I have a user who gets 2-3 .xls attachments in an e-mail a day and she is unable to open any of them, it gives her the following error: Cannot create file: Offspec.xls. right click the folder you want to create the file in, and then click Properties on the shortcut menu to check permissions for the folder. She can forward the e-mail to me and I can view it no problem, and if I save the file to my computer, open it with excel, then save it and rename the file offspec.xlsx then attach it to an e-mail and send it to her she can view it. How and what do I need to correct so that she's able to open the .xls attachment? I have also checked folder options and made sure the proper program was selected to open the file with and it is set to 97-2003 Worksheet.
