    Fault : Outlook keeps asking for a password and will not accept it
    Fix   : Build a fresh mail profile
    Source: https://jbtecwiz.com/support/win-app-outlook-password

    Run as     : Control Panel -> Mail
    Expect     : 45 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    Neither of the above worked. A damaged profile cannot be repaired
    reliably and rebuilding is faster than trying.

    HOW TO UNDO IT
    The old profile remains until you delete it -- switch back at the
    profile prompt.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
