When you try to rename an existing search in Microsoft Exchange Server 2010 Multi-Mailbox Search (Discover Search), you receive an "Invalid ResultPath format" error.


This issue occurs if there is a comma (,) in the Discovery mailbox name.


To resolve this issue, remove the comma from the Discovery mailbox name. Or, create a new Discovery mailbox that has no comma in its name. 

For more information about how to create a new Discovery mailbox, see Create a Discovery Mailbox.
