Full path to the report file that you want to generate. If this is not specified, a directory in your current users AppData is created called ORCA. Reports are generated in this directory in the following format: ORCA-tenantname-date.html .PARAMETER NoUpdate Optional. Switch that will tell the script not to exit in the event you are running an outdated rule definition. It's always recommended to be running the latest rule definition/module. .PARAMETER NoConnect Optional. Switch that will instruct ORCA not to connect and to use an already established connection to Exchange Online. .PARAMETER Collection Optional. For passing an already established collection object. Can be used for offline collection analysis. .PARAMETER AlternateDNS Optional. Allows you to specify a DNS server which will be used in any checks requiring resolving a hostname. This can be useful if you are using split-DNS, and have alternate DNS servers for the public domain. .EXAMPLE Get-ORCAReport .EXAMPLE Get-ORCAReport -Report myreport.html .EXAMPLE Get-ORCAReport -Report myreport.html -NoConnect #> Param( [CmdletBinding()] [Switch]$NoConnect, [Switch]$NoUpdate, [Switch]$NoVersionCheck, [String[]]$AlternateDNS, $Collection, $Output ) # Version check If(!$NoVersionCheck) { $VersionCheck = Invoke-ORCAVersionCheck } # Unless -NoConnect specified (already connected), connect to Exchange Online If(!$NoConnect -and (Get-EXConnectionStatus) -eq $False) { Invoke-ORCAConnections } # Build a param object which can be used to pass params to the underlying classes $ORCAParams = New-Object -TypeName PSObject -Property @{ AlternateDNS=$AlternateDNS } # Get the object of ORCA checks $Checks = Get-ORCACheckDefs -ORCAParams $ORCAParams # Get the collection in to memory.
