We are using it, and for the most part it works well. Currently we have 100 subscribers, and will get to about 500 within the next 6 months. Our Unity servers, Citrix servers, and Exchange server are all at our 2 central locations (100mb inter-connected), and we will have remote clients at 39 sites (Alaska and Washington).
Sometimes a new user has to set their ViewMail options several days in a row before it is remembered in their Citrix profile. A few users have complained about their Outlook client hanging for a few seconds as a new message is received. We are going to disable virus scanning for wav attachments to see if that helps. This is not a problem with a local PC Outlook client.
