Fix Microsoft Graph API Errors in Cirrus Insight Outlook Sidebar

Overview

Users may see one of the following messages in the Cirrus Insight sidebar in Outlook:

• “Unable to access Microsoft Graph API”
• “Update Microsoft Connection”

Cause: An outdated Cirrus Insight Outlook add-in that no longer supports current Microsoft Graph API requirements.

Resolution: Fully remove the existing add-in, install the latest version from the Microsoft 365 App Store, and complete admin consent (if applicable).

Affected Cirrus Insight Environments

• Outlook Sidebar (Desktop)
• Office 365 Web Application (Web Version of Outlook)

Step 1: Check Your Current Version

1. Open Outlook and load the Cirrus Insight sidebar
2. Right-click anywhere inside the Cirrus Insight sidebar
3. Select Inspect
   
4. In DevTools, locate: manifestVersion=YYYY.MM.DD
   

Result:

• Manifest Version prior to 2025 (e.g., 2023.10.11) → update required, as shown in the above example
• Manifest Version 2025.6.10 or newer → no update required, restart Outlook, and the Cirrus sidebar will work as expected

Step 2: Reinstall the Add-in

Individual Install

1. Open Outlook
2. Go to Get Add-ins / Manage Add-ins
3. Remove Cirrus Insight
4. Reinstall from the Microsoft 365 App Store

Admin-Managed Install

If the add-in cannot be removed, it is managed by an Office 365 admin.

Admin Steps

1. Go to Microsoft 365 Admin Center
• Direct link: admin.cloud.microsoft/?#/Settings/AddIns
2. Navigate to Integrated Apps -> Add-ins
3. Locate Cirrus Insight
4. Remove the existing add-in
5. Deploy the latest version of Cirrus Insight

Step 3: Approve Microsoft Graph Permissions (Admin)

After reinstalling, admin consent is required.

• A new Enterprise Application will appear in Azure / Entra ID:
• Cirrus Insight for Outlook

Admin Consent Link:

Step 4: Allow Time for Deployment

For Admin deployments, Microsoft propagation may take up to 72 hours.

Recommended actions:

• Restart Outlook
• Relaunch Microsoft 365 apps
  

Additional Tip (Admin Check): Even after reinstalling the new sidebar, confirm with a Microsoft 365 administrator that the add-in is fully updated:

1. Go to Microsoft 365 Admin Center

3. Locate Cirrus Insight
4. Check for an “Update” button
• If present, run the update directly from the admin view

• If the issue persists after reinstall:
• Confirm the installed manifest version for Cirrus Insight
• Capture screenshots of the error
• Confirm admin consent was completed
• Escalate to Cirrus Insight Support
