Issue   You see duplicate contacts in your Microsoft Outlook default Contacts folder, in Microsoft Lync 2010 search results, or in both places.

Resolution   By default, Lync 2010 adds contacts to the Outlook default Contacts folder, which can cause duplicate contacts in Outlook and in Lync search results (because search pulls from the Global Address List, or GAL, and from your Outlook Contacts folder). To resolve these issues, disable this behavior by doing the following:

  1. In the upper right corner of the Lync main window, click Options (gear icon).

  2. In the Lync - Options dialog box, click Personal.

  3. Clear the Save my Lync contacts in my personal contacts folder on the Exchange server check box.

Then, to manually delete the duplicate contacts from Outlook, do the following:

  1. In Outlook, in the navigation panel on the far left, click Contacts.

  2. On the Current View tab, in the Current View group, click Phone.

  3. Right-click the Full Name column header, and then click View Settings.

  4. Click the Columns button.

  5. In the Available Columns list, click Modified to highlight it, and then click the Add -> button.

  6. Click OK, and then click OK again.

  7. Click the Modified column header to sort by ascending or descending order to group the contacts that you want to delete.

  8. Click the first contact you want to delete.

  9. Scroll down to the last contact you want to delete.

  10. Hold down the Shift key, and then click the last contact you want to delete to highlight them all.

  11. Press the Delete key.
