If you are experiencing issues attaching Word documents from OneDrive to emails, it may be due to the integration settings or the default mail client you are using. If you are using New Outlook as your default mail client, it is not MAPI-compliant, which can lead to problems when trying to send files directly from Office applications. Switching to Classic Outlook may resolve this issue.
Additionally, if you are unable to share files or attach them, ensure that your OneDrive and Office applications are updated to the latest versions. You can also check the OneDrive settings to ensure everything is configured correctly for sharing and collaboration.
If the problem persists, consider reaching out to Microsoft Support for further assistance.
