Do i have to replicating the Public Folder before Configuring Schedule Free Busy ? or Configuring Schedule Free Busy only by InterOrg Utility ? - i need to make this as general open service between both forests not only 2 accounts; to be more clear i want all account in forest A be able to see forest b Calendar if needed When i checked the InterOrg it request the mailbox name ?

Hi,all account in forest A be able to see forest b Calendar if neededSo you mean you want to share calendar between two different Exchange Organization.Please notes:Although you can synchronize free/busy information across forests and use it to schedule meetings, you cannot use the Open Other User's Folder feature in Microsoft Office Outlook to view the calendar details for a user in another forestFrank Wang
