Is it possible to share my calendar with a user in seperate forest. I am talking about Calendar folder not free-busy info. i am running Exchange 2007 and the other forest has got Exchange 2003, we alreat have trust established.

Hi,You cannot share your calendar with a user in another forest.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 MicrosoftOfficeOutlook to view the calendar details for a user in another forest.More detail,Cross-Forest Topology http://technet.microsoft.com/en-gb/library/bb124765.aspxFrank Wang
