  • HI is it possible to whitelist specific email from the blocked dumain to access site?

  • The maximum number of domain that can be added is 500 and not 60 in SharePoint admin Portal.

  • Great overview… can you share how this interacts with the Azure AD B2B settings for external collaboration. Are these SharePoint settings in addition to those in AAD (ie: AAD takes precedence), or are they two distinct settings?
