I'm in the midst of upgrading users from Office 2003/7 to Office 2013 and Office 365/Exchange Online on Win7x64 machines. With some management positions wanting to sync their calendars to mobile devices, I had a user whose calendar was receiving multiple (like hundreds) duplicates syncing from a 3rd party smartphone app. Although I don't write code and had never used Outlook's VBA Editor, I did get this to work perfectly on the user's profile after a few false starts (was missing a reference library).I just used this for a second time while merging an old.pst file with a synced Exchange account; I needed to copy the calendar over to the new Exchange profile, but the user had already added some (duplicate) appointments. This tool made it a breeze and I'm not picking through the calendar for hours manually removing duplicates.LookForDuplicates has earned a permanent spot in my IT toolkit!
