Poco FAQ - Found messages - Copied or moved

Q: After I perform a search, the messages found contining the text I'm looking for are placed in a new FOUND folder.

Are those messages copied or moved from the folder they were in? In other words, in order to keep them, do I have to move them to their original location, or can I just delete the mailbox with the messages in them, knowing they're still preserved in their original location?

 
A:
The "Search" mailbox is a system mailbox and cannot be deleted. Messages in this mailbox are linked to the master copy of the message. The implications of this are listed in this document.

The messages are copied, you can safely delete the "Found" mailbox.
