document.”
2. Fire off the bootstrapper: %ProgramFiles%\Microsoft Lync Server 2013\Deployment\Bootstrapper.exe
3. And if you’ve skipped an update or two, best run Update-CsAdminRole after you’re done to make sure the new commandlets added in previous updates are accessible when PS Remoting.

Reboot?

No, one was not required.
