Just a few weeks ago I noticed that I have duplicate entries for all of my
contacts. I only see the duplicate entries if I search for a name. Example
using the "address book" toolbar window I enter a name "jackbone" and in the
search results window I see two entries. If I open the first and then run
another search and then open the second I see that they are actually two
different entries. When I look at the properties for each entry I see that
they are both in the Location "Contacts" but the Size is different for each.
In OL if I click on the "Contacts" icon in the left nav pane and open the
contacts I don't see double entries. In the menu if I click on File and then
select "Data File Management" I only see "Archive Folders" and Personal
Folders". I use Active Sync to sync to my phone, the other day I was forced
to create a new partnership and when I came time to sync the data I picked
the option to replace everything on the phone with what was in OL, I then saw
a message that 2900 contacts were being synced. I'm sure that I don't have
more than 1200 contacts. On my phone when I look up a contact I only see one
entry for each person.

Just as a test I updated the first "jackbone" entry (in the search results)
by changing the phone number. On the PC only the first entry was updated. On
the phone I see the updated phone number and do NOT see the duplicate entry
(never did) with the incorrect phone number.

Any suggestions?
