Thanks, for the info on importing to a new pst. I have the old ansi format (but in a relatively new profile in Outlook 2010. No idea how that happened) and found a way to repairit but forget what I did last week (gone fishing for 4 days, so my brain did a reset).
I'll create a new profile and do an import. That should inoculate me against future problems.
I successfully created a new profile with new non-ansi pst file then imported all folders (dozens of them) into the new structure. email works fine. Problem is my old structure with inbox is still there and still receiving email. That is, new email loades to BOTH inboxes. the new one is set as default. What's going on?
Also, the import did not import rules; I lost them all.
