I run Exchange 2013 on windows 2008 R2 - I have several distribution groups that work fine but unfortunately one of the distribution groups being used to house the several other distribution groups (for a single email to all) is actually a security group - yes it has all the other distribution groups in it.

Today I tried to enter several single users to this group and it tells me:

Error You dont have sufficient permissions. This operation can only be performed by a manager of the group

When I go to power shell and do a:

Get-DistributionGroup | fl name,managedby

I get back:

Name      : Nameofmygroup - All
ManagedBy : {}

I am logging into the of the windows 2008 R2/Exchange 2013 with the administrator that I used to create both. When I go through EAC to the group and click on ownership there is nothing there - when I try to add the administrator account it tells me the same thing:

Error You dont have sufficient permissions. This operation can only be performed by a manager of the group

I probably should just delete and re-create it as a distribution group, but there has to be a way I (being the administrator) can take control of this group be it a security or distribution group.

Thanks in advance for any help

Hi,

From your description, I recommend you use the following cmdlet to set the distribution group owner and check the result.

Set-DistributionGroup xxx -ManagedBy "administrator@contoso.com" -BypassSecurityGroupManagerCheck

Hope this can be helpful to you.

Best regards,
