EXODistributionGroup: Add HiddenFromAddressListsEnabled parameter and support for other attributes

[Borgquite]

Details of the scenario you tried and the problem that is occurring

EXODistributionGroup does not support various parameters (it appears to only support those available with the New-DistributionGroup cmdlet, but there are many more under Set-DistributionGroup)

https://learn.microsoft.com/en-us/powershell/module/exchange/set-distributiongroup?view=exchange-ps

It would be really helpful to have HiddenFromAddressListsEnabled available - but other relevant fields should also be included?

• AcceptMessagesOnlyFrom
• AcceptMessagesOnlyFromDLMembers
• AcceptMessagesOnlyFromSendersOrMembers
• BypassModerationFromSendersOrMembers
• CustomAttribute1 through CustomAttribute15
• EmailAddresses
• ExtensionCustomAttribute1 through ExtensionCustomAttribute5
• GrantSendOnBehalfTo
• HiddenFromAddressListsEnabled
• MailTip
• MailTipTranslations
• RejectMessagesFrom
• RejectMessagesFromDLMembers
• RejectMessagesFromSendersOrMembers
• ReportToManagerEnabled
• ReportToOriginatorEnabled
• SendOofMessageToOriginatorEnabled
• SimpleDisplayName
• WindowsEmailAddress

Suggested solution to the issue

Implement the ability to get, set and test these attributes when distribution groups are created/updated

The DSC configuration that is used to reproduce the issue (as detailed as possible)

Configuration Example
{
    param
    (
        [Parameter(Mandatory = $true)]
        [PSCredential]
        $credsAdmin
    )
    Import-DscResource -ModuleName Microsoft365DSC

    node localhost
    {
        EXODistributionGroup 'DemoDG'
        {
            Alias                              = "demodg";
            Ensure                             = "Present";
            HiddenFromAddressListsEnabled       = $True;
            Name                               = "DemoDG";
            Credential                         = $credsAdmin
        }
    }
}

Similar to #3089

The newly released EXOGroupSettings resource handles these parameters.

@NikCharlebois I don't think the module will work for distribution groups (-DistributionGroup cmdlets) since it only uses Microsoft 365 group cmdlets (-UnifiedGroup cmdlets). This would need either a separate resource, or a switch statement using Get-Recipient first then keying off RecipientTypeDetails (see below). However if you want to do it in one module bear in mind that a UnifiedGroup and DistributionGroup can share the same DisplayName since they're different object types, plus they support different sets of properties.

I'd suggest another module (could be a copy/paste job) as otherwise you'll have to do checks to make sure a user doesn't try to apply a UnifiedGroup only property to a DistributionGroup, and vice versa. But up to you.

RecipientTypeDetails = MailUniversalDistributionGroup or MailUniversalSecurityGroup -> *-DistributionGroup cmdlets
RecipientTypeDetails = GroupMailbox -> *-UnifiedGroup cmdlets

@NikCharlebois Let me know if you want to re-open this - or would prefer for me to create a new issue

Looks like a significant number of these attributes were added in 1.23.1004.1 - thank you!
