Hello -

Active Directory is storing LAN Manager (LM) hashes of legacy user account passwords.  We are looking to change service account passwords to force Active Directory to no longer store the LAN Manager (LM) password hash. Some of ours still exist because the account hasn't logged in service account. For example, we have an account called calendar we used for setup, no one has logged in it since the day of setup. How do we go about removing it and others?

Delete the account if it's not used.

Disabling LAN manager hashes should have no negative impact unless you have something archaic which is explicitly reliant on that.
