Not to worry, {{{realthog}}}, I've been creating my very own email folders for years. However, given the number of my correspondents, it would be self-defeating organize the mail that way. The sheer volume would entail a series of nested folders. Once you get to that level, you're applying organization for organization's sake--never a very efficient means of operation.
Instead, I've created a series of dated archive folders. Once my In and Out boxes reach a certain size, I'll dump the bulk in an appropriate folder.
The irritating thing is I would've done that ages ago if somebody--ANYBODY--from Qualcom had bothered to mention this little "program feature" during any of the half dozen times I called. I mean, come on, who among us keeps their inboxes below 1 MB? Our Tech Support at the Pentagon couldn't enforce a 10 MB limit five years ago.
Hugs and headshakes,
Jean Marie
