Hmm I'm a little confused about ntfs and mapi rights. Went to create a public folder tree. At the bottom level was to be a shared calendar so I did all the creation through outlook. But of course when I set the user's rights to owner at the top level it didn't flow down.
Now as per https://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_21582610.html?qid=21582610&qid=21582610
in ESM you can propagate the ntfs rights down but how do you get the MAPI rights to flow down.
Or should I have created the folders via ESM - given him ntfs rights and then created the calendar in outlook and given him rights there also?
