Tony I think your a little confused. On-line backups are not done with
'M.S's MAPI', it's done through MS's api calls. MAPI is a interface used =
by
the older Microsoft Mail client. MAPI is the interface that the brick lev=
el
backup people use to extract the information from the Exchange Informatio=
n
Store. PST files are personal folders that can be stored locally and hold
Outlook information such as email, calendar, etc. The recommended Microso=
ft
approach is to restore the entire Information Store to another server and
export the user's mailbox to a personal folder, ie:PST. Then import that
information into the production Exchange servers information store.
