Netscaler with Exchange 2016 OWA – Logoff Issue

Hello everybody,

Recently I was able to collect a new experience with the NetScaler (v. 11) and Exchange 2016 OWA.

Pre-Authentication at NetScaler enabled / OWA Exchange 2016

Problem Description:
A user successfully logs on to NetScaler (Pre-Auth) and will be automatically redirected to the OWA site, where the countless messages are displayed.
the user wants to log out now by logoff button in OWA, nothing happens. Only through a page refresh (F5) is again shown the NetScaler Logo site.

When you press the logoff button, a number of chunks is generated for the cancellation. These requests take the form of HTTP1.1 Protocol. (Focus on the version)

Through an analysis of Citrix, the problem could be solved.
In order for these chunks do not get in this version for NetScaler and lead to difficulties, a rewrite Policy on the NetScaler is created which changes the HTTP version of 1.1 to 1.0.
Here is the command for the configuration.

add rewrite action logoffIssue replace http.req.version “\” HTTP / 1.0 \ “”
add rewrite policy logoffIssue_pol true logoffIssue
bind rewrite global logoffIssue_pol 10 NEXT -type REQ_DEFAULT

Local Apps with XenDesktop 7.6 / Receiver 4.3

Hello all,

Firstly some information about the environment:

Storefront: Version 2.6
XenDesktop 7.1
Session Host OS: Windows Server 2008 R2


We use the KEYWORDS: “prefer” to use some locally apps on the Server. It works fine with the Citrix Receiver 4.1, it starts the app local in the same session as the desktop session….We use the Selfservice Store of the Receiver and not the Startmenue…

If i update for a test the Citrix Receiver to for example 4.2.100 or newer, the “prefer” function doesn’t work any more. I tried it with the registry key “PreferTemplateDirectory”, but without success. ( )

But, if i remove the app in the receiver and re-add it back to the main window, it starts locally…sadly only till i logon new, after that it starts the app in a new session and not locally.


I opened a ticket on the Citrix Support. After some analyses and tests we created a log of all. A few days later i received the solution. They send me a private Hotfix (old service plugins files).
whith the private Hotfix, everything works now as before.


RDS – It was not possible to start Apps in different collections

Infrastructure:  RDS 2012 / Windows Server 2012
Client: Windows 7 SP1

I had the issue, that the customer couldn’t start published Apps (for example notepad) of another RDS collection, if it is already one (for example calculator) started in a different one. If the user close the published app (calculator) and starts the other app (notepad), which didn’t work before, the it starts. But it was not possible to starts the apps of different collection togher.

Reason for this issue was some missing Microsoft Hotfixes. If you install the following MS Hotfixes, then it works:

Citrix UPM / Firefox settings

If you use Citrix Profile Manager in combination with Firefox, then it will not save the Firefox profile with all the settings (for example favorites), because this settings are saved in the local folder of the roaming profile which will be ignored after the logoff and not saved in the UPM profile.

For this issue you should create a Citrix Policy, where you could setup, that should < mirror > this setting to the UPM profile.
