Some Outlook contacts may be in your local cache, and cannot be migrated, nor will they be part of an export following the above instructions.

During the Early Adopter go-live, some people reported that some of their data was missing in Google. Upon investigation, we found that most of the time, the reason for this was that the missing data was not stored on the Exchange server, but was instead only resident on the individual's computer. Any local data of this type will need to be migrated separately following the instructions to Migrate Offline Mail Archives (PST or OLM files).
Below are some examples of the way email would appear if some of the data is local (local data circled in red):
