I have yet to find a satisfactory answer to this issue. Periodically (like
sometimes twice a week, sometimes every day), my exchange backup which normally
takes 2.5 hours, takes over 13 hours to complete or fails. The message is:
WARNING: Username?Top of information store?.... This file cannot verify.
these are generally really old emails, so obviously a problem with my Exchange
setup too, but why some days and not others?
