I have installed your plugin in a Citrix XenApp servers environment, and in 6 servers work fine, but in one of them I can not install it.
When I run the installer, it finishes without error, but when I open Outlook, in the calendar section I can not see it. If I go to programs & features, I can see it and I can uninstall it , but I try to install it again , I get the same.
I have just downloaded the last versión from your website Lifesize.Cloud.Windows.Outlook.Addin.Bootstrapper+18.104.22.168.exe , but with the same result.
The operative system is Windows 2008 R1 English versión and Office 2016
Thanks in advance
