Hi,
Yesterday Microsoft released updates for Outlook 2010 and Outlook 2013 (oem and click2run).
Based on our internal test results, we came to the conclusion that the advanced collaboration features are not functional after installing the updates.
The results are presented here below:
Outlook 2010 OEM 14.0.7166.5000
7.2.1-52036 - advanced collaboration features not functional after the updates were installed
7.1.14-52028 - advanced collaboration features not functional after the updates were installed
Outlook 2013 OEM and click2run 15.0.4797.1001
7.2.1-52036 - advanced collaboration features not functional after the updates were installed
7.1.14-52028 - advanced collaboration features not functional after the updates were installed

With our latest clients these advanced collaboration features are restored;
For ZCP 7.1, please install ZCP 7.1.14-52042
For ZCP 7.2, please install ZCP 7.2.1-52041

They can be downloaded via our portal.
If you have an Outlook version that displays a different kind of result than published here, please contact us.

Cheers,
-Suyi
