Recently, one of our users was outside of the office at a coffee shop using his netbook to vpn into work. He was using our citrix web interface and had Outlook 2007 opened remotely. He spent several hours composing a message in Outlook and then sent it to himself (to his own exchange mailbox). After doing so he noticed that his citrix web session had timed out. He then periodically checked his exchange mailbox the rest of the afternoon (both through the vpn and on his blackberry) and the message never showed up. I've looked in his sent items, drafts, and outbox and found no trace of this message. I also tried message tracking on our exchange server and found nothing.
So...Is there any other place this email could be hiding? Would the Citrix Web Session timing out have anything to do with the message disappearing? I didn't think the web interface timing out had any effect on programs that were already opened remotely. But I could be wrong :)
And a second issue that's related to this: our users hate the fact that the Citrix Web Interface times out without much of a warning. On our setup the interface will tell them that their session is about to expire, but they have to be looking at the web page to see the warning and usually they have a remote program open over the top of it. I know that you can increase the session timeout, which we've already done. But is there a way for the user to get a more obvious warning? A pop-up would be Ideal. Any other suggestions are welcome too.
