DanMerrill Posted July 19, 2017 Share Posted July 19, 2017 Does anyone use Microsoft Project? A month ago I have created one mpp file. Project was working well at the beginning, but now I am struggling with error message, An unexpected problem occurred .The file may be damaged. What does this message mean? Is there something I can do myself to recover Project file? Quote Link to comment Share on other sites More sharing options...
