Salesforce for Outlook: Define Conflict Behavior

Conflict behavior settings determine what happens when Salesforce for Outlook encounters a conflict when syncing data both ways.  A conflict occurs when the same record is updated in both Salesforce and Outlook or when a record is updated on one side and deleted in the other.

  1. Click Your Name | Setup | Desktop Administration | Outlook Configurations.
  2. Edit a configuration, and select a conflict behavior under Data Settings for each object being synced.  Possible options are:
    • always wins
    • Outlook always wins
  3. Click Save.  All changes take effect the next time data syncs for the users in this configuration.
