How do I share a workbook and allow user to save?
 

Prior to computer trouble, users were able to access the workbook and save
the changes. Since we got the computer back, the file is able to be accessed
but it will not allow users from other computers to save the changes made.
The file is shared on the network as it was before. But when trying to save,
it asks them to rename the file to save. Does anyone know what could cause
this or how I could fix it?
Thanks!
