A user emails the helpdesk requesting access to shared drive \\mnthyreportsclinic. This shared drive does not exist, however a shared drive \\monthlyreports does exist. Email the user requesting clarification.

Ooooo I know this one:

Dear (L)user.
The Shared driver you have requested access to does not exist.
Now would you care to engage brain and try again.
