Not sure what's going on here. I just noticed that the shared contacts have multiplied in the webmail (not in Outlook). It may have happened after the 6.0.2 upgrade, but I can't be certain. It also hangs when viewing the shared contacts. I've tried deleting and re-adding the shared contacts, but I get the same problem.
The screenshot shows the contacts as viewed by the user who has linked to the other user's shared contacts. From the sharer's account, everything looks normal.
What's going on here?
