Stephen Borrill@kasperd @jamesthomson @revk And in #Citrix tech support news, if they were still using that now and were using VHD profile containers to help with Outlook's PST files, then resetting those would be a good start if you had two Outlooks and neither on them worked...
@kasperd @jamesthomson @revk On the ISS, it was #Citrix XenDesktop for the desktop access and Branch Repeater to help with latency (uses lots of highly desktop-optimised caching). These are both the old product names.

aka "This is Bad™" 😁
plutôt que sur la version, réduisent considérablement le nombre d'appliances exposées.
