Salesforce for Outlook (SFO) OAuth Reauthentication Steps

Udgivelsesdato: Apr 30, 2026
Beskrivelse

This article describes how to completely reauthenticate Salesforce for Outlook (SFO) by removing the existing OAuth session. Salesforce for Outlook (SFO) is a Salesforce integration for Microsoft Outlook that syncs contacts, events, and tasks between Salesforce and Outlook on a user's local machine.


Users need to reauthenticate when they experience login failures, expired tokens, or connection errors between SFO and Salesforce. OAuth (Open Authorization) is the authentication protocol SFO uses to connect securely to Salesforce without storing a password.


Important: Salesforce for Outlook is approaching end of life. Review the migration guide in the Additional Resources section to move to next-generation products.

Løsning

Follow the steps below to reauthenticate Salesforce for Outlook and revoke the existing OAuth connected app session.

Step 1 — Reauthenticate via Salesforce for Outlook Settings

  1. Navigate to the Salesforce for Outlook icon in the system tray on the local machine.
  2. Right-click the SFO icon and click Settings.
  3. On the Salesforce for Outlook Settings popup box, click the Change user button, re-enter your user credentials, click Next, and complete the wizard.

Step 2 — Revoke the OAuth Connected App (if Step 1 does not resolve the issue)

If users still have problems connecting SFO to Salesforce, revoke the OAuth Connected App access and then reauthenticate.
