How often do Contacts update? Is there any where to see the Contact sync results?

If your Schedule and Streamer is enabled, Contacts will update multiple times a day. The Streamer will look for updates about every 30–40min and push any updates it found. You can check for the synced results by doing the following:

1. Scroll down on the main dashboard until you see the mailbox list.
2. Find the user you want to check on.
3. Right click on their name.
4. Click View Sync Results.
5. Click Contacts.
