We have a group mailbox that needs to be accessed by several people. I set up the mailbox. Logged in to it and set up the deletegate by group and by indivudual user. I tried to open add the mailbox to their account and it shows up, but when the user attempts to access the box it doesn't allow them to. When I do it in my Outlook it works fine (but I am an exchange admin). What do I need to do to give them the access they need.
Running Exchange 2007 on a WinServer 2008 (64bit) OS, single domain, single organization.
