Fixed itWhat I was trying to do was get the IM working from OWA.What I had to do was install the latest hotfix from MS on the exchange server for UcmaRedist http://www.microsoft.com/downloads/details.aspx?FamilyID=B3B02475-150C-41FA-844A-C10A517040F4&displaylang=en&displaylang=enWhat I also did was remove the UM role from exchange and install some of the office communicator web access stuff on the exchange server prior to doing the aboveNot sure which one of these fixed it but it didnt start working until i installed the hotfix(im pretty sure I tried to install this before but it failed as it said it was installed)Robbie
