[Evolution] Moving e-mails from one folder to another

[John Lauterbach <lauterba bellsouth net>]

I am using Evolution 3.2.3 running under Ubuntu 12.04 64-bit.  I am still having difficulty moving e-mail from one folder to another.  If I group e-mails by sender in InBox, I can move each of those groups of e-mails to a folder/subfolder I maintain for each sender.  If I group e-mails in Sent by recipient and want to move them to a folder or subfolder, Evolution tells me the folder or subfolder does not exist.  The same thing happened when I moved mail from a subfolder called CompanyA to a sub-subfolder named EmployeeA which is under CompanyA.  I have hundred of e-mails in Sent that need to be moved to various folders and subfolders.

How can I do this efficiently?
