How to Convert Dynamic Distribution Group to Normal Distribution Group in Exchange 2010 & 2013

In some instances we had to Convert Dynamic Distribution Group to Normal Distribution Group .

In order to Sync in Office 365, in few other scenarios we had to do this as well

Lets see how to do it.

I would prefer to Create a  new Distribution Group with the same filter. where deleting and recreating might create some cache issues and NDR issues

Lets say I have a dynamic Distribution Group with the Name DG1

Its has a filter “CustomAttribute1 –eq CareExchange”

S

 Step 1:

Save the Dynamic Distribution Group to a Variable

$DynamicDG = Get-DynamicDistributionGroup “DG1”

Step2:

Now run the below Command to list the Existing members of the Dynamic DG

Get-Recipient -RecipientPreviewFilter $DynamicDG.RecipientFilter

Now Save the Members in a Variable

$DG1Members = Get-Recipient -RecipientPreviewFilter $DynamicDG.RecipientFilter

Step 3:

Now Create a New Distribution Group

New-DistributionGroup DG1Cloud

Adding the DynamicDistributionGroup members into a New Distribution Group

$DG1Members | foreach{Add-DistributionGroupmember DG1Cloud –Member $_.Name}

Verifying the members of the New Distribution Group

Now you got a Copy of your Dynamic Distribution Group safely Created as a Normal Distribution Group

Depends upon your situation , You can delete the existing one and Rename the Newly Created one.

and Make sure you are not going to get into Outlook Cache issues.
