We're experiencing a strange issue in our Citrix Environment where users can't click to open attached files in Outlook.
We host a XenApp 6 farm with multiple customers using pretty much the same setup and the issue we're having is only affecting one customer. What happens is that every now and then, not every time, when they log in and start their Outlook they can't open attached files. Actually the interface doesn't even seem to acknowledge there is a attached file given you can't even click it to mark and preview it while you at the same time can click and mark the message field. If you continuesly click the attached file it usually does open but that can require anything between 2 and 30 clicks.
We've checked Citrix Policys, GPOs and the terminal servers themselves for things that distinguish this customer from all our other customers who don't have the problem. I've also tried different receiver versions with different graphical settings but haven't find anything conclusive. It does seem that when we RDP the server with the user information it always works though so somehow this is connected to the Citrix software either on the client or on the server. What's also worth noting is that when I give myself access to the customers TS servers through their published desktop it works for me every time while a collegue using the same kind of computer I do had the issue.
It does seem that they've had this issue for quite some time but it's become more apperant when they've started to but it's become more apperant when theyäve started buying new computers going to Laptops instead of using Thin Clients.
I'm pretty much baffled and I would love to hear any input on this issue so we can solve it once and for all.
