LinkedIn Integration (Postbox 3 and earlier)
LinkedIn support in Postbox was removed in Postbox 4. Why?
Postbox supports LinkedIn. Support includes pulling in contact photos, business titles and company names from LinkedIn. Additionally, you can post status updates to LinkedIn.
You can configure Postbox to use LinkedIn by going to:
OS X: Postbox > Preferences > Advanced > Web Services
Windows: Tools > Options > Advanced > Web Services
...and then logging into the LinkedIn service.
