Exchange queue database must reside on a dedicated partition.
An XCCDF Rule
Description
<VulnDiscussion>In the same way that added security layers can provide a cumulative positive effect on security posture, multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit to one application can lead to an exploit of other applications sharing the same security context. For example, an exploit to a web server process that leads to unauthorized administrative access to the host system can most likely lead to a compromise of all applications hosted by the same system. Email services should be installed to a discrete set of directories on a partition that does not host other applications. Email services should never be installed on a Domain Controller/Directory Services server.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Remediation - Manual Procedure
It is recommended to follow the instructions found in the following documentation:
https://learn.microsoft.com/en-us/exchange/mail-flow/queues/relocate-queue-database?view=exchserver-2019
Set aside time for maintenance before correcting the issue, as this will affect mail flow through the Edge role on that server.
Open an Exchange Management Shell and use the automated script (shipped with Exchange) to move the queue database and its existing files to the new destination.
