Error 'Please wait while the app loads, or close the app and open it again' in Salesforce Outlook Integration

Why This Fix Works

The Salesforce Outlook Integration stores your organization URL and organization ID in Office 365 roaming settings. When these values become outdated (for example, after a My Domain change), the add-in cannot connect to Salesforce. Clearing these cached values forces the add-in to re-fetch the current Salesforce organization settings on next load.

Steps to Clear Cached Values from Office 365

Step 1: Open the Salesforce Outlook Integration in your Chrome browser. Press F12 to open Developer Tools, or go to the Chrome menu and select More Tools > Developer Tools. Click the Console tab. (Shortcut: Shift + Control + I)

Step 2: In the top-left corner of the Console window, there is a dropdown list that shows the word top. Click this dropdown and select the frame labeled baseFrameName....mailapp.force.com if you are using Office 365. If you are using an on-premise Exchange server, look for a frame ending in mailapp.force.com. Once selected, the Outlook Integration panel highlights to confirm you chose the correct frame.

Step 3: At the very bottom of the Console window, locate the input area indicated by a cursor symbol (>). This is the command line where you will enter the commands.

Step 4: Enter the following three commands one at a time, pressing Enter after each one:

Office.context.roamingSettings.set('orgUrl', '');
Office.context.roamingSettings.set('orgId', '');
Office.context.roamingSettings.saveAsync();

Step 5: You can disregard any 'undefined' errors that appear after each command. These are expected and do not indicate a problem.

Step 6: If needed, you can enter the commands on the command line one at a time, pressing Enter after each line. Continue to disregard any 'undefined' errors.
