Recently we moved across a user and a distribution list from Exchange 2003 to 2010. The user used to be able to add and remove from a distribution list within Outlook.
I have added them to the Managed by list in Exchange in the distribution list, but to no avail. They are getting an error message saying You do not have the sufficient permissions to perform this operation on this object.
I cannot seem to find the setting to allow the user permissions.
