Must RESTORE a mailbox!
Deleted a mailbox with lots of important emails in it. Transferred from old iMac but name corrupted. How do I restore it? Tried Toshiba external storage from old Mac, but still NO mailbox. Help!!

You can try this process:
To restore mailbox:
Open Finder
Click “GO” in top menu bar then click option key
Open mail folder
Open V9(or similar) folder
Then find the folders labeled with cryptic titles (at this point you could open TM if you want to go back in time)
Look down through those folders to find a mailbox (note: there may be more than one with same label).
If it contains email you want you can copy the entire folder to your desktop
Go back into mail and import that folder from your desktop
