Troubleshooting Steps 

  1.  Recycle the Information Store Services
  2.  Make the disk hosting the database offline from diskmanagement.msc and then bring it on line . This would release the lock on the database
  3.  Verify if the database is in cleanshutdown state (eseutil /mh databasename). If the database is in dirty shutdown state, run eseutil /r E01(Log file prefix) /l logfile path to replay the log files and make sure the database is in clean shutdown state
  4.  Mount-database <databasename> if the mount fails Proceed step 5
  5.  Disable/Uninstall the antivirus on the server / Verify the AV exclusions
  6. Change the log folder name and try mounting the database
  7.  If you are not able to change log folder name, Download Procmon and check process locking the log file path
  8.  Change the Database Log folder Path and try mounting the database
  9. Reboot the server
