Thanks for the response, but I don't think your understanding the issue. My USMT 4.0 is setup to migrate this information, and does so without much issue. On some machines, Outlook will not open unless I go to Control Panel -> Mail and re-enter the username, then click Check Name. Then it is detected without issue. My Question is this, what is the registry key that holds this information? If I had that I could modify it with a Script after the Restore of the users data.

Same here, has anyone found a solution to this issue yet?

Were you able to fix this issue? If so, how? I am having a similar issue with multiple partitions and the Task Sequence trying to apply the OS to the wrong one.
