Group without owner cannot remove members


I have an Exchange 2013 Standard standalone server running 2012 R2.  There is a distribution group that I need to remove a member from.  Doing so via ECP I get an insufficient rights-message.  Only owners can remove members from this group.  The group has no owners.  Needless to say I cannot make myself owner, either.  Also I cannot delete the group.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What you need to do is the following...
- Open ADUC
- Make sure that View>Advance Features (is enabled/selected)
- Find the Distribution Group, right click select Properties
- Click on the Security Tab
- Make sure that your account or a group that you are part of has Full Access to this account
- If it does not add it
- If this does not work, then click the Advance Security button
- click the Owner Tab and grant yourself owner for this  group
- go back into Exchange and see if you can modify the groups accordingly

Hi Will,

first:  I should have thought of this myself.
I was able to modify the user list of the group just fine using ADUC.  The rights to this group were granted to the domain administrators group, which was also the owner of the object.
Ich replaced the owner object by the administrator user.

Even though I can confirm that the change I did through ADUC is also shown in Exchange, I still cannot modify the group using ECP and ECP still shows the user list as empty.

What am I missing?

Found it.
It was not actually a distribution group but a security group.
Dumb mistake.  But thank you so much for pointing me into the right direction!
