After upgrading from Office 2003, whenever I launch Outlook 2007 a blank Word window opens - much like it did in Outlook 2003 with Word set as my email editor. Does anyone know how stop this from occuring?
I have seen this glitch before (relating to upgrades). The way I fixed it was uninstalling Office 2007 and making sure Office 2003 is uninstalled as well. It seems to be a problem with the upgrade process. Once all the files related to either version are gone, try a fresh install of Office 2007. This should fix your problem.
