This is a collection of tools used to remove duplicates from your Microsoft Outlook Contacts folder. Some of these tools will also remove duplicates from other Outlook folders.
When the duplicates are the result of importing and all are duplicated, you can sort by the modified date field (you'll need to add the Modified field to the view), then delete all of the items with the same modified date and time. When the duplicates have assorted modified times, you'll need to delete the duplicates yourself or use one of the many duplicate remover tools to automate the process.
Warning: Deleting duplicates in an Outlook.com account synced using Exchange Active Sync (EAS) can result in lost contacts. Export to a backup file first.
- If not using a list view, switch to a list view.
- Right click on the row of field names
- Choose Field Chooser
- Find the Modified field in one of the All <type> fields list.
- Drag the field to the row of field names and drop
- Sort by the Modified field.
Some tools, such as Outlook Contacts Scrubber, will merge the data on duplicate contacts to one contact. This is useful if you are combining contact lists from different computers and the data on the contacts are not identical.

Oh dear, what have I done? Downloaded Cosi for ipad, and saved Outlook 2007 calendar as it said as a pst file, then downloaded the Cosi toolbar to sync. All worked well. But then noticed all outlook appointments had blue square on them. So deleted Cosi off ipad, emailed them re my deletion, then deleted via Control panel Programs. Then reinstalled according to Cosi's directions and now I have a new calendar and an old calendar mixed up with old recurring appointments coming up all the time. I don't know how to remove them. I've tried deleting the old recurring appointments to no avail. Any ideas muchly appreciated?
In Outlook... is every thing in one calendar folder or in two? Normally, the best way to delete stuff from the calendar is using a list view but I'm not clear if the problem is in your default calendar in Outlook or with the sync process as I'm not real familar with the cozi app.
