Since upgrading to Yosemite I have been having issues with searching in Mail. When I search on a string I get the expected results, including the name of the mailbox where the message resides. The name of the mailbox is NO LONGER a link. Previously I was able to click on the name of the mailbox and the mailbox would be shown to me under Mailboxes. I have dozen of mailboxes and thousands of emails that have been created and accumulated over many years. I talked to Apple the other day and they acknowledged that this feature has been removed from Mail. I am looking for some suggestions on how to find a mailbox if I know its name. Any help would be greatly appreciated. Thanks
