When adding an attachment to an email in Microsoft 365, users will be prompted to attach the document as a copy before sending the document. Email accounts outside of the organization will not have the correct permissions to access the documents in OneDrive. The recipients will also need to be logged into the Microsoft 365 portal in order to access the documents. When sharing documents from OneDrive, you will need to make sure that the accounts are part of the ISU network.
