I have received a question on Exchange 2013 about the syncing of personal contacts in Outlook on GAL. For example, a user that has their own personal iPhone contact were uploaded to GAL. Obviously, a lot of users don’t like that (having their personal contacts loaded into the company directory).
During the research on ‘How do I block or stop the syncing of personal contacts with Exchange 2013 so they do not show up in outlook?’ I have found as ‘Social Connectors‘ are playing the game and automatic update of contacts are enabled by default.
How to change the settings?
In Outlook 2013 Social Network Account can be seen here:
In Outlook 2010: Go to View-> People->Account Settings->Settings button. Change the option from ‘Update without prompting’ to ‘Prompt before update’ or ‘Never update’
In Outlook 2003 or 2007: Account Settings can found at Tools, Social Networking Account settings
The registry settings are found at the following section:
We were talking about individual accounts and most of the time it requires to work on multiple users and GPO is the way for that. Change the Outlook settings via GPO will help.
The GPO can be found as applied at the following section:
Outlook –> Outlook Social Connector-> Block Global Address List synchronization
Value: 1 (no sync)
