Check in or discard changes to a file on SharePoint
If you want to change a file that is located in a SharePoint library and you do not want other people to access it, you can check out the file. In this manner, you will know for sure that no one else can change the file while you are working on it. When you complete your edits and check the file back in to the SharePoint library, other people can see your changes. It also becomes available to them for check-out, if they have appropriate permissions. If you decide not to make or keep any changes in the file, you can discard your check-out so that you do not affect version history.
You can save to a server that has Microsoft Office SharePoint Server 2007 and Microsoft SharePoint Server 2010 installed. To work with SharePoint in Office for Mac, you have to have Microsoft Office for Mac Home and Business 2011, Microsoft Office for Mac Academic 2011, or Microsoft Office for Mac Standard 2011.
