With the "Mail" option selected in the bottom left hand corner of your
Outlook screen (options are: Mail, Calender, Contacts, Tasks), the left hand
display column should show the "Mail Folders". This is were you should see
the 'Personal Folders." Your Personal Folder holds other folders such as:
deleted items, drafts, inbox, outbox, etc. At some point I noticed that an
identical personal folder was listed. All the information was the same in
each one. I didn't know why and was cautious about deleting it. As best as
I can figure, I thought that installing the personal folder backup for
outlook had caused it. Anyhow, I selected it by right clicking, and chose to
"close" the folder. I hope this helps you because I never found anything or
anyone to help me solve this problem. Good Luck!
