title: Date format in Excel keeps changing for other users
body: <p>I created a project management tool in Excel to be used by the team on Sharepoint. In a table it is required to insert the date when a ticket was open, closed, etc. </p>
  
  <p>The problem with the date format is that in my machine (Office 2016) all dates appear as dd-mm-yyyy but to my colleagues (Office 2010) the dates inserted by me look okay but when they try to insert new ones it will appear as mm-dd-yyyy despite the fact that the formatted cells say "Locale: English (United Kingdom)" and dd-mm-yyyy. </p>
  
  <p>The region and language settings are the same for all users and there is no code running in the workbooks. How can I fix this?</p>
  
  <p>Thanks in advance. </p>
