Hi @eli ,
I tried to reproduce this locally, but was not successful.
Stopped Outlook and deleted GAB pst (to simulate a new profile)
Contacts in the GAB after pst was recreated 93, 130 & 8
Hit the gab resync in the settings.
Contacts in the GAB after the process finished 93, 130 & 8
Do you have a koe logfile for the initial sync?
