Quick update - I have now run re-installs of Office (Outlook) and repair, downloaded all updates, re-booted, and all the other really basic things I could think of doing. Outlook now gets past the splash screen and shuts down. Help!
Thanks Cindy but that can't be what's causing the problem for us, looked for the update first, then searched by the KB number, it's not on the latest updates we have. What area did you find it in?
Decided to try a full system restore, that has worked, so we are now back to where we were. Altered the windows set up so it now has to ask permission to do any updates, will look for fixes to the problem the latest updates caused before we agree to any more.
Thanks for your suggestion, I will keep a look out on the forums for any further information on this issue.
