Virtual Vault (Can't move the items. You don't have appropriate permission to perform this operation.)
I wanted to post this error because it is a little vague. When moving items from Outlook or PST's you might get this error for a couple of reasons:
Make sure you have a calendar in Virtual Vault (create a blank Calendar) Calendar items will not be ingested if you do not have some place to put them
Make sure all IPM. files are added to the Admin Console under the Directory Exchange Message Classes tab. Here is a link to the Microsoft Message Classes. http://msdn.microsoft.com/en-us/library/bb176446.aspx
Make sure you Virtual Vault size is large enough to handle all the items you are putting into it. You can change this under the Desktop Policy \ Vault Cache Tab.
