I have a customer who I believe is having a permissions issue. She is running Windows XP Pro on a Server 2003 SBS domain. She is logged in as an administrative user. They are using Exchange 2003. Everyone at that company has their own mailbox, as well as access to public folders and a public calendar. She is listed as the user who manages the calendar, yet she can't make any changes to the calendar and cannot add anyone to their "management team" distribution list. I'm having a hard time trying to figure out why she can't do these things when it appears she has the correct permissions. Where can I go to check these things out?
