Outlook Social Connector Update interval

I really like the Outlook Social Connector and I use it in conjunction with your Social Media Updates Search Folder tip to quickly see what my contacts have been up to lately.

However, I noticed that this info isn’t always fully up-to-date.

How often does the Outlook Social Connector check for new updates and is there a way to change this interval or force an update similar to pressing Send/Receive to check for new emails?
