We have a few email adresses which are used bij several people, i.e. firstname.lastname@example.org. We add this mailbox as an extra mailbox within Outlook of the user and that always worked. In the old days with Exchange 2003 and Outlook 2003 we used to add rights to these mailboxes by creating a distribution group and adding members to that group within AD. Then we added the distribution group to de permissions tab in Outlook on de inbox folder and gave this distribution group the owner rights.
Now we have Exchange 2007 and Outlook 2007. We do exactly the same, but when adding the distribution group in de permissions tab of inbox there is a forbidden symbol throught the distribution groups, when CAN add users, nut no groups.
Anyone any ideas?
