The hidden gray icon appears after you close outlook and will disappear after outlook finish to close the ost/pst file. It is normal if you have large ost/pst file. After you close outlook wait until the gray icon disappear and then try to open outlook again. Do not close outlook process from task manager. It will make “file data check” on the nest opening.
