10 users are not able to access their mailboxes.

I ran Get-MailboxDatabase & checked database is Dismounted. I tried to mount it but it failed.

I ran ESEUTIL/mh
State: Dirty Shutdown

Next, I ran ESEUTIL /r

Operation terminated with error -1032 (JET_errFileAccessDenied, Cannot access file, the file is locked or in use)

Please help it is urgent!
