BE 2014 tries to put the Exchange .edb for a restore job to C:\temp where there is not enough place for it. Options for GRT in BE 2014 are ignored, temp folder for restore ist set to D:\temp there.
If the staging area was changed and if the existing restore job is rerun, then it will default back over to the old staging area. Do setup and run a new restore job and the new staging location should be reflected.
