WORKAROUND
To work around this problem, use either of the following methods.
Note Before you use either of the following methods, always save your document, workbook, or presentation to the shared folder before you create hyperlinks to other files in that folder. This creates the necessary base reference for the creation of relative hyperlinks.
1) : Manually Set the File Location
When you create the hyperlink, do not type the path, instead use the Link to File dialog box to create the hyperlink:
1. On the Insert menu, click Hyperlink.
2. In the Link to box, click Existing File or Web Page.
3. Click Browse for File.
4. Type the path to the network share, and then press ENTER to list the contents of that share.
5. Click the file you want to hyperlink to.
6. Click OK, and then click OK.
