When you open the Sales Copilot pane in Microsoft Outlook, the An update to this add-in is available that requires your review and confirmation to install error is displayed.

When you select Update, the behavior depends based on whether you're using the Outlook on the web or desktop app.

Add-in error

If you're using Outlook on the web, a new browser window is launched, and you're navigated to the Sales Copilot for Microsoft Outlook screen on the Add-Ins for Outlook popup window. The error message is still displayed in the new browser window. However, on the original browser window, you can temporarily use Sales Copilot until the page is refreshed, and you see the original error message.

If you're using the Outlook desktop app, a subsequent error message is displayed indicating that the add-in is currently upgrading. When you close the Sales Copilot pane and reopen it, Sales Copilot temporarily works until you close or reopen Outlook, and the error reoccurs.

Root cause and resolution

Issue 1: Permission changes in the new Sales Copilot add-in for Outlook

Root cause

Certain permission changes require explicit administrator consent or reinstallation of the Sales Copilot Outlook add-in. These permission changes are always tied to a recent update to the Sales Copilot Outlook add-in. You can check when the latest update has been applied to the add-in on the corresponding App Source Details page. If you see a recent update to the Sales Copilot Outlook add-in, it's likely that the error is tied to corresponding permission changes due to the update.


The first step is to identify if the Sales Copilot Outlook add-in is admin-managed or user-managed. You can take the resolution steps accordingly.

  1. Open Outlook (web or desktop).

  2. Select Get Add-Ins on the Home tab in the ribbon.

  3. In the Add-Ins for Outlook window, check if the Sales Copilot for Microsoft Outlook add-in is listed under the Admin-managed section.

  4. If the add-in is listed under the Admin-managed section, ask your tenant administrator to follow these steps:

    1. In the Microsoft 365 admin center, select Settings > Integrated apps.

    2. On the Integrated apps page, select the Sales Copilot app.

      The Microsoft Sales Copilot panel opens.

    3. If the Update button is available, select it, and follow the prompts to update the add-in.

    4. If the Update button isn't available, go to the Configuration tab, select Sales Copilot for Microsoft Outlook, and then select Remove. Once done, reinstall the Sales Copilot add-in for Microsoft Outlook. More information: Install Sales Copilot

  5. If the add-in isn't listed under the Admin-managed section, uninstall the add-in from the My add-ins section, and reinstall it.


It can take up to 24 hours for the changes to take effect for the end users when deployed through the admin managed flow.
