Microsoft Office has always been an important part of Microsoft’s overall strategy, but Office 365 is seemingly now the most important aspect of Microsoft’s core enterprise business. The company has been busy securing partnerships that add useful applications to Office 365 with this week’s addition being no exception.

Microsoft announced today that it has entered into a “long-term strategic partnership” with DocuSign to offer the latter’s eSignature apps across all of Office 365. What this means is that Office 365 will now be able to submit and digitally sign documents without having to leave Office. It’s a win for DocuSign as its product will be used in more places and it’s a win for Microsoft as it keeps users inside the Office ecosystem.

“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, vice president of Marketing, Microsoft Office. “This partnership with DocuSign helps our customers keep transactions digital and manage eSignatures seamlessly from within Office 365, where they already communicate, collaborate and create.”

Here’s a list of benefits users will experience thanks to this partnership:

“We’re excited about the momentum behind Office 365 and customers making the transition from their traditional Office applications to all-new scenarios enabled by cloud services,” said Keith Krach, chairman and CEO, DocuSign. “We believe Office 365 customers of all sizes will appreciate the seamless availability of DocuSign integrated into the applications they use every day. The combination of Microsoft and DocuSign further helps organizations keep business digital, and leverages the power of the cloud to help them focus on business results.”
