Outlook 2010 and/or EV Add-in issue
This is most likely not an EV add-in issue but if anyone have seen this behaviour before and found a solution, then that would be excellent.
IHAC where the administrator have issues on one of his machines, so everything works on two other systems but on one it doesn't.
The issue is that when he double clicks on an archived mail a window popup which says that it can't open the item.
Open items via Search works without issues.
I've done a client trace but I can't even see the download request in the trace so I suspect that the request don't reach the add-in itself.
The add-in is enabled (checked via trust center) we have tried a uninstall/install and resetevclient, new mail profile, no new events in the eventview and so on.
Still the same issue.
The only thing that I know for sure is different on this machine is that he has tested the next release of Outlook (beta) on it, that version have been uninstalled and he now uses Outlook 2010. So it may be some leftovers from that beta that causes this issue but again I'm not sure.
Anyway, since this is localized to just one machine there is always an option to re-install it.
But it would be great if someone have suggestions on how to avoid that step.
