Convert mail enabled security group to distribution list

A nice Exchange question!

To convert a mail-enabled security group to a distribution list in Exchange, you can follow these steps:

Method 1: Using the Exchange Management Console

  1. Open the Exchange Management Console.
  2. Navigate to the "Recipient Configuration" node.
  3. Right-click on the mail-enabled security group you want to convert and select "Convert to Distribution Group".
  4. In the "Convert to Distribution Group" wizard, select the "Distribution Group" option and click "Next".
  5. Enter a name and alias for the new distribution group, and click "Finish".

Method 2: Using the Exchange Management Shell

  1. Open the Exchange Management Shell.
  2. Run the following command to convert the mail-enabled security group to a distribution group:
    New-DistributionGroup -Identity <GroupName> -Name <GroupName> -Alias <GroupName> -Type Distribution

    Replace <GroupName> with the name of the mail-enabled security group you want to convert.

Method 3: Using PowerShell

  1. Open PowerShell.
  2. Run the following command to convert the mail-enabled security group to a distribution group:
    Get-DistributionGroup -Identity <GroupName> | Set-DistributionGroup -Type Distribution

    Replace <GroupName> with the name of the mail-enabled security group you want to convert.

After converting the mail-enabled security group to a distribution group, you can manage the group's membership and settings using the Exchange Management Console or the Exchange Management Shell.

Note: Before converting the group, make sure to remove any existing permissions or access controls that are specific to the security group, as these will not be carried over to the distribution group.
