I've found a workaround for another issue I had, granting a user full access to a mailbox via console. The issue involved calendaring, however, full access only needs to be granted to the calendar, can this be done in the shell? Here's the other issue leeding to this. http://social.technet.microsoft.com/Forums/en-US/exchangesvrclients/thread/08da8953-2604-4205-8b11-f5d5e39c48d0 Set up as a sharee, the meeting organizer was unable to see her own meeting requests when she opened calendars shared with her while the calendar owner does see them. The above might not be ideal but is a workaround, if full access can be granted to just the calendar anyway. Thanks!

Hi,Actually folder level permissions inside mailbox can not be set with Powershell and I agree with Mike, an admin or mailbox owner needs to open mailbox to give calendar permission or admin can do it centrally on a mailbox or on all the mailboxes of serverwith PFDavAdmin(as per link given by Mike).Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
