I have a user that recently got office 2013 pro plus on his computer.  We created a new profile and connected him to exchange 2010.  Now when he tries to open up a calendar item that was created prior to the 2013 install it just spins and you have to cancel outlook.  He can create new calendar items and then open them up again but any item that was created with 2007 locks up.

Any ideas?

Thanks
