| #### Test fallback code for Outlook on Windows "about:blank" bug | ||
|
|
||
| Outlook 2016 and 2019 on Windows have a bug when using WebView2. MSAL v3 will detect that NAA is not available and attempt to open a dialog from the task pane to sign in the user. MSAL calls `window.open` with `about:blank`, but Outlook does not handle this correctly and displays an error to the user. |

WebView2 supports about:blank, it is IE that does not support it

| We provided sample code to work around this by using the Office dialog API to successfully sign in the user. For more information, see [Outlook add-in with SSO using nested app authentication](https://github.com/OfficeDev/Office-Add-in-samples/tree/main/Samples/auth/Outlook-Add-in-SSO-NAA), and specifically the **Fallback code** section of the readme. |

You might want to reference the IE sample, since this bug only applies to IE.
