Integrating Third-Party Storage Services with Webmail

Microsoft Outlook on the web (webmail) is adding support support for select third-party storage services. In addition to OneDrive for Business, you are able to store and share documents using services like  Box.

After connecting a third-party storage provider to your Office 365 webmail account you're able to share and attach files directly from webmail.
