My situation was the Win Mail Compact would not complete.
Steps I took were:
1. Run the Compact Database tool from
http://www.oehelp.com/WMUtil/Default.aspx
Completes OK.
2. Try Win Mail Compact - same result - would not complete.
3. Run the Repair Database tool - this has a warning - and it left me with
no
local folders or messages (Panic). Won't use this in a hurry again.
4. Run System Restore. This gets my messages in a number of folders
named "Recovered Messages (date)".
5. Recreate each news server I had - download newsgroups list - subscribe to
those newsgroups I use.
6. Setup Local Folders for every one I archive (e.g. MS for all emails from
MS worth
keeping, ditto from Bank, Etc, etc) - then move all the messages from the
Recovered Messages folders to these new ones.
7. This left me with some problems - e.g. I lost all the watched messages I
had
tagged in several newsgroups, ditto all messages "unread".
8. Tried the suggestion of Exporting the appropriate folder under
C:\Users\Bill\AppData\Local\Microsoft\Windows Mail to a portable drive.
This failed - too big. Strange - approx 900MB.
Haven't resolved this - looking for a backup tool. Unsure whether normal
copy of this file will work in an emergency. Maybe someone can advise.
9. In summary - I managed to recover sufficiently for my purposes - I'm
retired, so
data is personal, but valuable to me. Were I still in business I'd be
very unhappy.
More good luck than knowledge I'm afraid. I've stuck with AVG AV for now.
BTW - Win Mail Compact works OK now - the original objective!
