Durations appear with Question Marks in MSP

When the Microsoft Project (MSP) Schedule opens through PPM, all the durations show up with a Question Mark (?) at the end. 



This is due to having the MSP setting 'New scheduled tasks have estimated durations' checked. 




It's recommended to have this field unchecked, unless you are using estimated durations. To uncheck this field:

  1. In MSP, go to File->Options->Schedule
  2. Under 'Scheduling options for this project', uncheck 'New scheduled tasks have estimated durations'
  3. Click 'OK'
