title: What causes an excel file to open as read-only?
body: <p>An excel file exists on a network that can be accessed by several users.</p>
  
  <p>However, after some investigation it was found that some users open the file as read-only.</p>
  
  <p>I'm opening the file with VBA and workBook.Open(). This routine has a read-only property, but even explicitly sending this parameter as false, the file still opens as read only. When users who experienced this bug were asked to open the file straight from the network, the file opens as read only, despite being fine for other users. Additionally, permission rights to the folder has been ruled out as the cause.</p>
  
  <p>Does macro security prevent a file from being opened normally? What else can cause a file to open as read-only?</p>
