Configure fast shutdown behavior

This policy setting controls Outlook's "fast shutdown" behavior.

If you enable this policy setting, you may select one of these options:

- MAPI provider does not support: Outlook should always use Fast Shutdown unless a MAPI provider explicitly does not support it.
- All MAPI providers support: Outlook only uses Fast Shutdown if all MAPI providers do support it.
- Never: Outlook never uses Fast Shutdown

If you disable or do not configure this policy setting, the behavior will be the same as the "MAPI provider does not support" option.
