When you open an email message or view a message in the reading pane, the Add button is missing from the People Pane. Therefore, you are unable to associate any currently installed providers for the Outlook Social Connector (OSC) with the contact displayed in the People Pane. The following figure demonstrates this problem.
This is expected behavior of the Outlook Social Connector when both of the following items are true:
Please use the following steps so you can configure social network providers in the current profile.
Note: If you are using a Microsoft Exchange Server mailbox, you must use a cached mode profile to see contact information in the People Pane. If you use the steps provided below and you still do not see the Add button in the People Pane, verify your profile is in cached mode.
Outlook 2013 and Outlook 2010
Note If you do not receive the prompt shown above in step 2, you probably saw the prompt at an earlier time and you clicked No to the prompt. In this situation, we recommend you create a new Outlook profile to regenerate the prompt shown in Step 2.
The first time you start Outlook after installing a social network provider for the Outlook Social Connector, the following registry data is configured by Outlook.
Value: name of your current Outlook profile
If you subsequently start Outlook with a different profile, the above registry data prevents any currently installed social network providers from appearing in the People Pane or the Social Network Acccounts dialog box. This design is intended to keep your Outlook profile configuration separate from the Outlook Social Connector. For example, you may have one Outlook profile for your personal email and another Outlook profile for your work email. In this situation, you do not necessarily want to have social network synchronization configured for both profiles.
