Convert 365 "Mail Enabled Security" group back to 'Distribution Group"

[Warwick_Tech]

Hi All,

 

I have an odd one; we need to convert some mail-enabled security groups back into old fashioned distribution groups;

 

Has anyone done this? As usual I can find instructions for one way but not the other.

Currently looking if I can reverse engineer one of these scripts

For anyone who needs it:

 

$DistributionGroupName = Read-Host -prompt "Type the Distribution Group name"

 

$Members = Get-DistributionGroupMember -id $DistributionGroupName

New-DistributionGroup -Name $DistributionGroupName-TEMP -Type Distribution

ForEach ($Member in $Members)

{

Write-host “NEW Distribution group named - $DistributionGroupName-TEMP created!”

Write-host “The Distribution group - $DistributionGroupName-TEMP contain all the members of the Distribution Group named - $DistributionGroupName”

Add-DistributionGroupMember -Identity "$DistributionGroupName-TEMP" -Member $Member.name

}

Remove-DistributionGroup -Identity "$DistributionGroupName" -confirm:$false -BypassSecurityGroupManagerCheck

 

$Members = Get-DistributionGroupMember -id $DistributionGroupName-TEMP

New-DistributionGroup -Name $DistributionGroupName -Type Distribution

ForEach ($Member in $Members)

{

Write-host “NEW Distribution group named - $DistributionGroupName created!”

Write-host “The Distribution group - $DistributionGroupName contain all the members of the Distribution Group named - $DistributionGroupName”

Add-DistributionGroupMember -Identity "$DistributionGroupName" -Member $Member.name

}

Remove-DistributionGroup -Identity "$DistributionGroupName-TEMP" -confirm:$false -BypassSecurityGroupManagerCheck

Set-DistributionGroup $DistributionGroupName -EmailAddresses SMTP:$DistributionGroupName@DOMAIN

 

What this does is make a temp group, delete the old group then re-create and delete the temp group. Clever, eh?
