Can't edit exchange 2010 distribution group.

We have migrated our exchange 2003 to exchange 2010 and before the migration the user was able to edit and make changes on the distribuition group from the user's outlook, now it says that it does not have permissions, any ideas, I've looked ta the distribution group and the only thing I've found was managed by and the proper user shows there but the user can not make any changes.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. 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.

Is there a way to verify if it has been done? I did not do the migration myself.

I have just re-read your first post, presuming you can edit the address lists in the EMC then this step must of already been done

Yes, we can make changes in the exchange console but not from the user's outlook.

Ok, so just wanted to confirm did you upgrade your DLs to Exchange 2010.

Set-DistributionGroup –identity “groupname” –ForceUpgrade

Above is command which will upgrade your DL to Exchange 2010. Try this and replicate your AD. Then update your GAL.

On the other hand, please check DL permission from AD once.

Go to ADUC--Click on View Menu and highlight Advance View -- then search DL -- then go to Security tab -- click on Advanced -- find the manager's name of DL -- and check it has permission with "This Object only" or "This object and Descendent Object only".

Second one will work for you.

If all are good then try configuring a new outlook profile then check, also you change outlook mode to online then try.

Amit KumarCommented:
Open Exchange Shell then run

Set-DistributionGroup –identity “groupname” –ForceUpgrade

Once this is done, open Command prompt with Run as Administrator and run below command

repadmin /syncall /Aeqd

Then open Exchange console --> Organizaton Configuration --> Offline Address book --> which is default there right click on it and update.
