title: Access reference library goes missing after opened from newer version
body: <p>I have built an Access database that is shared on our company network. Most users on the network have Access 2010 installed but some have Access 2016. When the database has been opened by someone with Access 2016 and then subsequently opened by someone with Access 2010 they are getting an error message as the Microsoft Excel 16.0 Object Library is marked "Missing". </p>
  
  <p>I can fix this temporarily by selecting the '14.0 library' but the error recurs as soon as it is opened in the later version again. Is there anything I can do to stop this from happening?</p>
  
  <p>Thanks</p>
