Microsoft and eSignature service DocuSign today announced a long-term partnership that will make it easy for Office 365 subscribers to submit and sign documents without leaving Microsoft’s Office apps.

This new solution, the two companies announced, will be available in the Office Store early next month and was built on top of Microsoft Office platform. The app will be integrated into Outlook, Word, SharePoint Online and SharePoint Server 2013. This means that Office 365 and SharePoint admins will be able to add the service remotely for all of their users, and the tool will also be integrated with the Azure Active Directory, so there is no need for a separate sign-in to use DocuSign from within Microsoft’s applications.

All the documents will be stored on OneDrive for Business (formerly SkyDrive).

Overall, this is a pretty straightforward integration, but it does make choosing Office a bit more easy for companies that rely heavily on DocuSign. For Microsoft, it is also an opportunity to talk about the ecosystem of applications that exist around its Office suite.

“Leading partners like DocuSign are building apps on the Office platform to help our customers get more value directly from their most highly used applications,” said John Case, the vice president of marketing for Microsoft Office, in the announcement today.
