Turn on logging for all conflicts

This policy setting allows you to create Modification Resolution logs whenever the Outlook conflict resolver runs.

If you enable this policy setting, Outlook will create Modification Resolution logs whenever the Outlook conflict resolver runs. By default, Modification Resolution logs are written into the Sync Issues folder whenever Outlook's conflict resolver cannot resolve a conflict.

You may select one of these options:
- No conflicts are logged: No Modification Resolution logs are written into the Sync Issues folder whenever Outlook's conflict resolver runs.
- All conflicts logged: Modification Resolution logs are written into the Sync Issues folder whenever Outlook's conflict resolver runs.
- Unresolved conflicts logged only: Modification Resolution logs are written into the Sync Issues folder in Outlook when the Outlook conflict resolver cannot resolve a conflict.

This applies to all item types.

If you disable or do not configure this policy setting, no Modification Resolution logs are written when the Outlook conflict resolver runs.

Supported on: At least Windows 7
