Consider the following scenario:
Users who have the %AppData% folder redirected to a network share notice that Lookup fields fail to populate correctly after selecting a record. In addition, users may notice that after selecting a record in the Lookup Field web dialog box, a red "x" will populate in the field instead of the record that was selected. This issue occurs in both the web and Outlook clients.
If a trace is ran on the Outlook client, the following error appears during this process:
>JavaScript Error: The system cannot find the file specified.

If the %AppData% folder redirection is disabled, the issue goes away.
