We have a client whose users routinely need to search a shared out Zimbra mailbox with a very extensive nested folder tree under the Inbox folder.

For a variety of reasons, the emails desired to be found by the customer service agents doing the searching could be in any number of folders. Further, the customer service agent needs to do the searching while on the phone with a customer.

Consequently, the agents have taken to typing "under:inbox <search term>" in the Search bar window. But, this takes time and we have been asked if there is a way to configure Zimbra's search to default to "under:" instead of "in:"

Is this possible and if so, how do we implement?
