Note: This is not needed for Exchange 2016 or later, however you will need to modify the Role Assignment in CloudPanel under the Advanced section on the Exchange tab in the CloudPanel settings.
By default users will be able to see other company’s distribution groups when they are logging into the web interface. To resolve this we either need create an alternate role or modify what features are in this role. To begin open the Exchange Management Shell and enter the follow commands (make sure you Exchange environment is fully patched):
New-RoleAssignmentPolicy "Alternate Assignment Policy" New-ManagementRoleAssignment -Name "MyContactInformation-Alternate Assignment Policy" -policy "Alternate Assignment Policy" -role MyContactInformation New-ManagementRole "MyBaseOptionsWithoutMessageTracking" -Parent MyBaseOptions Remove-ManagementRoleEntry "MyBaseOptionsWithoutMessageTracking\Search-MessageTrackingReport" New-ManagementRoleAssignment -Name "MyBaseOptionsWithoutMessageTracking-Alternate Assignment Policy" -policy "Alternate Assignment Policy" -role MyBaseOptionsWithoutMessageTracking
