SYMPTOMS

Consider the following scenario. You map a network location to a drive letter. Then, you use a Universal Naming Convention (UNC) connection to open a workbook from the network location. For example, you use the following UNC connection to open the workbook:
\\share\folder\filename.xls
In this scenario, references to a hyperlinked workbook may use a drive letter location. Additionally, may receive unexpected results.

For example, you may experience the following symptoms:
  • If the following conditions are true in the workbook, you receive unexpected results:
    • The workbook contains an INDIRECT field.
    • The INDIRECT field references a cell that contains a hyperlink to a cell that is in another workbook.
    In this situation, you receive a #REF! error message in the cell that contains the INDIRECT field.
  • If you click a hyperlink in the workbook to open another workbook, a drive letter is used for the location of the workbook instead of the UNC location.
