Prerequisites
A minimum Microsoft 365 Business Standard + Microsoft Entra ID P1 subscription is required (see Vanta Integrations that may Require a Premium Service)
'Global Administrator' role in Microsoft Office365.
If you have multiple IDPs connected, Office 365 must be set as your Primary IDP to use SSO login methods.

You will be taken to the App Overview page. click Users and Groups

If you want the application to be applied to all users, then it's recommended to search for and select the 'All Users' group as seen in the screenshot below, as this will ensure future users added to the group are automatically assigned the Vanta O365 app
Click Select, then Assign to finish assigning the app

Common Issues
When attempting to login I'm redirected to a page saying "Account Not Found"
The option to enable SSO is grayed out or not appearing in Vanta
Resolution
The most common cause for this error is the "Vanta O365" has not been assigned to that user's profile in Entra ID, or they are not assigned to the group that automatically provisions the app.
Check that the user:
is assigned to the group where the Vanta O365 app was applied
has the app assigned to their Entra ID user profile
has Office365 as the primary source of their employment information (see here on how to check this)
Is using the email address registered to their Vanta profile
Once these checks are complete, have the user:
clear the browser cache and cookies
in an Incognito browser, go to this page: https://app.vanta.com/login
enter their Vanta associated address and click 'Continue with email'
SSO option is grayed out or not appearing - If the option to enable SSO is grayed out or does not appear in Vanta, this is typically caused by the Office 365 integration not being configured to populate the People page.
To resolve this:
Go to your Vanta integrations settings and open the Office 365 integration.
Ensure the toggle for "Use Office 365 to populate the People Page" is turned on.
Once this toggle is enabled, the SSO option will become available and the magic link will no longer be grayed out.
