We've found that Outlook doesn't do it's initial Send / Receive while Go Contact Sync mod is running. To test our theory we've shut Go Contact Sync down and opened Outlook and it does it's initial Send / Receive. If we leave Go Contact Sync running, when we open Outlook we have to click the Send / Receive button to initiate the first Send / Receive. Is there something in Go Contact Sync that would be blocking the initial automatic send / receive that Outlook does? We are using Outlook 2010 32-bit on Windows 7 64-bit with Go Contact Sync mod 3.5.20.
