Hi, We are using outlook 2011 on one of the iMacs here (Snow Leopard 10.6.7). Today it randomly threw up an error and crashed. MS Error reported asked if we wanted to report the crash and restart the app. We selected restart and now the app is stuck in a loop of launching and crashing. We have tried uninstalling by dragging the office folder to the trash and then reinstalling, this gave exactly the same problem. We have now installed CleanMyMac and used this to uninstall Office 2011. Upon reinstallation exactly the same problem has occured again! I have searched online and no one else seems to be having this issue. I am guess there is some sort of config file or similar that may have got corrupted. This must live elsewhere on the mac and is getting missed by uninstallation. Does that sound right?
