Vulnerability discussion

Administrator responsibilities include the ability to react to unplanned maintenance tasks or emergency situations that may require Public Folder Store data manipulation. Occasionally, there may be a need to start the server with "unmounted" data stores if manual maintenance is being performed on them. Failure to uncheck the "do not mount on startup" condition will result in unavailability of Public Folder services.Correct configuration of this control will prevent unplanned outages due to being enabled. When maintenance is being performed, care should be taken to clear the check box task completion so public folder stores are available to users (unmounted public folder stores are not available to users).

Check content

If public folders are not used, this check is not applicable. Open the Exchange Management Shell and enter the following command: Get-PublicFolderDatabase | Select Name, Identity, MountAtStartup If the value of MountAtStartup is not set to True, this is a finding.

Fix text

Open the Exchange Management Shell and enter the following command: Set-PublicFolderDatabase -Identity <'IdentityName'> -MountAtStartup $true Note: The value must be in quotes.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
