I have an windows outlook 2010 pst file that I imported into mac outlook 2011. I used the import feature of outlook 2011. It ran ok, indicated no problems. When I looked at my contacts I found that all or almost all contacts are repeated several times. The first attachment shows my mac outlook left pang and the second shows my windows outlook.



Why was so much stuff duplicated?

Based off your outlook 2010 screen shot, there are three Contacts - Outlook lists. if these lists contained the same data then you would have duplicates.

- Are you on an exchange server?
- When you export your contact list to .CSV file, from Outlook 2010 are they duplicated?

Outlook 2011 does not have an do not import duplicate function. However, outlook 2010 does. using this work around you could eliminate duplicates from a .PST or .CSV file.

Keep me posted
