   caution

   In environments where B2B integration is enabled, when attachments are sent to external users via SharePoint integration, the external users are registered as guest accounts in Microsoft Entra ID. Also, even when external sharing is performed with SharePoint alone without using our service, external users are registered as guest accounts without the users being aware of it. This is the Microsoft specification as of March 2026.

5. If the account you signed in with in step 3 differs from the account using Outlook, the following screen appears. Click × to close the Outlook Add-in Settings Menu, then open the Outlook Add-in Settings Menu again.
